§0f the original pigs on soy beans, one-half at close of bean season were put on 

 bluegrass and the other half in dry lot. 



The superiority of rape over soy beans and cowpeas is manifest not 

 only in the average daily gain of the 1913 test but in the lesser cost 

 of gains and in the larger profits on the acre basis. Under average Iowa 

 conditions counting rent at $3 an acre it costs approximately $12 to 

 $15 to grow an acre of cowpeas or soy beans. 



In the 1912 feeding trial the soy beans cost $13.96 an acre whereas 

 alfalfa cost only $10.75, rape $9.28, and bluegrass $6. The $13.96 cost is 

 distributed thus: $6 for rent on land, $2.80 for preparation including 

 plowing, double discing, harrowing and drilling, 50c for inoculation and 

 $4.66 for seed. This seed was charged at current rates of $3.50 a bushel, 

 which counting additional cost of freight, drayage and so on, is a very 

 reasonable nowaday cost. In 1913 the cost of the soy bean pasture was 

 $12.80 on the acre, the lesser cost than in previous years being due to a 

 little lighter seeding. Dwarf Essex Rape in 1913 cost $9.28, this cost 

 being distributed as follows: $6 for rent, $2.80 for preparation, 48c for 

 seed; but even though the cow peas and soy beans had cost the same 

 as the rape, the profits would have gone "rapeward." 



That there should be an actual loss on the acre in both cow peas 

 and in one of the soy bean fields is somewhat discouraging to the 

 cowpeas-soy bean enthusiast. Certainly $3.76 is a magnificent apparent 

 profit as compared to these other adverse showings. That this $3.76 is
