Here the additional 10 per cent proved a detriment, as shown by a decrease i:\ 

 production and incidentally a decrease in weight as shown in the table of weights. 

 This was, in all likelihood, due to the noticeably relaxed condition of the cows caused 

 by the laxative nature of the molasses substitute, and to the fact that they were, at 

 the same time, receiving a liberal allowance of succulent food in the form of roots. 



As in the case of Experiment 1A, a duplicate test of Experiment 2A was made with 

 the ea.t.i < ti.c mam barn, data being compiled from the production of the same ten 

 cows as in Experiment IB.
