Vessels made in this rude manner are absolutely necessary in the countries wherein they are used. Wooden or metal vessels would be too heavy, and, besides, the slight though constant evaporation that always takes place through the pores of the leather keeps down the temperature of the water, even under a burning sun, the slight loss which is caused by the porousness of the skin being more than counterbalanced by the coolness of the water. It is true that the goat-skin communicates to the liquid a flavour far from pleasant, but in those countries the quality of the water is of little consequence, provided that it is plentiful in quantity, and tolerably cool. In all parts of the world where the skin is used for this purpose the mode of manufacture is practically identical. An account of the art of preparing the goat-skin as practised in Abyssinia is given by Mr. C. Johnston, in his "Travels in Southern Abyssinia:"-- "To be of any value it must be taken off uncut, except around the neck, and in those situations necessary to enable the butchers to draw the legs out of the skin; also, of course, where the first incision is made to commence the process, and which is a circular cut carried around both haunches, not many inches from and having the tail for a centre. The hide is then stripped over the thighs, and two smaller incisions being made round the middle joint of the hind-legs enable them to be drawn out. "A stick is now placed to extend these extremities, and by this, for the convenience of the operators, the whole carcase is suspended from the branch of a tree, and, by some easy pulls around the body, the skin is gradually withdrawn over the fore-legs, which are incised around the knees, to admit of their being taken out; after which, the head being removed, the whole business concludes by the skin being pulled inside out over the decollated neck. One of the parties now takes a rough stone and well rubs the inside surface, to divest it of a few fibres of the subcutaneous muscle which are inserted into the skin, and after this operation it is laid aside until the next day; the more interesting business of attending to the meat calling for immediate attention.
