it is naturally apt to clod in wet ; and it fliould be mixed \vith 

 earth or fand to keep it from clogging together, that it may be 

 firewed thin, beint? naturally very hot and ftronr". 



Human dung is another great improver of ail coid lour lands, and 

 efpecially if it be mixed with other earths or dungs to give it a 

 fermentation. 



But there is not any fort of manure equal to the cleanfing of the 

 flreets of great cities, for all ftubborn clayey foils, the parts of 

 which will be better feparated, and in a much lefs time, with 

 this manure, than v»nth any other compoft whatever. 



II. Of Sand. 



T> Y the fame rule that fand fertilifes ftrong clayey grounds, clay 

 -'-' meliorates light and fandy foils. But this manure can never 

 have its due etteft, unlefs it be well broken, and divided into fuch 

 fmall particles as to be able to incorporate thoroughly with the 

 light earth. 



" Arenous and fandy earth," fays Mr. Evelyn, p. 19. wants liga- 

 " ture; and befides, confifting of fliarp and afperous angles, it wounds 

 *' and galls, curls and dwarfs our plants, without extraordinary 

 " help, to render the paffages more llippery and eafy : and there- 

 " fore relenting chalks, or chalk-jnaj-Ie, is profitable, with calcina- 

 " tions of turf, or fea-ivrack, where it is at hand : and if the foil 

 " be exceeding bibulous, fpread a layer or couch of loam, difcreetly 



•' mingled, at the bottom, to entertain the moifture. Sand, 



" being of an open and loofe contexture, is apt to put forth a for- 

 *' ward fpring, as more eafily admitting the folar rays: but it 

 " does not continue, and is an infirmity which maybe remedied 

 " with loam, which not only unites it clofer for the prefent, but is 

 " capable in time to alter and change its very nature alfo, fo as too 

 " hot a conipoji be no ingredient with it. — If the foil be fandy, or 

 " other light mixed earth, imbody it with fomething of a fatter 

 " nature, as 7narl ; and be fure fo to ftir and lay it (efpecially if 

 " with loam) that it may not fink too deep, and fuddenly, as 'tis 

 " apt to do, and fo defert the furface-mould, where it ihould do 

 " the featj and therefore it is to be the oftener renewed." 



Dr. Lifter divides the Englifh fands into tv/o clafi"es : the firft, 

 fharp or red fand, confifting of fmall tranfparent pebbles, naturally 

 found on the mountains, and not calcinable : the fecond, foft or 

 fmooth.
