But; pulverization is absolutely necessary to prepare the soil for the reception of those particles; for earth, in its natural compact state, admits neither rain, dew, snow, nor any of those finer and more subtilized particles which are continually floating in the atmosphere, descend with them to the earth, and are carried off with them in the streams they form on the surface together with such other particles as they take up and arrest in their way' In In this respect nature is particularly assisted by the drill-husbandry, which breaks, divides, and pulverizes the foil, so as to prepare it for the easy entrance os those fertilizing principles with which the atmosphere abounds., Hence it is evident, that the advantages of the drill-husbandry are very great, and that it is far superior to the broad-cast method, whether it is considered as connected with the horsehoe, or only for sowing the land in equidistant rows. But the following comparative experiments will set the advantages of the drill above the broad-cast husbandry in so clear a point of view that he that runs may read. t t In the year 1783, I began those experiments upon various kinds of foil, and in every one of them I employed two acres of land, laid up in eleven feet ridges, and drilled and sown broadcast alternately.'
