These have, from the time of their discovery, been renowned among the Russian ivory collectors for their extraordinary richness in tusks and portions of skeletons of the extinct northern species of elephant known by the name ofmammoth.
We know by the careful researches of the academicians PALLAS, VON BAER, BRANDT, VON MIDDENDORFF, FR. SCHMIDT, &c., that the mammoth was a peculiar northern species of elephant with a covering of hair, which, at least during certain seasons of the year, lived under natural conditions closely resembling those which now prevail in middle and even in northern Siberia. The widely extended grassy plains and forests of North Asiawere the proper homeland of this animal, and there it must at one time have wandered about in large herds.
The same, or a closely allied species of elephant, also occurred in North America, in England, France, Switzerland, Germany, and North Russia. Indeed, even in Sweden and Finland inconsiderable mammoth remains have sometimes been found.[214]But while in Europe only some more or less inconsiderable remains of bones are commonly to be found, in Siberia we meet not only with whole skeletons, but also whole animals frozen in the earth, with solidified blood, flesh, hide, and hair. Hence we may draw the conclusion that the mammoth died out, speaking geologically, not so very long ago. This is besides confirmed by a remarkable antiquarian discovery made in France. Along with a number of roughly worked flint flakes, pieces of ivory were found, on which, among other things, a mammoth with trunk, tusks, and hair was engraved in rough but unmistakable lineaments, and in a style resembling that which distinguishes the Chukch drawings, copies of which will be found further on in this work. This drawing, whose genuineness appears to be proved, surpasses in age, perhaps a hundredfold, the oldest monuments that Egypt has to show, and forms a remarkable proof that the mammoth, the original of the drawing, lived in Western Europe contemporaneously with man. The mammoth remains are thus derived from a gigantic animal form, living in former times in nearly all the lands now civilized, and whose carcase is not yet everywhere completely decomposed. Hence the great and intense interest which attaches to all that concerns this wonderful animal.
If the interpretation of an obscure passage in Pliny be correct, mammoth ivory has, from the most ancient times, formed avalued article of commerce, which, however, was often mistaken for the ivory of living elephants and of the walrus. But portions of the skeleton of the mammoth itself are first described in detail by WITSEN, who during his stay in Russia in 1686 collected a large number of statements regarding it, and at least in the second edition of his work gives good drawings of the under jaw of a mammoth and the cranium of a fossil species of ox, whose bones are found along with the remains of the mammoth (WITSEN, 2nd. edit. p. 746). But it appears to have escaped Witsen, who himself considered mammoth bones to be the remains of ancient elephants, and who well knew the walrus, that in a number of the accounts which he quotes, the mammoth and the walrus are clearly mixed up together, which is not so wonderful, as both are found on the coast of the Polar Sea, and both yielded ivory to the stocks of the Siberian merchants. In the same way all the statements which the French Jesuit, AVRIL, during his stay in Moscow in 1686, collected regarding the amphibious animal,Behemoth, occurring on the coast of the Tartarian Sea, (Polar Sea) refer not to the mammoth, as some writers, HOWORTH[215]for example, have supposed, but to the walrus. The name mammoth, which is probably of Tartar origin, Witsen appears to wish to derive from Behemoth, spoken of in the fortieth chapter of the Book of Job. The first mammoth tusk was brought to England in 1611, by JOSIAS LOGAN. It was purchased in the region of the Petchora, and attracted great attention, as appears from Logan's remark in a letter to Hakluyt, that one would not have dreamed to find such wares in the region of the Petchora (Purchas, iii p. 546). As Englishmen at that time visited Moscow frequently, and for long periods, this remark appears to indicate that fossil ivory first became

known in the capital of Russia some time after the conquest of Siberia.

I have not, indeed, been successful during the voyage of theVegain making any remarkable discovery that would throw light on the mode of life of the mammoth,[216]but as we now sail forward between shores probably richer in such remains than any other on the surface of the globe, and over a sea, from whose bottom our dredge brought up, along with pieces of driftwood, half-decayed portions of mammoth tusks, and as the savages with whom we came in contact, several times offered us very fine mammoth tusks or tools made of mammoth ivory, it maynot perhaps be out of place here to give a brief account of some of the most important mammothfindswhich have been preserved for science. We can only refer to the discovery of mammothmummies,[217]for thefindsof mammoth tusks sufficiently well preserved to be used for carving are so frequent as to defy enumeration. Middendorff reckons the number of the tusks, which yearly come into the market, as at least a hundred pairs,[218]whence we may infer, that during the years that have elapsed since the conquest of Siberia useful tusks from more than 20,000 animals have been collected.
