pound of dry matter in the form of Atlas meal in place of an equal 

 amount of dry matter in the corn and bran mixture, increased the 

 yield of milk and total solids an eighth, and that of the butter fat a 

 sixth. It was regarded as the cheapest source of protein on the 

 market at that time. 



It has been stated that feeds of this character are likely to pro- 

 duce milk that will sour quickly, and some milk-condensing factories 

 prohibit their use. Whether such statements are the results of care- 

 ful investigation is uncertain. It would hardly be wise to feed these 

 grains should the milk be intended especially for infant feeding, but 

 for ordinary purposes it is believed they are not objectionable and 

 are worthy of the attention of dairymen interested in economical 

 sources of protein.* They should always be bought o?i a guaranty. 



There are at present some forty-two breweries in 

 Brewers' Massachusetts. The residue is practically all sold 

 Grains. • undried to farmers living in the immediate vicinity 

 at prices varying from seven to ten cents a bushel. 

 Assuming that ;^t, bushels of wet grains weigh a ton, the ton price 

 would be about three dollars at the brewery, to which the cost of 

 cartage should be added. Four tons of wet grains contain about 

 the same quantity of nutritive material as one ton of dry grains, or 

 1 . 1 tons of wheat bran, or 0.8 tons of gluten feed. With this data 

 at hand, the purchaser of wet grains can calculate at what price he 

 can secure an equal amount of nutrition in the form of dry feed 

 stuffs. The succulency of the wet grains is a factor not to be over- 

 looked in estimating the value of the feed. It is not believed that 

 the wet grain is an objectionable feed-stufif, when fed in a reasonably 

 fresh condition and in moderate quantities. 



Brewers^ dried grains are fed quite extensively in many states. 

 They have been substituted with success for oats as a horse feed, 

 and furnish a cheap source of protein for dairymen. 



Owing to the present high price of oats, it has been

 Horses. horses. The Arabs feed their horses almost exclu- 

 sively on barley. This grain is also fed to horses 

 by the Berbers in North Africa with excellent results. Pott, a Ger- 

 man authority on feed-stuffs, considers barley the best grain for 

 horses, oats only excepted. In view of the extended use of this 

 cereal as a horse feed in other countries, it is believed that it could be
