THE PERSIAN WHEEL.
A woman is sticking cakes of cow-dung on the wall to dry for fuel. This article, called oplā, is generally used by the poorer classes; 1280 cakes are sold for a rupee: when well prepared and dried it blazes like wood. On the right is a fine Persian wheel: the water is brought up in gharas, red earthen vessels fastened round its circumference; it is worked by two bullocks, and gives an abundant supply. A wheel of this sort is perhaps superior to any other method of drawing water.