The discovery of a mammoth-mummyis mentioned for the first time in detail in the sketch of a journey which the Russian ambassador EVERT YSSBRANTS IDES, a Dutchman by birth, made in 1692 through Siberia to China. A person whom Yssbrants Ides had with him during his journey through Siberia, and who travelled every year to collect mammoth ivory, assured him that he had once found a head of this animal in a piece of frozen earth which had tumbled down. The flesh was putrefied, the neck-bone was still coloured by blood, and some distance from the head a frozen foot was found.[219]The foot was taken to Turuchansk, whence we may infer that thefindwas made on the Yenisej. Another time the same man found a pair of tusks weighing together twelve poods or nearly 200 kilogram. Ides' informant further stated, that while the heathen Yakuts, Tunguses,and Ostyaks, supposed that the mammoth always lived in the earth and went about in it, however hard the ground might be frozen, also that the large animal died when it came so far up that it saw or smelled the air; the old Russians living in Siberia were of opinion that the mammoth was an animal of the same kind as the elephant, though with tusks somewhat more bent and closer together; that before the Flood Siberia had been warmer than now, and elephants had then lived in numbers there; that they had been drowned in the Flood, and afterwards, when the climate became colder, had frozen in the river mud.[220]
The folk-lore of the natives regarding the mode of life of the mammoth under ground is given in still greater detail in J.B. MÜLLER'SLeben und Gewonheiten der Ostiaken unter dem Polo arctico wohnende, &c. Berlin, 1720 (in French inRecueil de Voiages au Nord, Amsterdam, 1731-38, Vol. VIII. p. 373). According to the accounts given by Muller, who lived in Siberia as a Swedish prisoner of war,[221]the tusks formed the animal's horns. With these, which were fastened above the eyes and were movable, the animal dug a way for itself through the clay and mud, but when it came to sandy soil, the sand ran together so that the mammoth stuck fast and perished. Muller further states, that many assured him that they themselves had seen such animals on the other side of Beresovsk in large grottos in the Ural mountains (loc. cit.p. 382).
KLAPROTH received a similar account of the mammoth's way of life from the Chinese in the Russo-Chinese frontier and trading town Kyachta. For mammoth ivory was considered to be tusks of the giant rattien-shu, which is only found in the coldregions along the coast of the Polar Sea, avoids the light, and lives in dark holes in the interior of the earth. Its flesh is said to be cooling and wholesome. Some Chinese literati considered that the discovery of these immense earth rats might even explain the origin of earthquakes.[222]
It was not until the latter half of the last century that a European scientific man had an opportunity of examining a similarfind. In the year 1771 a complete rhinoceros, with flesh and hide, was uncovered by a landslip on the river Wilui in 64° N.L. Its head and feet are still preserved at St. Petersburg. All the other parts were allowed to be destroyed for want of means of transport and preservation.[223]What was taken away showed that this primeval rhinoceros (Rhinoceros antiquitatisBlumenbach) had been covered with hair and differed from all now living species of the same family, though strongly resembling them in shape and size. Already, long before the horns of the fossil rhinoceros had attracted the attention of the natives, pieces of these horns were used for the same purposes for which the Chukches employ strips of whalebone, viz. to increase the elasticity of their bows. They were considered at the same time to exert a like beneficial influence on the arrow, tending to make it hit the mark, as, according to the hunter's superstition among ourselves in former days, some cat's claws and owl's eyes placed in the bullet mould had on the ball. The natives believed that the crania and horns of the rhinoceros found along with the remains of the mammoth belonged to

gigantic birds, regarding which there were told in the tents of the Yakut, the Ostyak and the Tunguse many tales resembling that of the bird Roc in theThousand and One Nights. Ermann and Middendorff even suppose that suchfindstwo thousand years ago gave occasion to Herodotus' account of the Arimaspi and the gold-guarding dragons (Herodotus, Book IV. chap. 27). Certain it is that during the middle ages such "grip-claws" were preserved, as of great value, in the treasuries and art collections of that time, and that they gave rise to many a romantic story in the folk-lore both of the West and East. Even inthis century Hedenström, the otherwise sagacious traveller on the Siberian Polar Sea, believed that the fossil rhinoceros' horns were actual, "grip-claws." For he mentions in his oft-quoted work, that he had seen such a claw 20 verschoks (0.9 metre) in length, and when he visited St. Petersburg in 1830, the scientific men there did not succeed in convincing him that his ideas on this subject were incorrect.[224]
