 man (in this as well other Improvements) to 

 try a little of it on Lands that are fuppofed 

 of a Nature contrary to it, fince a Imall Ex- 

 periment is eafily made 5 but if the Ground 

 be a very ftifFClay, and apt to bind it dovvn^ 

 the Farmer ought to mix it with Coal Allies* 

 or Sea Sand^ which will both together makd 

 an excellent Compoft, and one will free the 

 other from that Ligature and Imprifcnment 

 that Clays naturally lay upon Dung, and 

 every thing elfe that is near its own Nature^ 

 as Marie is. Concerning Lands that are 

 marl'd, 'tis neceffary to obferve, they gene-» 

 rally fpeaking, fow them the fir ft Year with 

 Wheat, the lecond with Barley, and the laft 

 Oats, and fo they repeat it '^ but others are 

 of Opinion, that all Lands are better the fe- 

 cond and third Year after marling, than they 

 are the fiift, and therefore fome begin with 

 Oats, if it be a light Land, and the next Year 

 with Wheat, the next with Peafe, then Bar-^

 five or fix Years, or, if good Land, kv^n or 

 eight, it will be proper to lay it up for Grafs 

 two or three more ^ for by this the Ground 

 affumes new Vigour, and the Marie will not 

 be all gone in fifteen or twenty, and in fome 

 Places twentyfive or thirthy Years* And 

 hereitmuft be noted, that all Lands fnould

 that it is clay'd upon, for otheiwife it may be
