one day than one man in two days. It is, 

 nevertheless, a mistake to have too many men 

 working at the same spot, for they are apt to 

 get in one another's way. If possible, try to 

 arrange your workmen so that one has to keep 

 steadily working in order to keep another 

 supplied with work ; for example, with two 

 men and two barrows, one should be dig- 

 ging and filling while the other is wheeling ; 

 the first should have the barrow filled by the 

 time the second one has returned from deposit- 

 ing his load. If the distance is considerable a 

 third man and a barrow may be worked into 

 the cycle of operations. So also with carting : 

 arrange your men and carts so that an empty 

 cart is never kept waiting at the scene of 

 operations while another one is being filled ; 

 but time it so that the empty cart arrives at 

 the spot as the full one leaves. It is wonder- 

 ful, the amount of time, and consequently 

 money, that can be saved by a little arrange- 

 ment of this sort. 



It is difficult to make anything of an 

 accurate estimate of the cost of clearing land 

 from scrub, so much depends on its nature