A newfindof a mammothmummywas made in 1787, when the natives informed the Russian travellers SARYTSCHEV and MERK, that about 100 versts below the village Alasejsk, situated on the river Alasej running into the Polar Sea, a gigantic animal had been washed out of the sand beds of the beach in an upright posture, undamaged, with hide and hair. Thefind, however, does not appear to have been thoroughly examined.[225]
In 1799 a Tunguse found on the Tamut Peninsula, which juts out into the sea immediately south-east of the river-arm by which theLena, steamed up the river, another frozen-in mammoth. He waited patiently five years for the ground thawing so much as that the precious tusks should be uncovered. The softer parts of the animal accordingly were partly torn in pieces and destroyed by beasts of prey and dogs, when the place was closely examined in 1806 by ADAMS the Academician. Only the head and two of the feet were then almost undamaged. The skeleton, part of the hide, a large quantity of long hair and woolly hair a foot and a half long were taken away. How fresh the carcase was may be seen from the fact that parts of the eye could still be clearly distinguished. Similar remains had beenfound two years before, a little further beyond the mouth of the Lena, but they were neither examined nor removed.[226]
A newfindwas made in 1839, when a complete mammoth was uncovered by a landslip on the shore of a large lake to the west of the mouth of the Yenisej, seventy versts from the Polar Sea. It was originally almost entire, so that even the trunk appears to have been preserved, to judge by the statement of the natives that a black tongue as long as a month-old reindeer calf was hanging out of the mouth; but it had, when it was removed in 1842, by the care of the merchant TROFIMOV, been already much destroyed.[227]
Next after Trofimov's mammoth come the mammoth-findsof Middendorff and Schmidt. The former was made in 1843 on the bank of the river Tajmur, under 75° N.L.; the latter in 1866 or the Gydatundra, west of the mouth of the Yenisej in 70° 13' N.L. The soft parts of thesefindswere not so well preserved as those just mentioned. But thefindsat all events had a greater importance for science, from the localities having been thoroughly examined by competent scientific men. Middendorff arrived at the result that the animal found by him had floated from more southerly regions to the place where it was found. Schmidt on the other hand found that the stratum which contained the mammoth rested on a bed of marine clay, containing shells of high northern species of crustacea which still live in the Polar Sea, and that it was covered with strata of sand alternating with beds, from a quarter to half a foot thick, of decayed remains of plants, which completely correspond with the turf beds which are still formed in the lakes of thetundra. Even the very beds of earth and clay in which the bones, pieces ofhide, and hair of the mammothmummywere enclosed, contained pieces of larch, branches and leaves of the dwarf birch (Betulct nana), and of two northern species of willow (Salie glauca, andherbacea).[228]It appears from this that the climate of Siberia at the time when these mammoth-carcases were imbedded, was very nearly the same as the present, and as the stream in whose neighbourhood the find was made is a comparatively inconsiderabletundrariver, lying wholly to the north of the limit of trees, there is no probability that the carcase drifted with the spring ice from the wooded region of Siberia towards the north. Schmidt, therefore, supposes that the Siberian elephant, if it did not always live in the northernmost parts of Asia, occasionally wandered thither, in the same way that the reindeer now betakes itself to the coast of the Polar Sea. VON BRANDT, VON SCHMALHAUSEN, and others, had besides already shown that the remains of food which were found in the hollows of the teeth of the Wilui rhinoceros consisted of portions of leaves and needles of species of trees which still grow in Siberia.[229]
Soon after the mammoth found on the Gydatundrahad been examined by Schmidt, similarfindswere examined by GERHARD VON MAYDELL, at three different places between the rivers Kolyma and Indigirka, about a hundred kilometres from the Polar Sea. With respect to thesefindsI can only refer to a paper by L. VON SCHRENCK in theBulletinof the St. Petersburg Academy, T. XVI. 1871, p. 147.
