Howards system consists in a stationary enginedriving a windlass, having two winding drums, withdirect and reverse action, placed in front of it, roundwhich is coiled about IGOO yards of wire-rope. Bya simple lever movement, the man can droj) thewinding drums out of gear in an instant, a conti-iv-ance which enables him to attend to the i)roper.

The engine is usually placed at the corner of the plot to be ploughed, the rope is carried round the field on rope-porters, and fixed at the corners by light anchors. A snatch-block placed in front of the windlass prevents the slack- theground. The plan of working given clearly illus-trates the arrangement (fig. 13). The plough, as willbe seen from fig. 14, is composed of two strong ironframes balanced upon four wheels, and crossing eachother at their inner ends, thereby decreasing thelength of the plough, and, as a matter of course, the
