2. Chemistry
The coloration of thesurfaceof animals is caused either bypigments, or by a certainstructureof the surface by means of which the light falling on it, or reflected through its superficial transparent layers, undergoes diffraction or other optical change. Or it may be the result of a combination of these two causes. It plays an important part in the relationship of the animal to its environment, in concealment, in mimicry, and so on; the presence of a pigment in the integument may also serve a more direct physiological purpose, such as a respiratory function. The coloration of birds’ feathers, of the skin of many fishes, of many insects, is partially at least due to structure and the action of the peculiar pigmented cells known as “chromatophores†(which W. Garstang defines as pigmented cells specialized for the discharge of the chromatic function), and is much better marked when these have for their background a “reflecting layer†such as is provided by guanin, a substance closely related to uric acid. Such a mechanism is seen to greatest advantage in fishes. Among these, guanin may be present in a finely granular form, causing the light falling on it to be scattered, thus producing a white effect; or it may be present in a peculiar crystalline form, the crystals being known as “iridocytesâ€; or in a layer of closely apposed needles forming a silvery sheet or mirror. In the iris of some fishes the golden red colour is produced by the light reflected from such a layer of guanin needles having to pass through a thin layer of a reddish pigment, known as a “lipochrome.†Again, in some lepidopterous insects a white or a yellow appearance is produced by the deposition of uric acid or a nearly allied substance on the surface of the wings. In many animals, but especially among invertebrates, colouring matters or pigments play an important rôle in surface coloration; in some cases such coloration may be of benefit to the animal, but in others the integument simply serves as an organ for the excretion of waste pigmentary substances. Pigments (1) may be of direct physiological importance; (2) they may be excretory; or (3) they may be introduced into the body of the animal with the food.
Of the many pigments which have been described up to the present time, very few have been subjected to elementary chemical analysis, owing to the great difficulties attending their isolation. An extremely small amount of pigment will give rise to a great amount of coloration, and the pigments are generally accompanied by impurities of various kinds which cling to them with great tenacity, so that when one has been thoroughly cleansed very little of it remains for ultimate analysis. Most of these substances have been detected by means of the spectroscope, their absorption bands serving for their recognition, but mere identity of spectrum does not necessarily mean chemical identity, and a few chemical tests have also to be applied before a conclusion can be drawn. The absorption bands are referred to certain definite parts of the spectrum, such as the Fraunhofer lines, or they may be given in wave-lengths. For this purpose the readings of the spectroscope are reduced to wave-lengths by means of interpolation curves; or if Zeiss’s microspectroscope be used, the position of bands in wave-lengths (denoted by the Greek letter λ) may be read directly.
Haemoglobin, the red colouring matter of vertebrate blood, C758H1203N195S3FeO218, and its derivatives haematin, C32H30N4FeO3, and haematoporphyrin, C16H18N2O3, are colouring matters about which we possess definite chemical knowledge, as they have been isolated, purified and analysed. Most of the bile pigments of mammals have likewise been isolated and studied chemically, and all of these are fully described in the text-books of physiology and physiological chemistry. Haemoglobin, though physiologically of great importance in the respiratory process of vertebrate animals, is yet seldom used for surface pigmentation, except in the face of white races of man or in other parts in monkeys, &c. In some worms the transparent skin allows the haemoglobin of the blood to be seen through the integument, and in certain fishes also the haemoglobin is visible through the integument. It is a curious and noteworthy fact that in some invertebrate animals in which no haemoglobin occurs, we meet with its derivatives. Thus haematin is found in the so-called bile of slugs, snails, the limpet and the crayfish. In sea-anemones there is a pigment which yields some of the decomposition-products of haemoglobin, and associated with this is a green pigment apparently identical with biliverdin (C16H18N2O4), a green bile pigment. Again, haematoporphyrin is found in the integuments of star-fishes and slugs, and occurs in the “dorsal streak†of the earth-wormLumbricus terrestris, and perhaps in other species. Haematoporphyrin and biliverdin also occur in the egg-shells of certain birds, but in this case they are derived from haemoglobin. Haemoglobin is said to be found as low down in the animal kingdom as the Echinoderms,e.g.inOphiactis virensandThyonella gemmata. It also occurs in the blood ofPlanorbis corneusand in the pharyngeal muscles of other mollusca.