Under the guidance of natives I collected in 1876 at the confluence of the river Mesenkin with, the Yenisej, in 71° 28' N.L., some fragments of bones and pieces of the hide of amammoth. The hide was 20 to 25 millimetres thick and nearly tanned by age, which ought not to appear wonderful, when we consider that, though the mammoth lived in one of the latest periods of the history of our globe, hundreds of thousands, perhaps millions of years have, however, passed since the animal died to which these pieces of skin once belonged. It was clear that they had been washed by the neighbouring river Mesenkin out of the tundra-bank, but I endeavoured, without success, to discover the original locality, which was probably already concealed by river mud. In the neighbourhood was found a very fine cranium of the musk ox.
A new and importantfindwas made in 1877 on a tributary of the Lena, in the circle Werchojansk, in 69° N.L. For there was found there an exceedingly well preserved carcase of a rhinoceros (Rhinoceros Merckii, Jaeg.), a different species from the Wilui rhinoceros examined by Pallas. However, before the carcase was washed away by the river, there had only been removed the hair-covered head and one foot.[230]From thefindSchrenck draws the conclusion that this rhinoceros belonged to a high-northern species, adapted to a cold climate, and living in, or at least occasionally wandering to, the regions where the carcase was found. There the mean temperature of the year is now very low,[231]the winter exceedingly cold (-63°.2 has been registered) and the short summer exceedingly warm. Nowhereon earth does the temperature show extremes so widely separated as here. Although the trees in winter often split with tremendous noise, and the ground is rent with the cold, the wood is luxuriant and extends to the neighbourhood of the Polar Sea, where besides, the winter is much milder than farther in the interior. With respect to the possibility of these large animals finding sufficient pasture in the regions in question, it ought not to be overlooked that in sheltered places overflowed by the spring inundations there are found, still far north of the limit of trees, luxuriant bushy thickets, whose newly-expanded juicy leaves, burned up by no tropical sun, perhaps form a special luxury for grass-eating animals, and thateven the bleakest stretches of land in the high north are fertile in comparison with many regions where at least the camel can find nourishment, for instance the east coast of the Red Sea.
The nearer we come to the coast of the Polar Sea, the more common are the remains of the mammoth, especially at places where there have been great landslips at the river banks when the ice breaks up in spring. Nowhere, however, are they found in such numbers as on the New Siberian Islands. Here Hedenström in the space of a verst saw ten tusks sticking out of the ground, and from a single sandbank on the west side of Liachoff's Island the ivory collectors had, when this traveller visited the spot, for eighty years made their best tusk harvest. That newfindsmay be made there year by year depends on the bones and tusks being washed by the waves out of the sandbeds on the shore, so that after an east wind which has lasted some time they may be collected at low water on the banks then laid dry. The tusks which are found on the coast of the Polar Sea are said to be smaller than those that are found farther south, a circumstance which possibly may be explained by supposing that, while the mammoth wandered about on the plains of Siberia, animals of different ages pastured in company, and that the younger of them, as being more agile andperhaps more troubled by flies than the older, went farther north than these.
Along with bones of the mammoth there are found on the New Siberian Islands, in not inconsiderable numbers, portions of the skeletons of other animal forms, little known, but naturally of immense importance for ascertaining the vertebrate fauna which lived at the same time with the mammoth on the plains of Siberia, and the New Siberian group of islands is not less remarkable for the "wood-hills," highly enigmatical as to their mode of formation, which Hedenström found on the south coast of the northernmost island. These hills are sixty-four metres high, and consist of thick horizontal sandstone beds alternating with strata of fissile bituminous tree stems, heaped on each other to the top of the hill. In the lower part of the hill the tree stems lie horizontally, but in the upper strata they stand upright, though perhaps not rootfast.[232]The flora and fauna of the island group besides are still completely unknown, and the fossils, among them ammonites with exquisite pearly lustre, which Hedenström brought home from the rock strata on Kotelnoj Island, hold out inducement to further researches, which ought to yield the geologist valuable information as to the former climate and the former distribution of land and sea on the surface of the globe. The knowledge of the hydrography of this region is besides an indispensable condition for judging of the state of the ice in the sea which washes the north coast of Asia. Here lies the single available starting-point for the exploration of the yet altogether unknown sea farther to the north, and from hills on the two northernmost islands Hedenström thought that across the sea to the north-west and north-east he saw obscure outlines of new land, on which no man had yet set his foot. All these circumstances confer on this group of islandsan uncommon interest in a scientific and geographical respect, and therefore no long time can elapse until a scientific expedition be sent to these regions. Just for this reason I now desired, as a preparation for a future voyage, to wander about here for a couple of days, partly on foot, partly by boat.
