The best time, however, ior strewing this dry manure, is previous to gentle showers, by the aid of which its efficacy will be considerably in- creased. Mr. Kikwav affirms, in his ex- cellent *< Treatise on Manures,* 1 that the gypsum successfully employed in agriculture is of a fibrous tex- ture ; and in Ids opinion clay-soils are. more improved by it than the calcareous. This assertion appears to contradict the experience of those who have employed that sub- stance on a large scale, and espe- cially the American farmers. — We chad not attempt to reconcile these differences, because the same ma- nure may be attended with oppo- site effects on soils variously mix- ed and Combined, The proper H A D [421 gpason for scattering the plast Paris is according to Mr. Kn<- wan, in the month cf Febi uary or March, when it should be strewed on grass-land, at the rate of ei lit bushels per acre ; as a larj 1 1 pro- portion would be detrimental to the soil. He farther observes, that the theory of the effects of gypsum is to be deduced from its uncommon .cptic property ; be- cause it accelerates putrefaction in a higher degree than any other substance. Hence it ought not to be ploughed in, but merely depo- sited on the surface of the land, in order that the old grass may be speedily converted into coal, to nourish the young vegetables. Dr. Darwin, however, ques- tions these deductions concerning bodies promoting putrefaction ; aa the advancement of that process has, in general, been judged of simply by the exhaling odour ; which is liable to be altered, or destroyed, by its union with many bodies, without otherwise affecting the tendency to dissolution.
