The tonnage of goods carried amounts to about 16,000,000 tons, or 4 tons per inhabitant, which must be considered fairly large, especially as no great proportion of the tonnage consists of minerals on which there is usually a low freightage.
Minerals remained for the most part unworked, though the profitable coal fields and oil wells in Ferghana were used when disturbances in Trans-Caspia cut Turkestan off from the Baku oil, on which it relies entirely for its industrial life.

The astrological belief that plants, animals and minerals are under the influence of the planets is shown in the older names of some of the metals, e.g.

The platy minerals have also a perfect cleavage parallel to their flat surfaces, while the fibrous species often have two or more cleavages following their long axes; hence a schistose rock may split not only by separation of the mineral plates from one another but also by cleavage of the parallel minerals through their substance.
A large number of minerals may occur as accessories, e.g.
Occasionally serpentines become sheared without yielding talcose minerals; they are then known as serpentine-schist and antigoriteschist, the latter being tough leek-green rocks, more or less transparent.