STOLBOVOJ ISLAND.STOLBOVOJ ISLAND.After a drawing by O. Nordquist.
The air was calm, but for the most part clouded, the temperature as high as +4°, the sea clear of ice, the salinity of the water 1.8 per cent, with a temperature of +2° to +3°. At first we made rapid progress, but after having in the afternoon of the 28th August sighted the westernmost islands, Semenoffskoj and Stolbovoj, the sea became so shallow that for long stretches we were compelled to sail in six to seven metres water. Some very rotten ice, or rather ice sludge, was also met with, which compelled us to make tediousdétours, and prevented theVegafrom going at full speed.The animal life was among the scantiest I had seen during my many travels in the Polar Seas. A few seals were visible. Of birds we saw some terns and gulls, and even far out at sea a pretty large number of phalaropes—the most common kind of bird on the coast of the Asiatic Polar Sea, at least in autumn. Stolbovoj Island was, especially on the north side, high with precipitous shore-cliffs which afforded splendid breeding-places for looms, black guillemots and gulls. At all such cliffs there breed on Spitzbergen millions of sea fowl, which are met with out on the surrounding sea in great flocks searching for their food. Here not a single loom was seen, and even the number of the gulls was small, which indeed in some degree was to be accounted for by the late season of the year, but also by the circumstance that no colony of birds had settled on the rocky shores of the island.
The sea bottom consisted at certain places of hard packed sand, or rather, as I shall endeavour to show farther on, offrozensand, from which the trawl net brought up no animals. At other places there was found a clay, exceedingly rich inIdothea entomonandSabineiand an extraordinary mass of bryozoa, resembling collections of the eggs of mollusca.
It was not until the 30th of August that we were off the west side of Ljachoff's Island, on which I intended to land. The north coast, and, as it appeared the day after, the east coast was clear, of ice, but the winds recently prevailing had heaped a mass of rotten ice on the west coast. The sea besides was so shallow here, that already at a distance 15' from land we had a depth of only eight metres. The ice heaped against the west coast of the island did not indeed form any very serious obstacle to the advance of theVega, but in case we had attempted to land there it might have been inconvenient enough, when the considerable distance between the vessel and the land was to be traversed in a boat or the steam launch, and it might even, if a sudden frost had occurred, have become a fetter, which wouldhave confined us to that spot for the winter. Even a storm arising hastily might in this shallow water have been actually dangerous to the vessel anchored in an open road. The prospect of wandering about for some days on the island did not appear to me to outweigh the danger of the possible failure of the main object of the expedition. I therefore gave up for the time

my intention of landing. The course was shaped southwards towards the sound, of so bad repute in the history of the Siberian Polar Sea, which separates Ljachoff's Island from the mainland.

So far as we could judge at a distance from the appearance of the rocks, Stolbovoj consisted of stratified rocks, Ljachoff's Island, on the contrary, like the mainland opposite, of high hills, much shattered, probably formed of Plutonic stone-masses.Between these there are extensive plains, which, according to a statement by the land surveyor CHVOINOFF, who by order of the Czar visited the island in 1775, are formed of ice and sand, in which lie imbedded enormous masses of the bones and tusks of the mammoth, mixed with the horns and skulls of some kind of ox and with rhinoceros' horns. Bones of the whale and walrus are not mentioned as occurring there, but "long small screw-formed bones," by which are probably meant the tusks of the narwhal.[233]
All was now clear of snow, with the exception of a few of the deeper clefts between the mountains. No traces of glaciers were visible, not even such small collections of ice as are to be found everywhere on Spitzbergen where the land rises a few hundred feet above the surface of the sea. Nor, to judge by the appearance of the hills, have there been any glaciers in former times, and this is certainly the case on the mainland. The northernmost part of Asia in that case has never been covered by such an ice-sheet as is assumed by the supporters of a general ice age embracing the whole globe.
The large island right opposite to Svjatoinos was discovered in 1770 by LJACHOFF, whose name the island now bears. In 1788 Billings' private secretary, MARTIN SAUER, met with Ljachoff at Yakutsk, but he was then old and infirm, on which account, when Sauer requested information regarding the islands in the Polar Sea, he referred him to one of his companions, ZAITAI PROTODIAKONOFF. He informed him that the discovery was occasioned by an enormous herd of reindeer which Ljachoff, in the month of April 1770, saw going fromSvjatoinos towards the south, and whose track came over the ice from the north. On the correct supposition that the reindeer came from some land lying to the north, Ljachoff followed the track in a dog-sledge, and thus discovered the two most southerly of the New Siberian Islands, a discovery which was rewarded by the Czarina Catherine II. with the exclusive right to hunt and collect ivory on them.[234]
LJACHOFF'S ISLAND.LJACHOFF'S ISLAND.After a drawing by O. Nordquist.
