now so freely offered in our Massachusetts market made il 

 necessary to conduct feci lino- experiments with milch cows 

 and digestion tests with sheep in order to get at their nutri- 

 tive value. Old and new process linseed meals, cotton- 

 seed and soja-bean meals, Chicago, Pope and King gluten 

 meals, compare quite favorably with each other; all are 

 valuable milk-producing feeds. Not more than two or 

 three quarts of the Pope or King meal should be fed daily, 

 because of the large amounts of fat contained in them. We 

 have fed as high as four quarts of Chicago meal per day 

 without causing trouble. Buffalo and Peoria gluten feed 

 and Chicago maize feed have likewise been tested, and 

 proved about equal in feeding effect. The following table 

 may prove interesting, showing the approximate compar- 

 ative commercial values of the different feeds based on the 

 amounts of digestible protein the;/ contain: — 



Per Ton. 



Corn meal, $21 00 



Wheat brans, 18 00 



Gluten feeds, 23 00 



Gluten meals, 28 00 



Cotton-seed meal, 30 50 



New-process linseed meal, . . . . . . 29 00 



Old-process linseed meal, 28 25 



The above figures do not express the relative physiologi- 

 cal effect of the different grains, but show rather their com- 

 parative values in digestible protein, after figuring the diges- 

 tible carbohydrates and fat in all at a definite price. They 

 can be used as guides in purchasing. 



An investigation into the composition of cream from one 

 hundred and sixty-five different farmers, raised by the deep- 

 setting process, has only emphasized the unreliability of the 

 "space" as a basis of payment. The amount of butter fat 

 in such cream was found to vary from 11 to 22 per cent. 

 The Babcock system, in which the cream is valued by the 

 amount of butter fat it contains, should by all means he 

 substituted. This method is now in general use in the 

 western and northern Stales, and our Massachusetts cream- 

 eries in neglecting to adopt it are most certainly shutting 

 their eyes to progress.
