 use to which land may be put. The supply of 

 any product is governed by the price in relation 

 to the profits offered by competing agricultural 

 industries. The alternatives may be roughly

 (i) Breadstuffs. 



(2) Feeding Stuffs for Cattle.

 a raw material for manufacture and of a cattle

Under certain circumstances the by-product

 system. The availability of transport facilities