A great number of other pigments have been described; for example, in the muscles and tissues of animals, both vertebrate and invertebrate, are the histohaematins, of which a special muscle pigment, myohaematin, is one. In vertebrates the latter is generally accompanied by haemoglobin, but in invertebrates—with the exception of the pharyngeal muscles of the mollusca—it occurs alone. Although closely related to haemoglobin or its derivative haemochromogen, the histohaematins are yet totally distinct, and they are found in animals where not a trace of haemoglobin can be detected. Another interesting pigment is turacin, which contains about 7% of nitrogen, found by Professor A. H. Church in the feathers of the Cape lory and other plantain-eaters, from which it can be extracted by water containing a trace of ammonia. It has been isolated, purified and analysed by Professor Church. From it may be obtained turacoporphyrin, which is identical with haematoporphyrin, and gives the band in the ultra-violet which J. L. Soret and subsequently A. Gamgee have found to be characteristic of haemoglobin and its compounds. Turacin itself gives a peculiar two-banded spectrum, and contains about 7% of copper in its molecule. Another copper-containing pigment is haemocyanin, which in the oxidized state gives a blue colour to the blood of various Mollusca and Arthropoda. Like haemoglobin, it acts as an oxygen-carrier in respiration, but it takes no part in surface coloration.
A class of pigments widely distributed among plants and animals are the lipochromes. As their name denotes, they are allied to fat and generally accompany it, being soluble in fat solvents. They play an important part in surface coloration, and may be greenish, yellow or red in colour. They contain no nitrogen. As an example of a lipochrome which has been isolated, crystallized and purified, we may mention carotin, which has recently been found in green leaves. Chlorophyll, which is so often associated with a lipochrome, has been found in some Infusoria, and inHydraandSpongilla, &c. In some cases it is probably formed by the animal; in other cases it may be due to symbiotic algae, while in the gastric gland of many Mollusca, Crustacea and Echinodermata it is derived from food-chlorophyll. Here it is known as entero-chlorophyll. The black pigments which occur among both vertebrate and invertebrate animals often have only one attribute in common, viz. blackness, for among the discordant results of analysis one thing is certain, viz. that the melanins from vertebrate animalsare not identical with those from invertebrate animals. The melanosis or blackening of insect blood, for instance, is due to the oxidation of a chromogen, the pigment produced being known as a uranidine. In some sponges a somewhat similar pigment has been noticed. Other pigments have been described, such as actiniochrome, echinochrome, pentacrinin, antedonin, polyperythrin (which appears to be a haematoporphyrin), the floridines, spongioporphyrin, &c., which need no mention here; all these pigments can only be distinguished by means of the spectroscope.
Most of the pigments are preceded by colourless substances known as “chromogens,†which by the action of the oxygen of the air and by other agencies become changed into the corresponding pigments. In some cases the pigments are built up in the tissues of an animal, in others they appear to be derived more or less directly from the food. Derivatives of chlorophyll and lipochromes especially, seem to be taken up from the intestine, probably by the agency of leucocytes, in which they may occur in combination with, or dissolved by, fatty matters and excreted by the integument. In worms especially, the skin seems to excrete many effete substances, pigments included. No direct connexion has been traced between the chlorophyll eaten with the food and the haemoglobin of blood and muscle. Attention may, however, be drawn to the work of Dr E. Schunck, who has shown that a substance closely resembling haematoporphyrin can be prepared from chlorophyll; this is known as phylloporphyrin. Not only does thevisiblespectrum of this substance resemble that of haematoporphyrin, but theinvisibleultra-violet also, as shown by C. A. Schunck.

COLSTON, EDWARD(1636-1721), English philanthropist, the son of William Colston, a Bristol merchant of good position, was born at Bristol on the 2nd of November 1636. He is generally understood to have spent some years of his youth and manhood as a factor in Spain, with which country his family was long connected commercially, and whence, by means of a trade in wines and oil, great part of his own vast fortune was to come. On his return he seems to have settled in London, and to have bent himself resolutely to the task of making money. In 1681, the date of his father’s decease, he appears as a governor of Christ’s hospital, to which noble foundation he afterwards gave frequently and largely. In the same year he probably began to take an active interest in the affairs of Bristol, where he is found about this time embarked in a sugar refinery; and during the remainder of his life he seems to have divided his attention pretty equally between the city of his birth and that of his adoption. In 1682 he appears in the records of the great western port as advancing a sum of £1800 to its needy corporation; in 1683 as “a free burgess andmeire(St Kitts) merchant†he was made a member of the Merchant’s Hall; and in 1684 he was appointed one of a committee for managing the affairs of Clifton. In 1685 he again appears as the city’s creditor for about £2000, repayment of which he is found insisting on in 1686. In 1689 he was chosen auditor by the vestry at Mortlake, where he was residing in an old house once the abode of Ireton and Cromwell. In 1691, on St Michael’s Hill, Bristol, at a cost of £8000, he founded an almshouse for the reception of 24 poor men and women, and endowed with accommodation for “Six Saylors,†at a cost of £600, the merchant’s almshouses in King Street. In 1696, at a cost of £8000, he endowed a foundation for clothing and teaching 40 boys (the books employed were to have in them “no tincture of Whiggismâ€); and six years afterwards he expended a further sum of £1500 in rebuilding the school-house. In 1708; at a cost of £41,200, he built and endowed his great foundation on Saint Augustine’s Back, for the instruction, clothing, maintaining and apprenticing of 100 boys; and in time of scarcity, during this and next year, he transmitted “by a private hand†some £20,000 to the London committee. In 1710, after a poll of four days, he was sent to parliament, to represent, on strictest Tory principles, his native city of Bristol; and in 1713, after three years of silent political life, he resigned this charge. He died at Mortlake in 1721, having nearly completed his eighty-fifth year; and was buried in All Saints’ church, Bristol.
