 North Atlantic, and this would render possible some increase in 

 the intensive methods of animal husbandry as practised in those 

 countries. 



NOTE TO CHAP. V. 



The surplus production of rice and other starchy foods in tropical low! 

 also has some bearing upon the subject-matter of this chapter. The agri- 

 cultural resources of the temperate regions are obviously supplemented by 

 any importations into them of milled or unmiiled rice or of rice offals from the 

 tropics. The milled grain reduces correspondingly the quantities of cereals 

 or of potatoes that require to be grown for human food in the former, and the 

 same applies to such materials as sago and tapioca ; while rice offals form a 

 substitute for concentrated feedstuffs of temperate origin. For a discussion 

 of the production of food crops in relation to animal industries, see Chap. xi. 

 below, where also reference is made to the production of sugar in the tropical 

 regions.
