excellent machine, however, was not generally adopted inthis country, till within the last fifty years. The originalconstruction was extremely simple, consisting only of a wheel,with four vans of thin boards, or sheet iron, made to re-volve with considerable velocity within a drum, or hollowcylinder, so as to occasion a strong wind, which issued outat an opening in one side of the drum, the grain being e.<-posed to it, by falling’ gradually through a narrow aperture.This artificial wind blows the chaff and light grain backwards;at the same time the good grain falls, by its superior weight,directly down through the streams of air. Fanners have beengreatly improved since their first introduction, and are now tobe seen, hot only in every corn-irtill, but almost in every barn,where the farm is more adapted for tillage than pasture.Since threshing-machines were introduced, fanners almostin every case are annexed to them; and in many instances,where they are fitted internally with suitable riddles or harps,it is perfectly practicable to measure and market the grain,as it comes from the machine.

It is not a great many years since almost every article inScotland was carried either on horseback, or in very awkwardmachines.
