tHe rows of the drills: it will penetrate any depth required. The one with three fhares will, with a pair of horfes, do as much work in one day as three ploughs.” It is however obferved, that this machine will work only upon light land where the fallow is well broken and nearly clean of twitch. Where kitlocks grow it will alfo, he thinks, be found very ufeful; and it is of fuch a fimple conftruction that any

perfon may make it*. SCARIFIERS ano SCUFFLERS.

Turse are inftruments which are in a great meafure fimilar to that juft defcribed,, and which feem daily to be coming into more general ufe for the purpofe of clear- ing and rendering arable land fuitable for the reception of the feed, as well as for fcarifying and ftirring the earth between the rows of drilled crops. They are likewife fometimes made ufe of for clearing ftubble after the crop has been taken off, but for which they are not probably good tools. They are made of various. forms and conftructions, and have commonly a great number of iron plates or feet, the edges of which are well{teeled and kept harp.‘Thefe are moftly fixed to the ends of an equal number of iron bars forming a kind of legs. Some of thefe tools are alfo made with wheels, and others without them; the latter fort anfwer equally well for many ufes, and are much lefs expenfive.. A pair of handles are generally fixed on behind, by which the implements are worked, and, by the difference in the— degrees of preflure, are regulated in refpect to depth at the pleafure of the perfon who has the management of them.‘he feet fhould have a fort of triangular fhape, each of the fides of which may be about fix inches in length. They fhould be fo contrived as to cut up the roots of weeds at a good depth, and not be eafily thrown out of the ground by fuch obftructions as they may occafionally meet with. They may be ufed with different numbers of tines or teeth, according to the dif- ference of intention with which they are employed, and in proportion as the land is clean or foul, loofe or tenacious. The implements of this kind which are made by Mr. Cook are very good ones; and others, contrived with great fimplicity, are defcribed in many of the reports publifhed by the Board of Agriculture.

The main object of thefe inftruments is, that of leflening the ufe of the plough; and in certain fituations and foils they may, without doubt, be employed with more advantage to pulverize the earth and clear the lands from weeds. Lands which have been once ploughed over, in preparation for barley or turnips, may be
