Pipe-lines, refineries and railroads have been provided and the three big companies operating the whole field consolidated in 1893. The Rothschilds combined with the Nobels and a prohibitory tariff prevents the importation of foreign oils. Tank-steamers ply the Caspian Sea and the Volga, many of the railways use the crude-oil for fuel and the supply is practically unlimited. The petroleum-products are carried in these steamers to a point at the mouth of the Volga River called Davit Foot, about four-hundred miles north of Baku and ninety miles from Astrakhan, and transferred into barges. These are towed by small tug-boats to the various distributing points on the Volga, where tanks have been constructed for railway-shipments. The chief distributing point upon the Volga is Tsaritzin, but there is also tankage at Saratof, Kazan, and Nijni-Novgorod. From these points it is distributed all over Russia in tank-cars. Some is exported to Germany and to Austria. Russian refined may not be as good an illuminant as the American, but it is made to burn well enough for all purposes and emits no disagreeable odor. After taking from crude thirty per-cent. illuminating distillate, about fifteen per-cent. is taken from the residuum. It is called “solar oil” and the lubricating-oil distillate is next taken off. From this distillate a very good lubricant is obtained, affected neither by intense heat nor cold. The lubricating oil is made in Baku, but great quantities of the distillate are shipped to England, France, Belgium and Germany and there purified. Russian competition was for years the chief danger that confronted American producers. Three partial cargoes of petroleum were sent to the United States as an experiment, netting a snug profit. Heaven favors the hustler from Hustlerville, who hoes his own row and doesn’t squat on a stump expecting the cow will walk up to be milked, and American oilmen are not easily downed. They have perfected such improvements in handling, transporting, refining and marketing their product that the major portion of Europe and Asia, outside of the czar’s dominions, is their customer. Nailing their colors to the mast and keeping their powder dry, the oil-interests of this glorious climate don’t propose to quit barking until the last dog is dead! The early Persians and Tartars burned crude-oil for light in stoneware jugs, with a spout on one side to hold the flax-wick, that answered the purpose of lamps. In 1851 a chemist of Polish Austria exhibited a small quantity of distilled petroleum at the World’s Fair in London. The Austrian Emperor rewarded this step towards refining crude-oil by making the chemist a prince.