Colston, who was in the habit of bestowing large sums yearly for the release of poor debtors and the relief of indigent age and sickness, and who gave (1711) no less than £6000 to increase Queen Anne’s Bounty Fund for the augmentation of small livings, was always keenly interested in the organization and management of his foundations; the rules and regulations were all drawn up by his hand, and the minutest details of their constitution and economy were dictated by him. A high churchman and Tory, with a genuine intolerance of dissent and dissenters, his name and example have served as excuses for the formation of two political benevolent societies—the “Anchor†(founded 1769) and the “Dolphin†(founded 1749),—and also the “Grateful†(founded 1758), whose rivalry has been perhaps as instrumental in keeping their patron’s memory green as have the splendid charities with which he enriched his native city (seeBristol).

COLT, SAMUEL(1814-1862), American inventor, was born on the 19th of July 1814 at Hartford, Connecticut, where his father had a manufactory of silks and woollens. At the age of ten he left school for the factory, and at fourteen, then being in a boarding school at Amherst, Massachusetts, he made a runaway voyage to India, during which (in 1829) he constructed a wooden model, still existing, of what was afterwards to be the revolver (seePistol). On his return he learned chemistry from his father’s bleaching and dyeing manager, and under the assumed name “Dr Coult†travelled over the United States and Canada lecturing on that science. The profits of two years of this work enabled him to continue his researches and experiments. In 1835, having perfected a six-barrelled rotating breech, he visited Europe, and patented his inventions in London and Paris, securing the American right on his return; and the same year he founded at Paterson, New Jersey, the Patent Arms Company, for the manufacture of his revolvers only. As early as 1837 revolvers were successfully used by United States troops, under Lieut.-Colonel William S. Harney, in fighting against the Seminole Indians in Florida. Colt’s scheme, however, did not succeed; the arms were not generally appreciated; and in 1842 the company became insolvent. No revolvers were made for five years, and none were to be had when General Zachary Taylor wrote for a supply from the seat of war in Mexico. In 1847 the United States government ordered 1000 from the inventor; but before these could be produced he had to construct a new model, for a pistol of the company’s make could nowhere be found. This commission was the beginning of an immense business. The little armoury at Whitneyville (New Haven, Connecticut), where the order for Mexico was executed, was soon exchanged for larger workshops at Hartford. These in their turn gave place (1852) to the enormous factory of the Colt’s Patent Fire-Arms Manufacturing Company, doubled in 1861, on the banks of the Connecticut river, within the city limits of Hartford, where so many millions of revolvers with all their appendages have been manufactured. Thence was sent, for the Russian and English governments, to Tula and Enfield, the whole of the elaborate machinery devised by Colt for the manufacture of his pistols. Colt introduced and patented a number of improvements in his revolver, and also invented a submarine battery for harbour defence. He died at Hartford on the 10th of January 1862.
COLT’S-FOOT, the popular name of a small herb,Tussilago Farfara, a member of the natural order Compositae, which iscommon in Britain in damp, heavy soils. It has a stout branching underground stem, which sends up in March and April scapes about 6 in. high, each bearing a head of bright yellow flowers, the male in the centre surrounded by a much larger number of female. The flowers are succeeded by the fruits, which bear a soft snow-white woolly pappus. The leaves, which appear later, are broadly cordate with an angular or lobed outline, and are covered on the under-face with a dense white felt. The botanical name,Tussilago, recalls its use as a medicine for cough (tussis). The leaves are smoked in cases of asthma.
COLUGO,orCobego, either of two species of the zoological genusGaleopithecus. These animals live in the forests of the Malay Peninsula, Sumatra, Borneo and the Philippine Islands, where they feed chiefly on leaves, and probably also on insects. In size they may be compared with cats; the long slender limbs are connected by a broad fold of skin extending outwards from the sides of the neck and body, the fingers and toes are webbed, and the hind-limbs joined by an outer membrane as in bats. Their habits are nocturnal, and during the daytime they cling to the trunks or limbs of trees head downwards in a state of repose. With the approach of night their season of activity commences, when they may be occasionally seen gliding from tree to tree supported on their cutaneous parachute, and they have been noticed as capable of traversing in this way a space of 70 yds. with a descent of only about one in five. Europeans in the East know these animals as “flying lemurs.†(SeeGaleopithecus.)
