But a greater project is agitating the minds of the forward Colonial party, the linking of the French possessions by a Trans-Saharian railway. The scheme is not a new one. It was much discussed thirty years ago. The French Government appointed a scientific commission to study the matter, and the French public, ever ready to support a vast engineering scheme, was eager to subscribe the necessary capital. The murder by Touaregs of the Flatters mission administered a cold douche, and for the time being the subject dropped. It has been revived of late by M. Leroy Beaulieu and other writers. Two lines are projected, one to Lake Tchad, the other to Timbuctoo. The distance to be covered is enormous, in each case about 2700 miles, of which 2000 is desert. The engineering difficulties are not great, but the commercial prospects of such a line seem very poor. A train or two a year would deal with all the existing traffic, and there appears little scope for development. It is suggested that the Upper Niger may become another Nile, but even then its trade would seek an outlet rather to the Atlantic than to the Mediterranean and across the Great Sahara. The post route to South America might be shortened a little, but at what cost and inconvenience! The best hope for the would-be railway builders lies in the discovery of minerals. A mining industry would develop the Sahara as it has developed the bare uplands of the Transvaal and the icy wastes of Klondyke. But of this there is no present indication. Meantime, in the extreme west, on the borders of Morocco, the railway has been extended as far as Colomb-Béchar, a distance of 728 kilometres to the south-west of Oran. This is a strategic line. It is in the direction of Morocco that the eyes of the army of Africa are now turned. French writers are never tired of repeating that Barbary is one, and should be undivided, that the masters of Tunis and Algeria must be lords of Morocco too. The safety of Algeria itself is said to depend on the French control of Morocco. Such is ever the language of him who would go forward. We have said it ourselves often enough, and to fix the limits of empire is sometimes more difficult than to advance them. It may be worth while to note what is the present military force of France in North Africa. According to the project for the Budget of 1911, the force in Algeria consists of 2134 officers and 52,927 men; in Tunisia of 698 officers and 17,007 men. The cavalry numbers in all 440 officers and 9074 men. The number of native troops is singularly small, about 15,000 infantry and 1800 spahis. Judging by our experience in India it would be possible to make a far larger use of native military talent, to the great advantage of the population, and to the consolidation of the French hold on the country. The native troops employed in the late Morocco campaign, especially the Tunisians, bore themselves with the greatest credit.
