Of all the modern implements introduced, this may bepronounced the most valuable and most generally appreciated,and the most useful for effecting a variety of differentmechanical operations, and in giving a fine tilth to thesoil. Fig. Crosskills roller, as now manufactured, is the result ofgreat experience in its use, a variety of improvements havingbeen made in it since it was first patented. It has alwaysbeen brought to compete with rollers of similar character,and always carried away the prize—no other implement ofits kind ever having stood the least chance when in compe-tition with it. crosskills 69 This implement is successfully applied to effect the threedifferent purposes for which the spike-roller, the Norwegian,and the wheel-roller are employed, and effects the objectbetter than these three combined. The advantages gainedby the use of this implement are—first, the lessening theexpenses of tillage by mechanical aid, in crushing the hardestclods, and pulverising the roughest fallow land; secondly,in compressing light and puffy soil to grow therefromstronger and more productive plants; thirdly, in rollingcultivated land, and preventing th
