of 1901-2.* The feeding trial in this case was with a calf meal prepared 

 according to Hayward's own formula. In England, calf meals are fed 

 by nearly every farmer, and Hay ward took as a basis for his formula 

 the following mixture, recommended by the Agricultural Colleges of 

 England: 



Flour i6 pounds 



Flaxseed-meal 33^- " 



Linseed oil-cake meal 50 



With this formula as a basis, a fairly satisfactory meal of the fol- 

 lowing composition was made Oct. 15, 1901: 



Wheat flour 30 pounds 



Cocoanut-meal 25 " 



Nutrium 20 " 



Linseed-meal 10 



Dried blood 2 " 



It was supposed that the wheat flour would serve to regulate the 

 bowels, besides furnishing considerable nourishment. Only high-grade 

 flour was used, but it was thought that a low-grade of commercial 

 flour might serve as well. 



Cocoanut-meal is a by-product in the manufacture of cocoanut-oil. 

 It was analyzed at the Pennsylvania Station and found to contain 20% 

 protein and 9.03% fat. As cocoanut-oil is of a complex nature, the 

 meal is likely to become rancid in a short time. The meal also has a 

 strong odor of cocoanut-oil. For these reasons it might not be relished. 

 It proved fairly satisfactory, however, in this trial. 



Nutrium is a soluble skimmed milk powder manufactured by the 

 National Nutrient Company at Jersey City, N. J. It is manufactured 

 by drying skimmed milk at a comparatively low temperature and by 

 a certain method of agitation. Nutrium has the appearance of wheat 

 flour and, because it is dry, will keep indefinitely in a dry place. Its 

 composition as determined by the Pennsylvania Station was: 



Water 8.60% 



Ash 6.62% 



Protein 33-93% 



Lactose 50.50% 



Being virtually skimmed milk dissolved in water, it was thought that 

 a great part of the success in the feeding of the calf meal was due to 

 the nutrium used. The chief objection to the nutrium was its cost.
