Long poles, as a rule numbering four, with white flying prayers, could be seen outside each tent, or one to each point of the compass, the East being taken for a starting-point. Around the interior of the larger tents there was a mud wall from two to three feet high, for the purpose of further protection against wind, rain and snow. These walls were sometimes constructed of dried dung, which, as time went on, was used for fuel. There were two apertures, one at either end of the tent; that facing the wind being always kept closed by means of loops and wooden bolts. [Illustration: BLACK TENT] The Tibetan is a born nomad, and shifts his dwelling with the seasons, or wherever he can find pasture for his yaks and sheep; but, though he has no fixed abode, he knows how to make himself comfortable, and he carries with him all that he requires. Thus, for instance, in the centre of his tent, he begins by making himself a _goling_, or fireplace of mud and stone, some three feet high and four or five long, by one and a half wide, with two, three, or more side ventilators and draught-holes. By this ingenious contrivance he manages to increase the combustion of the dried dung, the most trying fuel from which to get a flame. On the top of this stove a suitable place is made to fit the several _raksangs_, or large brass pots and bowls, in which the brick tea, having been duly pounded in a stone or wooden mortar, is boiled and stirred with a long brass spoon. A portable iron stand is generally to be seen somewhere in the tent, upon which the hot vessels are placed, as they are removed from the fire. Close to these is the _toxzum_ or _dongbo_, a cylindrical wooden churn, with a lid through which a piston passes. This is used for mixing the tea with butter and salt, in the way I have described as also adopted by the Jogpas. [Illustration: A DONGBO OR TEA CHURN]
