ket i)iiees ; gluten meal, $22.50, wheat brau, $23.00, and hay, $15.00 

 per ton ; corn meal has cost cliuing our trials $28.00, per ton. It has 

 been the aim in our subsequent statement of results to render promi- 

 nent the controlling influence of the daily yield of milk, on its 

 cost under a corresponding system of feeding.. It will be no- 

 ticed in our trials, that under nearly identical conditions, as far 

 as kind of fodder and period of milking are concerned, the milk of 

 one cow as compared with that of an other one may cost the owner 

 of the animals from 40 to 90 per cent, more in one case than in the 

 other. A careful comparison of the subsequent detailed statement 

 of our late experiment with those of previous Bulletins, (Nos. 10 and 

 11 )\ tends to show that a good gluten meal at the stated cost, ought 

 to be considered a valuable addition to our commercial concentrated 

 fodder articles. The rations fed during the first feeding period and 

 at the close of the experiment, (IV Period), deserve from an econom- 

 ical standpoint a trial on the part of dairymen. Our results were 

 'satisfactory as far as the yield of milk of a good quality is concerned.
