" the better ; for by no lefs feverity will this ill-natur'd mould be

Rotten-wood, and faw-duft when rotted, fays Mr. Miller too, 

 is a very good manure for ilrong lands, becaufe it loofens the parts 

 of the earth, and renders it light. 



Mr. Liflc, Vol. I. p. 26. advifes, as a good way, -"to tame 

 " h-arfli, churlilTi, obilinate clay, to fling it up in ridges in the 

 '* v.'inter, and after the firft froft, when it thaws and molders, to 

 " fling and temper amongft it afhes or chalk, or whatfoever you 

 " have to qualify it : for the time being nickt, v/herein you can 

 " catch the clayey corpufcles under the greatefl: difunicn and fcpa- 

 " ration, is the time for keeping them fo, by mixing thefe other 

 " lighter bodies amongft them, vvhich will the longeft prevent 

 " them from their re-union." 



Sea-fand and ihells are ufed to great advantage as a manure, in 

 many places where they can be had without too much expence. 

 JVIr. Miller advifes them chiefly for cold fl:rong land, and loam in- 

 clining to clay. They feparate the parts ; and the falts which are 

 contained in them, are a very great improvem.ent of land. Coral, 

 and fuch kind of ftony plants which grow on the rocks, are filled 

 with falts which are very beneficial to land. But as thefe bodies 

 are hard, the improvement is not the firlt or fecond year after they 

 £re laid on the ground, becaufe they require time to pulverife them 

 before their falts can mix with the earth to impregnate it. The 

 confequence of this is, that their manure is lafcing. Sand, and the 

 fmaller kinds of fea-weeds, will enrich land for fix or feven years j 

 and fliells, corals, and other hard bodies, will continue many years 

 longer. 



In fome countries, at a great diuance from the fea, great quan- 

 tities of fofiil-fliells have been difcovered, and ufed with fuccefs as ' 

 manure : but they are not near fo full of falts, as thofe fliells which 

 are taken from the fea-fliore ; and therefore the latter are always to 

 be preferred. 



Sea-fand is much ufed as manure in Cornv/all, fays Mr. Forlace 

 in his Natural Hiftory of that county. The befl;" is that whi. h is 

 intimately mdxed with coral. In places where this excellent manure 



is
