John Thomson: AT certain seasons of the year, camels may be encountered in tens of thousands crossing the desert of Gobi, laden with brick tea, on their way to the Russian frontier. This brick tea, in the absence of metallic currency, forms the circulating medium in Mongolia, Siberia, and Thibet. When in the province of Peichihli I witnessed the departure of a train of 2,000 of these camels laden with brick tea to be sold in the Russian markets. These beasts are also employed in transporting coal, and other commodities, from one part of the province to another, and they are highly esteemed by the Mongols, as they can be easily managed, and can accomplish long journeys in arid regions with scant supplies of food and water. As many of my readers are aware, the camel is physically adapted for traversing the sandy plains of Asia, where they are found in the greatest numbers. The stomach is supplied with bladders which enable the animal to carry a store of fresh water, and in like manner the humps are furnished with a store of food in the shape of fatty matter which may be absorbed in case of need.
