Northern Africa is a country of great mineral wealth, but it has been only slightly developed. The Moors, Berbers, Arabs, and other inhabitants of that region have never been famous for their mining industry. They have very little knowledge of geology, and understand the working of only a few metals. Most of the gold and silver which they make into filigree and other jewelry comes from Europe; in fact, they have no mines of these metals that are worth mentioning, and when their supply from Europe has been cut off by war or for other reasons, they were obliged to bring it by a long journey from Timbuctoo and other points to the South. The Moors that occupied Spain took back with them, at the time of their expulsion, a knowledge of mining, but they seem to have lost it almost completely in the course of two or three generations.
Among the native people of Northern Africa, the Kabyles, in Algeria, seem to possess more mining knowledge than any other tribe. They have been quite industrious in working the iron mines which abound in their country, and many of their processes display considerable ingenuity. They are excellent workers in iron and steel, and some of their knives, sword-blades, and other tools and weapons, are of a fine quality, and admit of a high polish and finish. Their gun-barrels have long been famous throughout Africa, and the terrible executionof which they are capable has been practically demonstrated on many battle-fields.
Down to 1830, with the exception of an occasional brief period, no part of Northern Africa had been occupied by any European power. Spain had several times occupied small portions of Morocco and Algeria, and the English and French had shown their force by descents upon the coast, but none of these changes had more than a few years’ duration. But in 1830, a new state of affairs began.
FRENCH ARMIES INVADE EGYPT.
France was exasperated by the depredations of Algerine pirates and the perfidy of the Bey of Algiers. She sent an expedition, which landed a few miles from Algiers, and in less than a fortnight the Bey was a prisoner on his way into exile, and his city, with an immense accumulation of treasure, fell into the hands of the invaders.
The French went to Algeria to stay, and they have carried out their intention. They sent their armies to overrun and occupy the country, and for years kept up an energetic warfare, until the Arabs were conquered. There have been occasional insurrections, some of them of considerable magnitude, but all have been unsuccessful, and there is at present no power in Algeria which can drive out the French. They have created harbors, have opened railways, have made hundreds of miles of wagon-roads, have introduced new modes of agriculture, planted forests, and taken many other means necessary to a permanent occupation. The country is progressing rapidly, and at present few of the wealthy and prosperous Arabs would be willing to exchange the new state of affairs for the old. There are many natives who would like to see the French expelled, but they are not among the most influential classes.
One of the first things which attracted the attention of the French, was the question of mining. In the very first year of their occupation, a geological survey of the country was ordered, and a corps of engineers was sent from France for that purpose.
Their report was of the most favorable character. They found copper, lead, silver, zinc, mercury—bath cinnabar, andsulphide—and in several places they discovered gold, but not in paying quantities. Many concessions for working these mines have been granted; some of them have been profitable, while others have been the reverse, owing chiefly to the lack of means of transportation. The steady increase in the number of railways and wagon-roads is doing much toward the development of these mines, and rendering profitable the working of those which have thus far been managed at a loss.
EXPLORATIONS OF THE IRON MINES.
But the greatest mineral wealth of Algeria is in its iron mines, which abound all along the coast, and so near to it that the matter of transportation is of no great consequence. The ore is of a remarkably good quality, as it contains very little sulphur, arsenic, and phosphorus, which frequently render otherwise valuable material almost worthless. Much of it contains a great deal of manganese, which is very useful in smelting and reducing the metal, and renders it unnecessary to supply that article in making the flux. The ore is so rich that it pays to transport it to England, even though it comes in competition with the iron ores of that country.
The principal use of this Algerian iron is for manufacture into Bessemer steel, and it is said to be vastly superior to all other iron for this purpose. The advance in iron and steel in the past few years has been greatly to the advantage of the iron miners in Algeria, and the most of them are making their fortunes with great rapidity.
One of the richest mines in the country is near Bone, in the Province of Constantine. During a journey through Algeria, I paid a visit to that place, and embraced the opportunity to investigate the iron question.
The mine is nothing more or less than a mountain of iron. It is known in Arabic asMoktu-el-Hadid, and was worked very slightly by the Kabyles, previous to the French occupation. The place is nineteen miles from Bone, and a railway connects the mine with the harbor. It is so arranged that the ore, which is piled into the cars at the mine, can be dumped into the holds of the ships in the harbor.
