unthrafhed grain be put into the mill in fall quantities, it is almoft impoffible that it can be completely feparated from the ftraw*.

But. though, when the fize of the machine is confiderable, the expence of ereé- 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{mall mill-ftones added to them, for the purpofe of crufhing and grinding grain for horfes,{wine, and other animals; and alfo inftruments for cutting{traw into chaff.

On the neceflity of employing machines of this kind, it is remarked by an able writer, that it is the only method left for having the corn cleanly and properly thrafhed.‘They are fo quick in the work, that the whole may be done under the eye of the mafter, and the corn fecured in the granary without the leaft pilfering. The

faving, by this means of thrafhing, in the extra quantity of corn procured, and the

fecurity again{t having the corn{tolen in the chaff, it is alerted, amounts to an advan- tage in favour of the mills of about ten per cent on the corn crops; in fome cafes, to one fhilling a bufhel on wheat, and very generally to twenty fhillings an acre on the wheat crops fT. 7

This machine has undoubtedly many advantages over the flail, as well as thofe of faving time and hands; asin thrafhing damp corn, not capable of being fully accom- plifhed in any other way, efpecially in wet feafons; and with{mutty wheat, which is thrafhed by it without any mifchief being done to the found grain, the{mut not being crufhed comes out whole, and is blown away with the chaff.

The principal objeGtions 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 ftraw at a time. Thefe objedtions 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 be apprehended from them, or as may be readily obviated. The difficulty in regard to the flraw may be eafily removed, by having it properly ftacked up or cut into chaff.