COLUMBA, SAINT(Irish,Colum), Irish saint, was born on the 7th of December 521, in all probability at Gartan in Co. Donegal. His father Feidlimid was a member of the reigning family in Ireland and was closely allied to that of Dalriada (Argyll). His mother Eithne was of Leinster extraction and was descended from an illustrious provincial king. To these powerful connexions as much as to his piety and ability, he owed the immense influence he possessed. Later lives state that the saint was also called Crimthann (fox), and Reeves suggests that he may have had two names, the one baptismal, the other secular. He was afterwards known as Columkille, or Columba of the Church, to distinguish him from others of the same name. During his early years the Irish Church was reformed by Gildas and Finian of Clonard, and numerous monasteries were founded which made Ireland renowned as a centre of learning. Columba himself studied under two of the most distinguished Irishmen of his day, Finian of Moville (at the head of Strangford Lough) and Finian of Clonard. Almost as a matter of course, under such circumstances, he embraced the monastic life. He was ordained deacon while at Moville, and afterwards, when about thirty years of age, was raised to the priesthood. During his residence in Ireland he founded, in addition to a number of churches, two famous monasteries, one named Daire Calgaich (Derry) on the banks of Lough Foyle, the other Dair-magh (Durrow) in King’s county.
In 563 he left his native land, accompanied by twelve disciples, and went on a mission to northern Britain, perhaps on the invitation of his kinsman Conall, king of Dalriada. Irish accounts represent Columba as undertaking this mission in consequence of the censure expressed against him by the clergy after the battle of Cooldrevny; but this is probably a fabrication. The saint’s labours in Scotland must be regarded as a manifestation of the same spirit of missionary enterprise with which so many of his countrymen were imbued. Columba established himself on the island of Hy or Iona, where he erected a church and a monastery. About the year 565 he applied himself to the task of converting the heathen kingdom of the northern Picts. Crossing over to the mainland he proceeded to the residence, on the banks of the Ness, of Brude, king of the Picts. By his preaching, his holy life, and, as his earliest biographers assert, by the performance of miracles, he converted the king and many of his subjects. The precise details, except in a few cases, are unknown, or obscured by exaggeration and fiction; but it is certain that the whole of northern Scotland was converted by the labours of Columba, and his disciples and the religious instruction of the people provided for by the erection of numerous monasteries. The monastery of Iona was reverenced as the mother house of all these foundations, and its abbots were obeyed as the chief ecclesiastical rulers of the whole nation of the northern Picts. There were then neither dioceses nor parishes in Ireland and Celtic Scotland; and by the Columbite rule the bishops themselves, although they ordained the clergy, were subject to the jurisdiction of the abbots of Iona, who, like the founder of the order, were only presbyters. In matters of ritual they agreed with the Western Church on the continent, save in a few particulars such as the precise time of keeping Easter and manner of tonsure.
Columba was honoured by his countrymen, the Scots of Britain and Ireland, as much as by his Pictish converts, and in his character of chief ecclesiastical ruler he gave formal benediction and inauguration to Aidan, the successor of Conall, as king of the Scots. He accompanied that prince to Ireland in 575, and took a leading part in a council held at Drumceat in Ulster, which determined once and for all the position of the ruler of Dalriada with regard to the king of Ireland. The last years of Columba’s life appear to have been mainly spent at Iona. There he was already revered as a saint, and whatever credit may be given to some portions of the narratives of his biographers, there can be no doubt as to the wonderful influence which he exercised, as to the holiness of his life, and as to the love which he uniformly manifested to God and to his neighbour.
In the summer of 597 he knew that his end was approaching. On Saturday the 8th of June he was able, with the help of one of his monks, to ascend a little hill above the monastery and to give it his farewell blessing. Returning to his cell he continued a labour in which he had been engaged, the transcription of the Psalter. Having finished the verse of the 34th Psalm where it is written, “They who seek the Lord shall want no manner of thing that is good,†he said, “Here I must stop:—what follows let Baithen writeâ€; indicating, as was believed, his wish that his cousin Baithen should succeed him as abbot. He was present at evening in the church, and when the midnight bell sounded for the nocturnal office early on Sunday morning he again went thither unsupported, but sank down before the altar and passed away as in a gentle sleep.
Several Irish poems are ascribed to Columba, but they are manifestly compositions of a later age. Three Latin hymns may, however, be attributed to the saint with some degree of certainty.
