excess of water is removed from the coagulated mass by means 

 of heavy pressure, and it is then passed through steam driers 

 and eventually ground and bagged. As thus treated it appears 

 as ar friable powder of dark color and with only a slight odor. 



For horses that are hard worked y^ to 1 pound daily of 

 dried blood, mixed with the corn, bran and oat ration, will 

 prove very satisfactory. 



For calves, as a remedy against scours, the Kansas experi- 

 ment station recommends a teaspoonful of especially prepared 

 blood (soluble blood flour) added to each feeding of milk. 



'For dairy stock the Massachusetts station has found dried 

 blood quite a satisfactory protein concentrate as compared with 

 cotton-seed meal. 



The conclusions in this experiment were as follows: — 



1. Dried blood contained about 85 per cent, protein, and 

 for cows in milk may be fed in amounts varying from 1 to 2 

 pounds daily, mixed vrith concentrates of vegetable origin. A 

 satisfactory combination for a day's ration for cows producing 

 10 quarts of milk may consist of 2 to 3 pounds wheat bran, 2 

 to 3 pounds corn or hominy meal and 1.5 pounds dried blood. 

 Other mixtures can be made containing blood as a substitute. 



2. It is believed to be the part of economy to first utilize as 

 much as possible of the cattle blood product of the country as 

 an animal food, rather than to apply it directly as a fertilizer. 



3. The present price of prepared blood, its lack of distribu- 

 tion in local markets and the ignorance of the consumer con-, 

 cerning its merits as a food have thus far prevented its general 

 use for feeding purposes. 



]\Ioi-assp:s for Farm Stock. 



In 1007 this station published Bulletin Xo. 118, bearing the 

 above title. Inasmuch as the edition is entirely exhausted, and 

 constant inquiries continue to be received concerning the use 

 of molasses as a food for farm animals, a very brief resume of 

 the bulletin may not be out of place. 



Composition of Molasses. 

 The molasses offered for cattle feeding in New England is 

 the residue resulting from the extraction of sugar from the juice 

 of the sugar cane, and is imported from Porto Pico. It is
