" all sour, surly lands." — Chemistry rationally explains, the 

 time and mode of applying it. — He next dwells upon t!ic plough- 

 ing' in green Crops for manure, the best of which he says are 

 Buck Wheat and Tares, in which our present Agriculturists 

 agree. 



Sect. 5. Is dedicated to manures, and first of horse or stable 

 manure, which he considers as best for cold, clayey soils, as 

 that of horned Cattle is for hot ground— he recommends small 

 quantities to be applied at a time and often repeated, in 

 compost rather than simply varying them with the soil. 



Section. 6. On Sheep and Hog's dung, and Night soil, is 

 short and superficial, though he strongly recommends them, 

 yet he does not seem to dwell enough on what arc certainly the

 than the error that they ought to be left exposed to the air 

 some time before being used, which he recommends. 



Sect. 8. Is chiefly devoted to Marie, the discrimination of 

 the varieties of which are as vague as usual, where chemical 

 characters are unknown or unnoticed. He classes them ac- 

 cording to their colour ; his practical observations are good, 

 except in the proportions he mentions as being applied, varying 

 from GO to 400 loads per Acre, the smaller number being in 

 most cases too large. 



Chap. 3. Sect 1. is on " the superficial dressings of land, 

 after they are sown" which he mentions as a practice, " with- 

 in these few years discovered." Among these he reckons 

 folding sheep upon wheat during the winter months. Sect. 2. 

 Is on the dressingMand with coal ashes, — 3. with wood ashes, 

 — 4. with kiln ashes. — 5. with saw dust. — G. with turf ashes, 

 7. with lime,— 8. with malt dust, — 0. with sea sand, in the