The original materials for a life of St Columba are unusually full. The earliest biography was written by one of his successors, Cuminius, who became abbot of Iona in 657. Much more important is the enlargement of that work by Adamnan, who became abbot of Iona in 679. These narratives are supplemented by the brief but most valuable notices given by the Venerable Bede. See W. Reeves,Life of St Columba, written by Adamnan(Dublin, 1857); W. F. Skene,Celtic Scotland, vol. ii. “Church and Culture†(Edinburgh, 1877).

(E. C. Q.)
COLUMBAN(543-615), Irish saint and writer, was born in Leinster in 543, and was educated in the monastery of Bangor, Co. Down. About the year 585 he left Ireland together with twelve other monks, and established himself in the Vosges, among the ruins of an ancient fortification called Anagrates, the present Anegray in the department of Haute-Saône. His enemies accused him before a synod of French bishops (602) for keeping Easter according to the old British and now unorthodox way, and a more powerful conspiracy was organized against him at the court of Burgundy for boldly rebuking the crimes of King Theuderich II. and the queen-mother Brunhilda. He was banished and forcibly removed from his monastery, and with St Gall and others of the monks he withdrew into Switzerland, where he preached with no great success to the Suebi and Alamanni. Being again compelled to flee, he retired to Italy, and founded the monastery of Bobbio in the Apennines, where he remained till his death, which took place on the 21st of November 615. His writings, which include some Latin poems, prove him a man of learning, and he appears to have been acquainted not only with the Latin classics, but also with Greek, and even Hebrew.
The collected edition of St Columban’s writings was published by Patrick Fleming in hisCollectanea sacra Hiberni(Louvain, 1667),and reproduced by Migne, p. 4, vol. lxxxvi. (Paris, 1844). See further, Wright’sBiographia Literaria. Columban’sRegula Coenobitalis cum Poenitenlialiis to be found in theCodex Regularum(Paris, 1638). A complete bibliography is given in U. Chevallier,Répertoire des sources hist. (Bio. Bibliogr.), vol. i. 990 (Paris, 1905).

COLUMBANI, PLACIDO,Italian architectural designer, who worked chiefly in England in the latter part of the 18th century. He belonged to the school of the Adams and Pergolesi, and like them frequently designed the enrichments of furniture. He was a prolific producer of chimney-pieces, which are often mistaken for Adam work, of moulded friezes, and painted plaques for cabinets and the like. There can be no question that the English furniture designers of the end of the 18th century, and especially the Adams, Hepplewhite and Sheraton, owed much to his graceful, flowing and classical conceptions, although they are often inferior to those of Pergolesi. His books are still a valuable store-house of sketches for internal architectural decoration. His principal works are:—Vases and Tripods(1770);A New Book of Ornaments, containing a variety of elegant designs for Modern Panels, commonly executed in Stucco, Wood or Painting, and used in decorating Principal Rooms(1775);A variety of Capitals, Friezes and Corniches, and how to increase and decrease them, still retaining their proportions(1776). He also assisted John Crunden in the production ofThe Chimneypiece Makers’ Daily Assistant(1776).
COLUMBARIUM(Lat.columba, a dove), a pigeon-house. The term is applied in architecture to those sepulchral chambers in and near Rome, the walls of which were sunk with small niches (columbaria) to receive the cinerary urns. Vitruvius (iv. 2) employs the term to signify the holes made in a wall to receive the ends of the timbers of a floor or roof.
COLUMBIA,a city and the county-seat of Boone county, Missouri, U.S.A., situated in the central part of the state, about 145 m. (by rail) W.N.W. of St Louis. Pop. (1890) 4000; (1900) 5651 (1916 negroes); (1910) 9662. Columbia is served by the Wabash and the Missouri, Kansas & Texas railways. It is primarily an educational centre, is a market for grain and farm products, and has grain elevators, a packing house, a shoe factory and brick works. Columbia is the seat of the University of Missouri, a coeducational state institution, established in 1839 and opened in 1841; it received no direct financial support from the state until 1867, and its founding was due to the self-sacrifice of the people of the county. It is now liberally supported by the state; in 1908 its annual income was about $650,000. In 1908 the university had (at Columbia) 200 instructors and 2419 students, including 680 women; included in its library is the collection of the State Historical Society. The School of Mines of the university is at Rolla, Mo.; all other departments are at Columbia. A normal department was established in 1867 and opened in 1868; and women were admitted to it in 1869. The College of Agriculture and Mechanic Arts became a department of the university in 1870. The law department was opened in 1872, the medical in 1873, and the engineering in 1877. The graduate department was established in 1896, and in 1908 a department of journalism was organized. On the university campus in the quadrangle is the monument of grey granite erected over the grave of Thomas Jefferson, designed after his own plans, and bearing the famous inscription written by him. It was given to the university by descendants of Jefferson when Congress appropriated money for the monument now standing over his grave. Near the city is the farm of the agricultural college and the experiment station. At Columbia, also, are the Parker Memorial hospital, the Teachers College high school, the University Military Academy, the Columbia Business College, Christian College (Disciples) for women, established in 1851, its charter being the first granted by Missouri for the collegiate education of Protestant women; the Bible College of the Disciples of Christ in Missouri; and Stephens College (under Baptist control) for women, established in 1856. The municipality owns the water-works and the electric lighting plant. Columbia was first settled about 1821.
