of the mixture were removed. The production during Period 2 was 

 considerably less than that of the average of Periods 1 and 3 ; never- 

 theless, with one-third of the meal ration valued at the rate of $4.00 

 per ton, and with the lessened amount of meal consumed, the cost 

 of production in the case of the black seeds ration is relatively low. 

 As will be mentioned more in detail, the complete elimination of 

 one-third of the ration might have resulted in still lower cost of 

 production for this short space of time. Nevertheless, on the actual 

 data given, the f oUowing figures may be deduced : 366 pounds black 

 seeds, 60 pounds hay, 126 pounds roots, and 224 pounds of ensilage 

 would be equivalent to 267 pounds meal mixture, for milk pro- 

 duction.
