 the interests of tennis and croquet, that is the 

 first operation, and with it should be com- 

 bined draining, if the nature of the ground 

 demands it. 



In the levelling process the top-spit contain- 

 ing the most valuable part of the soil must 

 be first laid aside, to be subsequently distrib- 

 uted over the levelled surface. This done, 

 and the levelling completed, the undisturbed 

 subsoil at that part of the ground which has 

 been lowered must be forked over to a depth 

 of eight inches. The whole surface may then 

 be treated with decayed farmyard manure 

 well forked in, and the top-spit redistributed 

 upon it to form a layer eight inches thick. 



If the original layer of soil is insufficient, 

 now is the time to supplement it by an 

 additional supply imported from outside, or 

 obtained as a by-product from some other 

 part of the garden. Planks should be used 

 where the barrow is in operation; otherwise 

 ruts will be caused that are not easy to 

 obliterate. 



Screening may be practised if the surface 

 layer is stony. It is essential when sowing