COLUMBIA,a borough of Lancaster county, Pennsylvania, U.S.A., on the W. bank of the Susquehanna river (here crossed by a long steel bridge), opposite Wrightsville and about 81 m. W. by N. of Philadelphia. Pop. (1890) 10,599; (1900) 12,316, of whom 772 were foreign-born; (1910) 11,454. It is served by the Pennsylvania, the Philadelphia, Baltimore & Washington, the Philadelphia & Reading, and the Northern Central railways, and by interurban electric railways. The river here is about a mile wide, and a considerable portion of the borough is built on the slope of a hill which rises gently from the river-bank and overlooks beautiful scenery. The Pennsylvania railway has repair shops here, and among Columbia’s manufactures are silk goods, embroidery and laces, iron and steel pipe, engines, laundry machinery, brushes, stoves, iron toys, umbrellas, flour, lumber and wagons; the city is also a busy shipping and trading centre. Columbia was first settled, by Quakers, in 1726; it was laid out as a town in 1787; and in 1814 it was incorporated. In 1790 it was one of several places considered in Congress for a permanent site of the national capital.
COLUMBIA,the capital city of South Carolina, U.S.A., and the county-seat of Richland county, on the E. bank of the Congaree river, a short distance below the confluence of the Saluda and the Broad rivers, about 130 m. N.W. of Charleston. Pop. (1890) 15,353; (19O0) 21,108, of whom 9858 were negroes; and (1910) 26,319. It is served by the Atlantic Coast Line, the Southern, the Seaboard Air Line, and the Columbia, Newberry & Laurens railways. Columbia is picturesquely situated on the level top of a bluff overlooking the Congaree, which falls about 36 ft. in passing by, but is navigable for the remainder of its course. The surrounding country is devoted chiefly to cotton culture. The state house, United States government building and city hall are fine structures. Some of the new business houses are ten or more storeys in height. The state penitentiary and the state insane asylum are located here, and Columbia is an important educational centre, being the seat of the university of South Carolina, the Columbia College for women (Methodist Episcopal South, 1854), the College for women (Presbyterian, 1890), and the Presbyterian Theological Seminary (1828); and the Allen University (African Methodist Episcopal; coeducational, 1880), and the Benedict College (Baptist) for negroes. The University of South Carolina, organized in 1801 and opened in 1805, was known as South Carolina College in 1805-1863, 1878-1887 and 1891-1906, and as the university of South Carolina in 1866-1877, 1888-1891 and after 1906; in 1907-1908 it had departments of arts, science, pedagogy and law, an enrolment of 285 students, and a faculty of 25 instructors. By means of a canal abundant water power is furnished by the Congaree, and the city has some of the largest cotton mills in the world; it has, besides, foundries and machine shops and manufactories of fertilizers and hosiery. The manufactures under the factory system were valued at $3,133,903 in 1900 and at $4,676,944 in 1905—a gain, greater than that of any other city in the state, of 49.2% in five years. In the neighbourhood are several valuable granite quarries. The municipality owns and operates its water-works.
While much of the site was still a forest the legislature, in 1786, chose it for the new capital. It was laid out in the same year, and in 1790 the legislature first met here. Until 1805, when it was incorporated as a village, Columbia was under the direct government of the legislature; in 1854 it was chartered as a city. On the morning of the 17th of February 1865 General W. T. Sherman, on his march through the Carolinas, entered Columbia, and on the ensuing night a fire broke out which was not extinguished until most of the city was destroyed. The responsibility for this fire was charged by the Confederates upon the Federals and by the Federals upon the Confederates.
COLUMBIA,a city and the county-seat of Maury county, Tennessee, U.S.A., situated on the Duck river, in the central part of the state, 46 m. S. of Nashville. Pop. (1890) 5370; (1900) 6052 (2716 negroes); (1910) 5754. Columbia is served by the Louisville & Nashville, and the Nashville, Chattanooga & St Louis railways. It is the seat of the Columbia Institute for girls (under Protestant Episcopal control), founded in 1836, and of the Columbia Military Academy. Columbia is in a fine farmingregion; is engaged extensively in the mining and shipping of phosphates; has an important trade in live-stock, especially mules; manufactures cotton, lumber, flour, bricks, pumps and woollen goods; and has marble and stone works. Columbia was settled about 1807 and was incorporated in 1822. During the Civil War it was the base from which General N. B. Forrest operated in 1862-1863, and was alternately occupied by Confederate and Federal forces during General Hood’s Nashville campaign (November-December 1864).
