A sort of raft used in the East Indies, Brazils, and elsewhere: those of the island of Ceylon, like those of Madras and other parts of that coast, are formed of three logs; the timber preferred for their construction is the Dúp wood, or Cherne-Maram, the pine varnish-tree. Their length is from 20 to 25 feet, and breadth 2-1/2 to 3-1/2 feet, secured together by means of three spreaders and cross lashings, through small holes; the centre log is much the largest, with a curved surface at the fore-end, which tends and finishes upwards to a point. The side logs are very similar in form, and fitted to the centre log. These floats are navigated with great skill by one or two men, in a kneeling position; they think nothing of passing through the surf which lashes the beach at Madras and at other parts of these coasts, when even the boats of the country could not live upon the waves; they are also propelled out to the shipping at anchor when boats of the best construction and form would be swamped. In the monsoons, when a sail can be got on them, a small out-rigger is placed at the end of two poles, as a balance, with a bamboo mast and yard, and a mat or cotton-cloth sail, all three parts of which are connected; and when the tack and sheet of the sail are let go, it all falls fore and aft alongside, and being light, is easily managed. In carrying a press of sail, they are trimmed by the balance-lever, by going out on the poles so as to keep the log on the surface of the water, and not impede its velocity, which, in a strong wind, is very great.
