REAPING-MACHINES. 385 land till 1832, at tbe Highland Society's Show in Kelso, where it was tried before a Committee with a success verv similar to those that had gone before it. Though not affording entire satisfac- tion it nevertheless possessed some points of considerable importance. In construction it was more compact than some of the previous machines ; and, from the simplicity of its movements, â would be less expensive. It was drawn by one horse, walking before the machine, and by the side of the standing corn, cutting a breadth'of from 3^ to 4 feet, and would, therefore, cut nearly 10 acres in 10 hours. The cutter was on the revolving principle, but instead of being circular, it formed a polygon of 12 sides, each side of the polygon being a separate blade, removed and changed The gatherer was the revolving cylindrical drum with rakes, afterward adopted by Mr Smitli of Deanston. before alluded to; but in Mr. Mann's machine the drum revolves at a considerably higher velocity, making 26 revolutions in a minute, while the cutter makes about ^00 In this nfachine, therefore, the velocity of the rake teeth is 400 feet per minute, or nearly double that in Mr. Smith's improved form. This high velocity of the rake carries away the cut grain in a thinner layer upon the rakes, but it requires the application ot a comb to strip the com from the rakes, and thus secures its being always dropped at one point m the machine. The mo- tion of the cutter and rake were obtained from one of the carnage-wheels as m the others; but here they were communicated by pitch-chains, and the front part of the machine was supported by a , to the stem of which the horse-shafts were attached, the castor-wheel runumg by the side of the'standing corn. I am not aware of this machine having ever made farther pro- gress ; though
