with clay and manure, and another half rood 

 of the fame field with linae and manure, yon 

 will find a great difference in the crop. Clay 

 will enrich a fandy foil j sLs/and in like manner 

 will ameliorate 2i Jliff clay : by being bleaded 

 together, the rigidity of the clay is overcome, 

 and the mafs is rendered fertile. In fome 

 lands where the flrata of earth are thin (as in 

 Nottingham foreft) I have obferved a light bo- 

 dy of fand covering a bed of clay. By plough-, 

 ing fufficiently deep, the two bodies are inti^ 

 mately mixed and connected, and form a mod 

 excellent foil with little labour. 



I do not mean to fay, that lime may not be 

 ufed to advantage where the foil is very fandy, 

 or mixed with gravel. But on a loam or clay, 

 jime is often pernicious in fome degree, as it 

 will bind the foil like a rock, and effeftually 

 prevent vegetation. For plaftering walls, the 

 workmen ufe for the firft and mod folid coat a 

 mixture of lime and loam. A fpoonful of lime 

 made of the gypfum fo common in Derbyfhire 

 and Lincolnfhire will convert half a pint of wa- 

 ter to a folid mafs ; which is ' furely proof 

 enough of the binding quality it is poirefTed of.