Ljachoff states the breadth of the sound between the mainland and the nearest large island at 70 versts or 40'. On Wrangel's map again the breadth is not quite 30'. On themainland side it is bounded by a rocky headland projecting far into the sea, which often formed the turning point in attempts to penetrate eastwards from the mouth of the river Lena, and perhaps just on that account, like many other headlands dangerous to the navigator on the north coast of Russia, was calledSvjatoinos(the holy cape), a name which for the oldest Russian Polar Sea navigators appears to have had the same signification as "the cape that can be passed with difficulty." No one however now thinks with any apprehension of the two "holy capes," which in former times limited the voyages of the Russians and Fins living on the White Sea to the east and west, and this, I am quite convinced, will some time be the case with this and all other holy capes in the Siberian Polar Sea.
The sea water in the sound was much mixed with river water and had a comparatively high temperature, even at a depth of nine to eleven metres. The animal life at the sea bottom was poor in species but rich in individuals, consisting principally ofIdothea entomon, of which Dr. Stuxberg counted 800 specimens from a single sweep of the dredge. There were obtained at the same time, besides a few specimens ofIdothea Sabinei, sponges and bryozoa in great abundance, and small mussels, crustacea, vermes, &c. Various fishes were also caught, and some small algæ collected. The trawl-net besides brought up from the bottom some fragments of mammoth tusks, and a large number of pieces of wood, for the most part sticks or branches, which appear to have stood upright in the clay, to judge from the fact that one of their ends was often covered with living bryozoa. These sticks often caused great inconvenience to the dredgers, by tearing the net that was being dragged along the bottom.
On the night preceding the 31st of August, as we steamed past Svjatoinos, a peculiar phenomenon was observed. The sky was clear in the zenith and in the east; in the west, on the other hand, there was a bluish-grey bank of cloud. The temperature of the water near the surface varied between +1° and +1°.6,that of the air on the vessel between +1°.5 and +1°.8. Although thus both the air and the water had a temperature somewhat above the freezing-point, ice was seen to form on the calm, mirror-bright surface of the sea. This ice consisted partly of needles, partly of a thin sheet. I have previously on several occasions observed in the Arctic seas a similar phenomenon, that is to say, have observed the formation of ice when the temperature of the air was above the freezing-point. On this occasion, when the temperature of the uppermost stratum of water was also above the freezing-point, the formation of ice was clearly a sort of hoar-frost phenomenon, caused by radiation of heat, perhaps both upwards towards the atmosphere and downwards towards the bottom layer of water, cooled below the freezing-point.
The whole day we continued our voyage eastwards with glorious weather over a smooth ice-free sea, and in the same way on the 1st September, with a gentle southerly wind, the temperature of the air at noon in the shade being +5°.6. On the night before the 2nd September the wind became northerly and the temperature of the air sank to -1°. Little land was seen, though we were still not very far from the coast. Near to it there was a broad ice-free, or nearly ice-free, channel, but farther out to sea ice commenced. The following night snow fell, so that the whole of the deck and the Bear Islands, which we reached on the 3rd September, were sprinkled with it.
Hitherto, during the whole time we sailedalong the coast, we had scarcely met with any fields of drift-ice but such as were formed of rotten, even, thin and scattered pieces of ice, in many places almost converted into ice-sludge, without an "ice-foot" and often dirty on the surface. No iceberg had been seen, nor any large glacier ice-blocks, such as on the coasts of Spitzbergen replace the Greenland icebergs. But east of Svjatoinos the ice began to increase in size and assume the same appearance as the ice north of Spitzbergen. It was here, besides, less dirty, andrested on a hard ice-foot projecting deep under water and treacherous for the navigator.
