HOOKAH (the English spelling of the Persian and Hindustani huqqu, an adaptation of the Arabic huqqah, a vase or casket, and by transference a pipe for smoking, probably derived from the Arabic huqq, a hollow place), a pipe with a long flexible tube attached to a large bowl containing water, often scented, and resting upon a tripod or stand. The smoke of the tobacco is made to pass through the water in the bowl, and is thus cooled before reaching the smoker. The narghile of India is in principle the same as that of the hookah; the word is derived from nargil, an Indian name for the coco-nut tree, as when the narghile was first made the water was placed in a coco-nut. This receptacle is now often made of porcelain, glass or metal. In the hubble-bubble the pipe is so contrived that the water in the bowl makes a bubbling noise while the pipe is being smoked. This pipe is common in India, Egypt and the East generally.
