TRIAL OF A NEW SAW.

On Saturday afternoon Mr Hurrey invited a number of gentlemen to be present at the trial of a saw of a new design, the invention of Mr N. Gibbons. A log of white pine 3ft. Gin. in diameter had been brought in for the purpose of the experiment. A sawyer who was present stated that he and his brother could with an ordinary saw cut through a 3ft. log in 1G minutes, and he is said to have been surprised at finding that a man and a boy could with the new saw get through the log tried on in nine minutes with ease. Several trials were made in competition with ordinary saws, and in each case the advantage was largely in favor of the new saw, both as to time and expenditure of power. The saw is on quite a new principle, arid is said to require no setting. The teeth are in sets of three, of which one is thin with an edge like that of a chisel, the next is the same only with its edge on the opposite side, while each third tooth is the full width of the saw. The side teeth make straight cuts into the wood, and the third tooth cuts horizontally what the side teeth have already cut vertically. There is therefore no sawdust, but the cut wood comes out in little flakes Besides the peculiar canr struction of the teeth, from ed,ge to back for about eight inches in the centre the metal is tapered down from a quarter of

an inch at the edge to something like onesixteenth at the back, which effectually stops any jambing in the cut. It has also an angle of declination much greater than that of the usual saw, thus enab ing bushmen to cut right through a log when the lower side is close down on the surface of the ground, or, as may often happen, a few inches below it. Vertical mill saws on the same principle are now being tested in one of the Auckl-.ind saw-mills. Mr Pric^, of Patutahi, who has had many years experience in felling and crosscutting timber, is sa d to be quite satisfied that the new style of saw will beat any other. Messrs Hurrey and Gibbons intend to apply for patents for two other kinds of saws. •