At first glance, you would not suppose this mountain to be ofany special value. It looks not unlike the famous Iron Mountain of Missouri, but is more irregular, and is not covered in the same way with trees and bushes. But as you examine closer, you see that the mountain is no common affair.
DESCRIPTION OF THE VALUE OF THE MINES.
In some places, the mineral crops up above the surface of the ground, and all that is necessary is to blast it away and cart it off. In other places, it appears in veins which are always very thick, and in a slanting position; they rest upon beds of mica-schist, and are covered with a layer of indurated clay, mingled with nodules of iron ore. The ore contains sixty-four per cent. of pure iron; the annual exportation is about half a million tons, and sometimes exceeds that amount. The profit, clear and clean after deducting every thing, is about half a million dollars, or one dollar on each ton of ore taken out. The owners of the mine have a valuable property, and are not inclined to sell it, or to take in partners.
There are other iron mines in Algeria, but none of them are so large or so profitable as the one I have just described. The labor is performed partly by Arab workmen, and partly by Frenchmen. The Arabs are very largely employed, and are quite industrious and reliable. The Kabyles are considered the best and can generally command a trifle more wages than the men of the other tribes for the same work. They come to the cities in search of employment, and after accumulating a certain sum of money, return home contented. Their wants are few, and they live very cheaply.
While I was in Algeria, I made a journey south to the Desert of Sahara. In the desert proper no mines of iron, gold, or silver are to be found, but there are some curious mines of salt, which have been known to the Arabs for thousands of years.
One day the guide called the attention of my companion and myself to a mountain of a peculiar bluish appearance, unlike those that surrounded it. Like all the other mountains in the desert, it had not a particle of vegetation upon it, and we could see no difference between that and the rest, except in its color. I asked what it was.
“It is the famous mountain of salt,” said the guide.
HOW THE ARABS OBTAIN THEIR SALT.
This information caused us to look again, and more intently. Herodotus, the Greek historian, who flourished more than two thousand years ago, traveled through this country, and describes five mountains of salt. This which was before us was one of the five.
As we came nearer, we could see that it presented a rough and broken surface, and had evidently been thrown up by some violent convulsion of the earth. That it is the result of an upheaval, is shown by the presence, at the top, of certain layers of sand and marine shells which are found lower down in the plain.
The salt stands in pillars and columns, and in great masses many tons in weight. Salt enough to pickle all the beef in the world could be obtained from this mountain, and then there would be enough left for the preservation of the mutton, pork, and other meats that need the aid of strong brine to keep them properly, and even then there would be a great deal of salt to spare.
During the winter, the rain loosens the blocks and causes crevices to form in the mass of salt rock. The Arabs go there in the spring and break away these blocks by the aid of iron bars; then they knock them to pieces with large hammers, and thus get them into proper shape for transportation. For thousands of years, they have thus been at work on this mountain, taking all they want, but the supply is not by any means exhausted. The quarries are not constantly worked, as the demand for the salt is not very great. The mountain is so far from the coast that it does not pay to carry the salt there, and consequently the demand is purely local.
There is a similar mountain, though much smaller, some distance away to the west. It is more curious in some respects, there being a stream of water which passes it, and has worn a great many pits, caverns, and cavities in the mass of salt. Before reaching the rock, the stream is perfectly fresh, but very soon it becomes impregnated with salt. The stalactites and pillars are very curious in their formation, and when the sun shines upon them they sparkle like great massesof diamonds. In some places, the crystals of salt jut over the edge of the little stream, and occasionally they fall just a little short of forming an arch.
THE FRENCH SUPPLY THE DESERT WITH WATER.
In the desert proper, the French have done something to advance growth by boring Artesian wells. The great need of the desert is water, and many thousands of square miles of land, on which there is not a blade of grass or plant, might be rendered fertile if any means could be devised to supply them with water. The French have given a great deal of study to this subject, but as none of them are possessed of the power of Moses to bring water from a rock where apparently none existed, they have not yet covered the desert with palm trees and wheat fields.
The palm tree must have water to keep it alive. The Arabs say it lives with its head in the fire and its foot in the water; it seems to be happy with the burning sun of the desert, and not even the hottest rays which the heavens can pour down can disturb it in the least so long as its foot is properly bathed. Take away its supply of water, and it dies in a short time. It must be watered twice a week; there is generally a ditch around the foot of the tree, and this ditch is filled either from a canal or with water carried in buckets or skins. About a barrel full of the liquid is needed for each tree.