The ice of the Polar Sea may be divided into the following varieties:—
1.Icebergs. The true icebergs have a height above the surface of the water rising to 100 metres. They often ground in a depth of 200 to 300 metres, and have thus sometimes a cross section of up to 400, perhaps 500 metres. Their area may amount to several square kilometres. Such enormous blocks of ice are projected into the North Polar Sea only from the glaciers of Greenland, and according to Payer's statement, from those of Franz-Josef Land also; but not, as some authors (GEIKIE, BROWN, and others) appear to assume and have shown by incorrect ideal drawings, from glaciers which project into the sea and there terminate with a perpendicular evenly-cut border, but from very uneven glaciers which always enter the sea in the bottoms of deep fjords, and are split up into icebergs long before they reach it. It is desirable that those who write on the origin of icebergs, should take into consideration the fact that icebergs are only formed at places where a violent motion takes place in the mass of the ice, which again within a comparatively short time results in the excavation of the deep ice-fjord. The largest iceberg, which, so far as I know, has beenmeasuredin that part of the Polar Sea which lies between Spitzbergen and Wrangel Land, is one which Barents saw at Cape Nassau on the 17/7th August 1596. It was sixteen fathoms high, and had grounded in a depth of thirty-six fathoms. In the South Polar Sea icebergs occur in great numbers and of enormous size. If we may assume that they have an origin similar to those of Greenland, it is probable that round the South Pole there is an extensive continent indented by deep fjords.
2.Glacier Ice-blocks. These, which indeed have often been called icebergs, are distinguished from true icebergs not only by their size, but also by the way in which they are formed.They have seldom a cross section of more than thirty or forty metres, and it is only exceptionally that they are more than ten metres high above the surface of the water. They originate from the "calving" of glaciers which project into the sea with a straight and evenly high precipitous border. Such glaciers occur in large numbers on the coasts of Spitzbergen, and they are there of the same height as similar evenly-cut glaciers on Greenland. According to the statement of the Dane PETERSEN, who took part both in KANE'S expedition in 1853-55 and in Torell's in 1861, the glaciers, for instance, at Hinloopen Strait in Spitzbergen, are fully equal, with respect to their size and the height of their borders above the sea-level, to the enormous and much bewritten Humboldt glacier in Greenland. In Spitzbergen too we find at two places miniatures of the Greenland ice-currents, for instance the glacier which filled the North Haven in Bell Sound, another glacier which filled an old Dutch whaling haven between Recherche Bay and Van Keulen Bay, a glacier on the north side of Wablenberg Bay and perhaps at that part of the inland ice marked in my map of the expedition of 1872 as a bay on the east coast of North-east Land. It is even possible that small icebergs may be projected from the last-mentioned place, and thence drift out into the sea on the east coast of Spitzbergen.
Glacier-ice shows a great disposition to fall asunder into smaller pieces without any perceptible cause. It is full of cavities, containing compressed air, which, when the ice melts, bursts its attenuated envelope with a crackling sound like that of the electric spark. It thus behaves in this respect in the same way as some mineral salts which dissolve in water with slight explosions. Barents relates that on the 20/10th August 1596 he anchored his vessel to a block of ice which was aground on the coast of Novaya Zemlya. Suddenly, and without any perceptible cause, the rock of ice burst asunder into hundreds of smaller pieces with a tremendous noise, and to the great terror of all themen on board. Similar occurrences on a smaller scale I have myself witnessed. The cause to which they are due appears to me to be the following. The ice-block while part of the glacier is exposed to very severe pressure, which ceases when it falls into the sea. The pressure now in most cases equalises itself without any bursting asunder, but it sometimes happens that the inner strongly compressed portions of the ice-block cannot, although the pressure has ceased, expand freely in consequence of the continuous ice-envelope by which they are still surrounded. A powerful internal tension must thereby arise in the whole mass, which finally leads to its bursting into a thousand pieces. We have here a Prince Rupert's drop, but one whose diameter may rise to fifty metres, and which consists not of glass but of ice.
Glacier ice-blocks occur abundantly on the coasts of Spitzbergen and north Novaya Zemlya, but appear to be wanting or exceedingly rare along the whole north coast of Asia, between Yugor Schar and Wrangel Land. East of this they again occur, but not in any great numbers. This appears to show that the Western Siberian Polar Sea is not surrounded by any glacial lands. The glacier ice is commonly of a blue colour. When melted it yields a pure water, free of salt. Sometimes however it gives traces of salt, which are derived from the spray which the storms have carried high up on the surface of the glacier.
3. Pieces of ice from the ice-foot formed along the sea beach or the banks of rivers. They rise sometimes five or six metres above the surface of the water. They consist commonly of dirty ice, mixed with earth.
