unthralhed grain be put into the mill in fmall quantities, it is almod impollible that itcan be completely feparated from the draw*.

But though, when the ftze of the machine is confiderable, the expence of erett-ing it may be from eighty to one hundred pounds, according to fituation and mate-rials, fmaller ones may be erected at much lefs, as from thirty to fifty pounds.

Some of thefe kind of mills have rollers or fmall mill-dones added to them, for thepurpofe of crufhing and grinding grain for horfes, fwine, and other animals ; and alfoindruments for cutting draw into chaff.

On the neceflity of employing machines of this kind, it is remarked by an ablewriter, that it is .the only method left for having the corn cleanly and properlythrafhed. '1 hey are fo quick in the work, that the whole may be done under the eyeof the mader, and the corn fecured in the granary without the lead pilfering. Thefaving, by this means of thrafhing, in the extra quantity of corn procured, and thefecurity againd having the corn dolen in the chaff, it is afferted, amounts to an advan-tage in favour of the mills of about ten per cent on the corn crops; in fome cafes,to one (hilling a bufhel on wheat, and very generally to twenty (hillings an acreon the wheat crops f.

This machine has undoubtedly many advantages over the flail, as well as thofe offaving time and hands •, as in thrafhing damp com, not capable of being fully accom-plifhed in any other way, especially in wet feafons; and with fmutty wheat, which isthrafhed by it without any mifchief being done to the found grain, the fmut not beingcru(hed comes out whole, and is blown away with the chaff.

The principal objections that have been made to thefe machines, are the great ex-pence of ereCting and ufing them, their tendency to diminifh the labour of the poor,and their affording too great a fupply of draw at a time. Thefe objections are, how-ever, of little confequence, when the general utility and advantages of fuch ma-chines are confidered; befides the latter are either fuch as have nothing to beapprehended from them, or as may be readily obviated. The difficulty in regardto the draw may be eafily removed, by having it properly dacked up or cut intochaff.