COLUMBIA RIVER,a stream of the north-west United States and south-west Canada, about 939 m. in length, draining a basin of about 250,000 sq. m., of which 38,395 are in British Columbia; some 105,000 sq. m. belong to the valley of the Snake and 11,700 to that of the Willamette. The source of the river is partly in the Yellowstone country, partly near the Titon peaks, and partly in the pine-clad mountains of British Columbia. Some American geographers regard the head as that of the Clark Fork, but it is most generally taken to be in British Columbia about 80 m. north of the United States line. From this point it runs some 150 m. to the north-west to the “Big Bend,†and then in a great curve southward, enclosing the superb ranges of the Selkirks, crossing the international line near the boundary of Washington and Idaho, where it is joined by the Pend Oreille river, or Clark Fork, already referred to. This latter river rises in the Rocky Mountains west of Helena, Montana, falls with a heavy slope (1323 ft. in 167 m.) to its confluence with the Flathead, flows through Lake Pend Oreille (27 m.) in northern Idaho, and runs in deep canyons (falling 900 ft. in 200 m.) to its junction with the Columbia, which from this point continues almost due south for more than 106 m. Here the Columbia is joined by the Spokane, a large river with heavy fall, and enters the “Great Plain of the Columbia,†an area of some 22,000 sq. m., resembling the “parks†of Colorado, shut in on all sides by mountains: the Moses range to the north, the Bitter Root and Cœur d’Alène on the east, the Blue on the south, and the Cascades on the west. The soil is rich, yielding great harvests of grain, and the mountains rich in minerals as yet only slightly prospected. After breaking into this basin the river turns sharply to the west and skirts the northern mountain barrier for about 105 m. Where it strikes the confines of the Cascades, it is joined by the Okanogan, turns due south in the second Big Bend, and flows about 200 m. to its junction with the Snake near Wallula.
After the confluence of the Snake with the Columbia the greater river turns west toward the Pacific. Throughout its course to this point it may be said that the Columbia has no flood plain; everywhere it is cutting its bed; almost everywhere it is characterized by canyons, although above the Spokane the valley is much broken down and there is considerable timbered and fertile bench land. Below the Spokane the canyon becomes more steep and rugged. From the mouth of the Okanogan to Priests Rapids extends a superb canyon, with precipitous walls of black columnar basalt 1000 to 3000 ft. in height. The finest portion is below the Rock Island Rapids. In this part of its course, along the Cascade range in the Great Plain and at its passage of the range westward, rapids and cascades particularly obstruct the imperfectly opened bed. In the lower Columbia, navigation is first interrupted 160 m. from the mouth at the Cascades, a narrow gorge across the Cascade range 4.5 m. long, where the river falls 24 ft. in 2500; the rapids are evaded by a canal constructed (1878-1896) by the Federal government, and by a portage railway (1890-1891). Fifty-three miles above this are the Dalles, a series of falls, rapids and rock obstructions extending some 12 m. and ending at Celilo, 115m. below Wallula, with a fall of 20 ft. There are also impediments just below the mouth of the Snake; others in the lower course of this river below Riparia; and almost continuous obstructions in the Columbia above Priests Rapids. The commerce of the Columbia is very important, especially that from Portland, Vancouver, Astoria, and other outlets of the Willamette valley and the lower Columbia. The grain region of the Great Plain, the bottom-land orchards and grain field on the plateaus of the Snake, have not since 1880 been dependent upon the water navigation for freighting, but in their interest costly attempts have been made to open the river below the Snake uninterruptedly to commerce.
The Columbia is one of the greatest salmon streams of the world (seeOregon). The tonnage of deep-sea vessels in and out over the bar at the river’s mouth from 1890-1899 was 9,423,637 tons. From 1872-1899 the United States government expended for improvement of the Snake and Columbia $6,925,649. The mouth of the latter is the only deep-water harbour between San Francisco and Cape Flattery (700 m.), and the only fresh water harbour of the Pacific coast. To facilitate its entrance, which, owing to bars, tides, winds, and the great discharge of the river, has always been difficult, a great jetty has been constructed (1885-1895, later enlarged) to scour the bars. It was about 4.5 miles long, and in 1903 work was begun to make it 2.5 miles longer. The tides are perceptible 150 m. above the mouth (mean tide at Astoriac.6.2 ft.), the average tidal flow at the mouth being about 1,000,000 cub. ft. per second; while the fresh water outflow is from 90,000 to 300,000 cub. ft. according to the stage of water, and as high as 1,000,000 cub. ft. in time of flood. Improvements were undertaken by the Federal government and a state commission in 1902 in order to secure a 25-ft. channel from Portland to the sea.