It will thus be seen that the limit of a palm oasis in the desert may be sometimes determined by the water supply. I have seen thousands of acres of desert land, possessing no value whatever, which would have been far different had there been a running and reliable stream or spring in their vicinity.
The French determined to improve the supply of water, and in this way increase the value of the country both to themselves and the Arabs. The first attempt was made at the oasis of Tuggurt, in 1856. The apparatus was taken there on camels’ backs, with a great deal of trouble, and finally set at work.
After five weeks of labor the drill struck a water course under the gypsum, at a depth of about two hundred feet. An immense spring gushed out with such force that very littlestrength was required for removing the tools. It flowed about a thousand gallons a minute, and has been flowing at that rate ever since.
The natives were wild with delight. They danced and sung, and made a great many manifestations of joy, not only on the occasion of opening the well, but for days and weeks afterwards. Ever since then, similar scenes have been enacted in other parts of the desert occupied by the French, whenever a well is opened. The culture of dates has been enormously extended by the planting of new groves wherever the wells are made, and both the natives and their conquerors have found the enterprise of mutual advantage. Sometimes the wells are salt or brackish, but the date palm does not mind any little trifle like that. Whether the water which is supplied to it is fresh or salt, hot or cold, does not seem to make any difference to the tree. It prospers and grows and produces fruit all the same.
INLAND LAKE IN THE DESERT.
A part of the desert is below the level of the Mediterranean, and some of the scientific men and others interested in the development of Algeria, have proposed to dig a canal from the sea, and allow this empty space to be filled. They would thus create an inland lake on which steamers could run, and which could furnish a vast supply of water to groves of palm trees along its shores. But the enterprise is not likely to be undertaken, for a variety of reasons.
In the first place, the cost would be something enormous, and quite out of proportion to the result proposed. The cutting or canal would be more than a hundred miles long, and for quite a distance, forty or fifty feet deep.
The distance which could be flooded is variously estimated from twenty to forty thousand square miles. Of course the land covered by the water would be of no use, and it includes many prosperous oases of date palms, which would have far more water than they need in order to bear fruits. To start with, there would thus be a heavy loss.
The effect upon the climate of Europe of the proposed inland sea has been much discussed. The whole of France owes itswarm, genial climate to the hot winds which blow from Africa across the Mediterranean, and do not lose their soothing temperature till they reach the North Sea and the Baltic. Africa thus becomes a vast furnace to supply Europe with hot air. It is feared by many of the scientific men who have studied the matter, that the inland sea would partially or completely change the climate. The winds would absorb the moisture, and thus form vast rain clouds; instead of conveying warmth and dry air to southern Europe, they would be cool and laden with rain. The grapes would decay upon the vines without ripening; sunny France would be no longer so, and Paris would become as cold as Berlin, and as dreary as London. Doubtless this is an overstatement of the case, but the risk that any of these events might happen outweighs the probable good which the inland sea might accomplish.
THE SUEZ CANAL.
Not altogether distinct from mining matters, as it certainly required a vast deal of excavating, is the Suez Canal—a French enterprise of the greatest magnitude. The plan for making a canal between the Mediterranean and Red seas is very old, and has received a great deal of attention from ancient times to the present. One important difference between the canal of to-day and those of the olden time is in its direct course from sea to sea, which makes it altogether a salt-water canal. The old plans were in favor of tapping the Nile and connecting the river with the Red Sea, so that a portion of the route would be a fresh-water one. The size of modern ships rendered it necessary to abandon the Nile scheme altogether, as the shallowness of the river would not permit the passage of the ordinary sea-going vessel, even if we leave unconsidered those vast specimens of the naval architect’s skill which are the pride and boast of all maritime nations.
According to Herodotus and other writers, “the first to attempt the construction of the canal to the Red Sea,” was Pharaoh Necho II, one of the Egyptian kings, who reigned about six hundred and ten years before Christ. His canal left the Nile at Bubastis, near Zagazig, and followed along a valley leading toward the Red Sea, which then extended much fartherinland than it does at present. Pliny estimates the length of this canal at sixty-two Roman miles, or fifty-seven English ones, and modern measurements show that these figures were very nearly correct. Herodotus estimates the distance from the Red Sea to the mouth of the Nile at one hundred and fourteen miles, and he says that 120,000 men perished while cutting it. This is probably an exaggeration or a slip of the pen, as he doubtless meant to say that that number of men was engaged in the work.
