proportion, and eventually a large proportion, of the cattle matured in 

 the corn belt must be reared there. Page 15 



Improved and intensified fanning methods, the introduction of corn 

 silage, alfalfa and other forage crops, the more complete utilization of 

 waste roughage, and increased attention to manure as a means of main- 

 taining fertility will tend to render cattle production more practicable. 

 Nevertheless, those upon whom the cattle feeder is dependent for his 

 market must consider the increasing cost of producing cattle and pay 

 prices commensurate therewith; the resumption and extension of beef 

 production will come only as a result of higher relative prices for fat 

 cattle. Page 17

 nomic factors in cattle feeding. The circulars that have been published 

 are: No. 103, Relation of the United States to the World's Beef Supply; 

 No. 10-i. Argentina as a Factor in International Beef Trade; No. 109, A 

 Ileview of Beef Production in the United States. The next circular in 

 the series \\ill treat of cattle feeding in its relation to farm management 

 and soil fertilitv.