In 1792, and possibly also in 1788, the river mouth was entered by Captain Robert Gray (1755-1806) of Boston, Mass., who named the river after his own vessel, “Columbia,†which name has wholly supplanted the earlier name, “Oregon.†In 1804-1805 the river was explored by Meriwether Lewis and William Clark. Upon these discoveries the United States primarily based its claim to the territory now embraced in the states of Oregon and Washington.
COLUMBIA UNIVERSITY,one of the oldest and most important of the higher institutions of learning in the United States, located for the most part on Morningside Heights, New York city. It embraces Columbia College, founded as King’s College in 1754; a school of medicine (the College of Physicians and Surgeons) founded in 1767, in West 59th Street; a school of law, founded in 1858; schools of applied science, including a school of mines and schools of chemistry and engineering, separately organized in 1896; a school of architecture, organized in 1881; graduate schools of political science, organized in 1880, philosophy, organized in 1890, and pure science, organized in 1892; and a school of journalism; closely affiliated with it are the College of Pharmacy, founded in 1829, in West 68th Street; Teachers’ College, founded in 1886, as the New York College for the Training of Teachers, and essentially a part of the university since 1899; and Barnard College (for women) founded in 1889, and essentially a part of the university since 1900. Reciprocal relations also exist between the university and both the General Theological Seminary of the Protestant Episcopal Church and the Union Theological Seminary, thus practically adding to the university a theological department. Columbia also nominates the American professors who lecture at German universities by the reciprocal arrangement made in 1905, the German professors lecturing in America being nominated by the Prussian ministry of education. Women are now admitted to all the university courses except those in law, medicine, technology and architecture. Since 1900 a summer session has been held for six weeks and attended largely by teachers. Teachers and others, under the direction of the Teachers’ College, are afforded an opportunity to pursue coursesin absentiaand so meet some of the requirements for an academic degree or a teacher’s diploma. All students of good ability are enabled to complete the requirements for the bachelor’s degree together with any one of the professional degrees by six years of study at the university. Several courses of lectures designed especially for the public—notably the Hewitt Lectures, in co-operation with Cooper Union—are delivered at different places in the city and at the university.
In 1908 there were in Columbia University in all departments 609 instructors and 4096 students; of these 420 were in Barnard College, 850 were in the Teachers’ College, and 229 were in the College of Pharmacy. The numerous University publicationsinclude works embodying the results of original research published by the University Press; “Studies†published in the form of a series by each of several departments, various periodicals edited by some members of the faculty, such as theColumbia University Quarterly, thePolitical Science Quarterly, and theSchool of Mines Quarterly; and several papers or periodicals published by the students, among which are theColumbia Spectator, a daily paper, theColumbia Law Review, theColumbia Monthlyand theColumbia Jester.
With two or three unimportant exceptions the buildings of the university on Morningside Heights have been erected since 1896. They include, besides the several department buildings, a library building, a university hall (with gymnasium), Earl Hall (for social purposes), St Paul’s chapel (dedicated in 1907), two residence halls for men, and one for women. The library contains about 450,000 volumes exclusive of duplicates and unbound pamphlets. The highest authority in the government of the institution is vested in a board of twenty-four trustees, vacancies in which are filled by co-optation; but the immediate educational interests are directed largely by the members of the university council, which is composed of the president of the university, the dean and one other representative from the faculty of each school. The institution is maintained by the proceeds from an endowment fund exceeding $15,000,000, by tuition fees ranging, according to the school, from $150 to $250 for each student, and by occasional gifts for particular objects.
The charter (1754) providing for the establishment of King’s College was so free from narrow sectarianism as to name ministers of five different denominations for ex-officio governors, and the purpose of the institution as set forth by its first president, Dr Samuel Johnson (1696-1772) was about as broad as that now realised. In 1756 the erection of the first building was begun at the lower end of Manhattan Island, near the Hudson, and the institution prospered from the beginning. From 1776 to 1784, during the War of Independence, the exercises of the college were suspended and the library and apparatus were stored in the New York city hall. In 1784 the name was changed to Columbia College, and an act of the legislature was passed for creating a state university, of which Columbia was to be the basis. But the plan was not a success, and three years later, in 1787, the act was repealed and the administration of Columbia was entrusted to a board of trustees of which the present board is a successor. In 1857 there was an extensive re-organization by which the scope of the institution was much enlarged, and at the same time it was removed to a new site on Madison Avenue between 49th and 50th Streets. From 1890 to 1895 much centralization in its administration was effected, in 1896 the name of Columbia University was adopted, and in the autumn of 1897 the old site and buildings were again abandoned for new, this time on Morningside Heights.
