5. An account of any manure expended.

As the object of the Society is to ascertain, as far as possible, the advan- 

 tages of subsoil ploughing (in which the subsoil is divided by the 

 plough, but left in its original situation), and of trench ploughing 

 (in which the subsoil is not only divided, but is also brought to the 

 surface), they strongly recommend to competitors that the two 

 processes should be conducted on a piece of ground fairly divided 

 into two lots of equal quality, and that the drains cut in each lot, 

 as well as any assistance afforded by manure, should be similar on 

 each of the lots.

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

 advantages of the single-horse carts which are generally used in Scot-

 tised in any part of England, or in any foreign country; having regard 

 to economy of labour both of men and animals, quickness of work, and 

 facility in loading and conducting ttie carriage. 



11. Agricultural Mechanics. 



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