following table will give a better idea of the relation existing between 

 some of these feeds and the ordinary feeds of the farm. These analyses 

 are authentic: 



One of the by-product foods mentioned above is likely to become of 

 great interest and importance to practical dairymen. We refer to soluble 

 blood flour. This preparation has been tried and proven to be an excel- 

 lent food to develop rapid growth in young calves feeding on skimmed 

 milk. Different stations have found that blood meal absolutely cures and 

 prevents scours, which causes so much trouble with skim milk fed calves. 



Digester Tankage is a food for hogs only. It is made from pure meat 

 scraps thoroughly dried and carefully ground. Hogs eat it greedily and, 

 as noted before, make large and satisfactory gains. 



Meat Meal is a product of higher grade meat scraps dried and ground, 

 and is meeting with a large demand from poultrymen who wish cheap 

 winter eggs. Every practical poultryman knows that no food is a better 

 egg stimulant than meat scraps fresh from the butcher shop. Such scraps 

 cannot be stored except in refrigerators during hot weather, so are not 

 available to many poultrymen. Many of our best breeders of pure bred 

 swine are thoroughly alive to the fact that if they are going to develop 

 bone in their breeding stock, they must make a radical change in the 

 methods of breeding, feeding and treatment. It has been a practice in 

 Great Britain and Germany for many years to feed swine especially early 

 in life, liberal rations of ground bone. Ground bone contains a large 

 amount of digestible protein from 20 to 25 per cent, and is rich in phos- 

 phates, containing from 50 to 55 per cent. It will be readily seen that 

 this material affords the swine breeder valuable help in overcoming the 

 serious defect in this breed stock. In conclusion we would say that we 

 believe that a great future is in store for the use of animal foods. We 

 believe that it is a matter of only a few years until every available 

 material from our great packing house will be converted into palatable 

 and nutritive foods for the growth and maintenance of farm live stock. 



LEGUMES IN IOWA. 



James Atkinson, Des Moines, Iowa. 

 A study of the principal crops grown in the state of Iowa will reveal 

 the fact that most of them are non-nitrogenous in their nature, that is, 

 they are lacking in those elements and compounds that are required for
