Some millions of Chinese live entirely on the water, in boats and barges of various kinds, some occupied in carrying articles of provisions and merchandize, others in conveying passengers, some in feeding and rearing ducks, and others in fishing. Some of these vessels have masts and sails, others are forced forwards with large sculls or pushed on with poles, some are dragged along by men, and others, but very rarely, by horses. Near the head of each vessel is suspended in some convenient place, one of those noisy instruments well known in this country by the name of gong, which is used to regulate the motions of the trackers, and to give notice to other vessels of the approach and intentions of the one that beats the signal.
