A straight, smooth piece of round rod iron, with a screw and nut on oneend, is then inserted for an axle, and two strips of board placed on each sideto receive the ends of the axle. A washer made of sole leather may be placedon each side of the wheel and inside the strips of board. These two stripshave blocks placed between them to ke^p them at suitable distances apart, anda cross bar is passed through the rear end for a THE REEL ROD MEASURE. For measuring farms of moderate size, this will be sufficient, with the ad-dition of a strip of red cloth on one of the spokes, so that each revolution maybe easily counted by the operator as he pushes the machine before him. This machine may be made of pine, which is light and sufficiently stiff, butthe arms or spokes should be of oak or other hard wood. If they are half aninch thick and two inches wide at the hub, tapering to an inch or leas at theouter end, they will be quite stiff enough. Any ingenious farmer who has aworkshop will readily make one. The measurements will, of course, be nearest correct on smooth, hard a freshly plowed field they will be attended with considerable inaccuracy,and should be made after the field is harrowed and settled. On a smooth sur-face there is rarely a variation
