Implements of Hufbandry—TLurnip-Drill. 7

quantity of feed on the acre, at any required depth, with intervals of eight, nine, eleven, or eighteen inches, and at two, three, or four feet width, with confiderable exaétnefs; and that wherever it fails of fuccefs, he fuppofes, it muft proceed from the want of proper attention in the perfon who makes ufe of it. With him it has been found ufeful upon all foils, except fuch as are{tony or rocky, and he thinks it may be employed with equal advantage on ftrong clays and clayey loams, as on thofe of the lighter kind.‘This drill is conftru€ted fomewhat on the fame principle of that which has been juft mentioned, and is certainly capable of pretty general application. One invented and employed by Mr. Ducket is alfo fimple in its nature, and likewife faid to be capable of being managed with great eafe, by an ordinary workman.

A machine of this kind, which the Kentifh farmers find very convenient for drilling wheat, barley, oats, peas, tares, and various other crops, is made by Mr. Wellard, of Deal. It is drawn by two horfes a-breaft in a double pair of fhafts, and drills feven rows at a time, feven inches apart. From the peculi- arity of its conftruction, any quantity of grain required per acre can be drilled, and from its great fimplicity it is not liable to be put out of order. It cofts about four- teen guineas.|

Turnip-Drill.—An ufeful inftrument of this fort has been contrived by Mr. Bailey, for fowing turnips on the tops of one-bout ridges. In this implement the defects of {owing too much or too little feed are obviated. It confifts of a folid cylinder, made of iron or brafs, about two inches in diameter and one inch broad, on the furface of which are formed fifteen or fixteen cavities refembling the form of a femi-egg when cut longitudinally, and as deep as to hold four or five feeds each. On the back of the cylinder, a little from the top, is placed the hind part of the hopper, to which is fixed a piece of iron or brafs one inch long and half an inch broad, hollowed on the infide into the form of a Gothic arch, the fides of which mecting the fides of the cavities in an oblique angle, prevent the feeds from being bruifed: at the lower end of this piece of iron, or gatherer, there is a flit three-tenths of an inch long and one-tenth wide; and at the back of-it, a thin flat piece of iron moves up and down by means of a{crew at the top of the hopper, which enlarges or leffens the orifice direétly above the cavities, and increafes or diminifhes the quantity of {eed delivered, as the operator may think proper.‘This flip of iron, or regulator, is let into a groove made in the board which forms the back part of the hopper.

The cylinder is fixed before the cavities are made, on an iron axle one inch {quare, turned very true, as well as thofe parts of the axle which turn in the col- lars fixed in the handles.‘To the ends of the axle, two wheels, twenty-fix inches in diameter, are fixed, which turn the axle and cylinder round, and which in