4.River Ice, level, comparatively small ice fields, which, when they reach the sea, are already so rotten that they soon melt away and disappear.
5. The walrus-hunters'Bay Ice; by which we understand level ice-fields formed in fjords and bays along the coast, and whichhave there been exposed to a comparatively early summer heat. The bay ice therefore melts away completely during summer, and it is not commonly much pressed together. When all the snow upon it has disappeared, there is to be seen above the surface of the water a little ice of the same colour as the water, while under water very considerable portions of unmelted hard ice are still remaining. This has given rise to the walrus-hunters' statement, which has been warmly maintained, that the ice in autumn finally disappears by sinking. Nearly all the ice we met with in the course of our voyage belonged to this variety.
6.Sea Ice, or heavy ice, which often exhibits traces of having been much pressed together, but has not been exposed to any early summer heat. The walrus-hunters call it sea ice, wishing, I imagine, to indicate thereby that it is formed in the sea farther up towards the north. That it has drifted down from the north is indeed correct, but that it has been formed far from land over a considerable depth in the open sea is perhaps uncertain, as the ice that is formed there cannot, we think, be very thick. It has rather perhaps drifted down from the neighbourhood of some yet unknown Polar continent. Of this ice are formed most of the ice-fields in the seas east of Greenland, north of Spitzbergen, between Spitzbergen and the north island of Novaya Zemlya, and north of Behring's Straits. In the northern seas it does not melt completely during the summer, and remains of sea ice therefore often enter as component parts into the bay ice formed during the following winter. The latter then becomes rough and uneven, from remnants of old sea ice being frozen into the newly formed ice. Sea ice is often pressed together so as to form greattorossesor ice-casts, formed of pieces of ice which at first are angular and piled loose on each other, but gradually become rounded, and freeze together into enormous blocks of ice, which, together with the glacier ice-blocks, form the principal massof the ground ice found on the coasts of the Polar lands. The water which is obtained by melting sea-ice is not completely free from salt, but the older it is the less salt does it contain.
East of the Bear Islands heavy sea-ice in pretty compact masses had drifted down towards the coast, but still left an open ice-free channel along the land. Here the higher animal world was exceedingly poor, which, as far as the avi-fauna was concerned, must be in some degree ascribed to the late season of the year. For Wrangel mentions a cliff at the Bear Islands which was covered with numberless birds' nests. He saw besides, on the largest of these islands, traces of the bear, wolf, fox, lemming, and reindeer (Wrangel'sReise, i. pp. 304 and 327). Now the surrounding sea was completely deserted. No Polar bear saluted us from the ice-floes, no walruses, and only very few seals were visible. During many watches not a single natatory bird was seen. Only the phalarope was still met with in large numbers, even pretty far out at sea. Perhaps it was then migrating from the north. The lower animal world was more abundant. From the surface of the sea the drag-net brought up various small surface crustacea, inconsiderable in themselves, but important as food for larger animals; and from the sea-bottom were obtained a large number of the same animal forms as from the sound at Svjatoinos, and in addition some beautiful asterids and a multitude of very large beaker sponges.
On the 3rd September, after we had sailed past the Bear Islands, the course was shaped right for Cape Chelagskoj. This course, as will be seen by a glance at the map, carried us far from the coast, and thus out of the channel next the land, in which we had hitherto sailed. The ice was heavy and close, although at first so distributed that it was navigable. But with a north wind, which began to blow on the night before the 1st September, the temperature fell below the freezing-point, and the water between the pieces of drift-ice was covered with avery thick crust of ice, and the drift-ice came closer and closer together. It thus became impossible to continue the course which we had taken. We therefore turned towards the land, and at 6 o'clock P.M., after various bends in the ice and a few concussions against the pieces of ice that barred our way, again reached the ice-free channel, eight to twelve kilometres broad, next the land. While we lay a little way in among the drift-ice fields we could see no sign of open water, but it appeared as if the compact ice extended all the way to land, a circumstance which shows how careful the navigator ought to be in expressing an opinion as to the nature of thepackbeyond the immediate neighbourhood of the vessel. The temperature of the air, which in the ice-field had sunk to -3°, now rose at once to + 4°.1, while that of the water rose from -1°.2 to +3°.5, and its salinity fell from 2.4 to 13 per cent. All showed that we had now come into the current of the Kolyma, which from
