6 Implements of Hufbandry.—Wheel-Ploughs.

| plough, which, from its not requiring great ftrength to draw it, may frequently be i ufed with advantage on fome of the lighter forts of foil, which are pretty free | from{tones and other obftru€ting matters of that nature. But where the land is of | a ftrong, heavy, cohefive quality, and where the roots of vegetables, or other fub- i ftances, afford confiderable refiftance and obftruction, a much ftronger plough muft be employed. Here the Suffolk tron fwing-plough will, probably, be found a much better, as well as a very neceflary and ufeful inftrument, efpecially

| :| when managed by a judicious ploughman. The advantage of this inftrument has ny Wii! been particularly fhewn in breaking up fome of the{trong heavy lands of the | King’s farms in the great park near Windfor. It not only does its work well, but . with greater facility than many other kinds of ploughs which are frequently em- ployed on thefe kinds of foil. The part to which the team is attached in this fort of plough is an excellent contrivance for the purpofe which it is to ferve*. Wheel-Ploughs.—Vhe manner of conftructing thefe ploughs, like thofe of the {wing kind, varies confiderably in different places, according to the nature of foils and other circumftances; but in every form, and in all fituations, they probably require lefs fkill in the ploughman. Wheels feem, indeed, to have Hh formed an addition to ploughs, in confequence of the want of experience in this clafs of men; and in all forts of foil, but more particularly in thofe which are | of a ftony and ftubborn quality, they afford great affiftance to fuch ploughmen, || enabling them to perform their work with greater regularity in refpect to depth, and | with much more neatnefs in regard to equality of furface. From the friction caufed | by the wheels they, however, give much greater refiftance, and confequently demand more ftrength in the team that is employed; and, befides, are more expenfive in their conftru€tion, and more liable to be put out of order, as well as more apt to | be difturbed in their progrefs by clods, ftones, and other inequalities that may be | on the furface of the ground, than thofe of the fwing kind. It is alfo obferved by a late ingenious writer, who feems to have paid much ae attention to the invention and improvement of implements for the purpofes of | hufbandry,“ that with wee/-ploughs workmen are apt to fet the points of their fhares too low, fo as by their inclined direétion to occafion a heavy preflure on the wheel, which muit proceed horizontally;” the effet of this{trugele, he conceives, to be an increafed weight of draught, infinitely beyond what could be fuppofed: for which reafon, he thinks the wheel is to be confidered as of no importance iz fetting a plough for work; but pafling lightly over the furface, it willbe of material aid in breaking old leys, or ground where flints, rocks, or roots of trees occur,
