Natural Liquid Manure. 



1. The nature of those naturally combined ; as the urine of cattle and 



of man, the drainings of stables and farm-yards, &c. 



2. Their mode of treatment and preservation. 



3. Their application both to pasture and arable land ; the soils and 



crops to which they are best adapted; their chemical properties; 

 and the probable causes of their success or failure ; together with 

 observations on the quantity to be employed on clays and lurnip- 

 lands. 



7. Management of Farm-yard Manure. 



Fifteen Sovereigns, or a Piece of Plate of that value, will be given 

 for the best Account of the Mode of Management and Application of

8. On Artificial Manures, or Hand-Tillages. 



Fifteen Sovereigns, or a Piece of Plate of that value, will be given 

 for the best Account of Artificial Mineral and Vegetable Manures, and 

 of the simplest and most effective mode by which their adulteration with 

 spurious substances may be at once detected. 



The following information will be required in the case of each of these 

 classes of artificial manure : — 



Mineral Manures. 



1. The different inorganic or mineral substances which have been 



recommended and used as portable manures: distinguishing the 

 simple from the compound. 



2. The quantities applied per acre ; mode and time of application, 



whether to grass or arable land ; and nature of the soil. 



3. The probable causes of their success or failure. 



Vegetable or Animal Manures. 



1. The different organic and composite manures, whether artificiallv 



or naturally combined ; and their chemical constitution. 



2. The quantity used per acre ; the time and mode of their application, 



and whether to pasture or arable land. 



3. The soils to which the several kinds are best adapted, and the 



probable causes of the more certain and constant effect produced by 

 them than of the inorganic kinds : as also, the causes to which 

 their occasional failure mav be attributed.
