EXPERIMENT STATION RECORD. 



"Notwithstanding tlie favorable results in tliis trial, the writer does not feel as 

 yet like recommending the mixture to the Vermont dairyman. We have not thus 

 far been able to grow horse beans successfully. "We have grown them for 2 years, 

 hut neither time have had a satisfactory stand, although the soil conditions seemed 

 favorable." 



Robertson mixture and corn silage vs. roots, J. L. Hills ( Vermont 

 Sta. Ex)t. 1894, pp. 148-150).— At the conclusion of the above experi- 

 ment the cows were fed a mixture of silage made from corn and from 

 Robertson mixture, with hay and grain, for 2 weeks. They were then 

 gradually changed to a mixture of cut beets and carrots in an interval 

 of 1 week, and fed 45 lbs. of this mixture per day for 2 weeks, with the 

 same amounts of hay and grain as in the first period. Analyses of 

 the 2 kinds of silage and of the corn and beets are given, and the data 

 for the feeding trial, including the com])ositiou of the milk, are tabulated 

 for each of the cows. 



"On the wliole, the results appear to be about even. We do not feel like laying 

 stress upon them, however, because of the short duration of the trial. An extended 

 test of corn silage and roots is planned for the coming winter." 



Effect of fatigue upon the quantity and quality of milk, J. L. 



Hills {Vermont iSta. Bpt. 18U4, pp. 102, 103). — In April 17 cows pur- 

 chased by the station were driven 10 miles, shipped 50 miles by rail to 

 Burlington, and then driven to the station, about a mile and a quarter, 

 where they arrived about dnsk, having been all day on the road. 

 October 8 more were purchased, which traveled the same route uuder 

 similar coaditions. The yield and composition of the milk given by 

 each of these cows on the night of arrival, the next morning, several 

 days later, and 2 weeks later are tabulated. A summary of the 

 averages for each lot is given in the following table: 



Average yield and composition of milk of coics after a journey. 



"The milk flow was lessened by fatigue, the general quality decidedly bettered, 

 and the butter yields increased. Half of the cows gave richer and half essentially 

 the same [amount] of poorer milk on the evening of the day of travel as they g.ive 

 after recovery from fatigue. All gave richer milk the morning following the travel 

 than 2 weeks later, and, with 3 exceptions, richer than the night before. The fat was 

 the most variable constituent, the solids-not-fat remaining quite uniform." 



On the influence of the fodder on the fat content of milk, H. 



Steffen {Dent, hindw. Presse, 23 {1890), Xos. 18, p. 152; 20, pp. 108, 

 109). — The author does not agree with Sebelien's conclusion that there 

 is very little evidence that the comx)osition of milk is affected by feeding.