The canal was not finished during the reign of Necho II. The work was continued by his successors, and finally completed, but it was neglected, and the drifting sands soon filled the canal and made it useless. It remained so for centuries, though several attempts were made to clear it out. It is said to have been re-opened about the year 1000 of our era, by one of the Arab sultans, but it was again neglected, with the same result as before.
PLAN OF NAPOLEON FOR DIGGING A CANAL.
In modern times, the first to take up the subject and give it careful attention, was the emperor Napoleon, at the time of his conquest of Egypt in 1798. He personally examined the traces of the canal made by Necho and his successors, and ordered one of his engineers to make a careful survey of the route, to ascertain what difference there might be between the levels of the two seas.
This engineer reported a difference of thirty feet, and as this would render it impossible to make a direct canal without locks, a scheme was projected for making use of a portion of the Nile, as in the olden time, and having a system of locks where the salt-water canal joined the river. But the chances of war interfered, as the French were compelled to evacuate Egypt before the plan had been reported.
Nothing more was done until 1846, when a mixed commission was appointed to investigate the matter. They exploded the old error of a difference of level, and showed that the height of the water on each side was so nearly the same as to make no appreciable difference. Further than to establish this fact, the commission did not go, except to draw up some elaborate plans, which never amounted to anything.
HOW THE CANAL WAS PLANNED AND DUG.
In 1855, a project was completed by M. de Lesseps, for a canal without locks, and this is the scheme which has been successfully carried out by the Suez Canal Company. Some of the details were changed, but none of them are of any serious consequence.
It would require too much space to record all the diplomatic and other negotiations that attended the inception of the scheme, and the various means adopted to secure the funds necessary for conducting the work. The financial part of it was quite as difficult as the labor of the engineers, and several times it looked as though the enterprise must be abandoned altogether. The whole capital required by the canal, from commencement to completion, was about seventeen million pounds sterling, or eighty-five millions of dollars!
The work of excavating was begun on the 25th of April, 1859, by a few laborers who dug a small ditch in the presence of M. de Lesseps and four directors of the company, on the spot selected for the Mediterranean mouth of the canal. Immediately after this working, encampments were established all along the line, and the enterprise was earnestly pushed. At first, the work was performed without any machinery. Men and donkeys were the active force, the former armed with shovels, and the latter having a couple of baskets hung across their backs.
A native would fill the baskets with sand and drive the donkey on. They proceeded to where the burden was to be deposited, and when they arrived there, the baskets were emptied, and the donkey was driven back for a fresh load.
But it was found that the removal from agriculture and their other usual employments of the men necessary for digging the canal, was a serious interference with the affairs of the country. Twenty thousand men were required every month, and the drain was found to be so great that, in 1863, the Khedive refused to furnish them.
Matters then came to a stand still, and the company set about replacing manual labor with machinery. Various machines were devised before success was reached, and the magnificent dredges were made, by which the canal was finished.What was at first thought to be a misfortune proved an advantage, as the dredges were far more economical than manual labor, and enabled the company to finish the work much sooner than would have been possible under the old plan.
THE FINISHING OF THE CANAL.
The canal was finished in the latter part of 1869, and opened for traffic on the 17th of November of that year. Forty-eight ships went from Port Said to Suez, on that day and the next, carrying guests who had been invited to the ceremonies. All nations of the world may be said to have taken part in the affair, which was on a magnificent scale, and cost many thousands of dollars to the Khedive of Egypt and the canal company. When the ceremonies were over, the canal was formally opened for business, and has been open ever since.
The canal is a hundred miles long from Suez to Port Said. The following figures of its dimensions will be found interesting:
At frequent intervals there are wide spaces where ships may pass, and there are three lakes which were formed by the filling of depressions in the desert. These lakes are pretty sheets of water, and one of them—Lake Timsah—has become a pleasure resort where the people of Cairo go to enjoy salt-water bathing.
The advantages of the canal to the commerce of the world are very great. The old routes have been partially abandoned for the new one, and at present the movement of steamers through the canal averages more than a hundred a month each way, not to speak of sailing ships and smaller craft. The saving of distance by the canal may be shown by the following table.
