It is hardly necessary to observe, that all sowers in Scot-land use a sheet suspended from the neck for carrying theseed; whereas, in some parts of England, a basket is employ-ed for this purpose. Undoubtedly the sheet is more com-modious and less cumbersome.

OF DRILLING.
As this subject will require to be resumed, when consideringthe several crops to which the drill husbandry is peculiarlyapplicable, it needs only to be treated of in a very generaland summary manner in the present section. Drilling maybe considered under two distinct views: I. As applicableto what are usually called leguminous crops, for which it isadmirably calculated, and therefore generally used for thesein the best'cultivated districts of Scotland ; and, 2. As cal-culated for culmiferous crops, or what are commonly calledwhite corn, as contradistinguished from pulse, which are na-med black victual in the language of Scotch husbandry.
The introduction of the drill husbandry into England hasbeen justly ascribed to the ingenious Jethro Tull; who en-deavoured to substitute a perpetual succession of drilled crops,in place of fallow and manure; the former of which he cen-sured as a temporary and unnecessary abandonment of pro-ductive land, and the latter as a needless and heavy expence.
