It is believed that 15 pounds of hay and 18 pounds of grain, of which 

 velvet bean feed constituted some 3 pounds, were sufficient for the work 

 the horses did from week to week. It is possible that during a few days, 

 or for a week at a time, the nutrients were not sufficient. The other ration, 

 consisting of 18 pounds of hay and 20 pounds of grain, probably was more 

 than was needed. 



The horses ate the ration, of which velvet bean feed comprised some 18 

 per cent-, continuously for over three months, and the results were in 

 every way satisfactory. 



D. Linseed Meal as a Grain Supplement for Horses. 



Beginning September 1 the two horses Torft and Joe were fed a grain 

 ration composed by weight of 100 pounds of whole oats, 160 pounds of 

 whole corn, and 30 pounds of old process linseed meal. Tom received 

 daily 20 pounds of the mixture and Joe 19 pounds, in addition to 18 

 pounds of hay. This ration was continued until September 28, when it 

 was slightly modified by decreasing the linseed meal to 20 pounds in the 

 mixture, or about 7 per cent. The reason for the reduction was that the 

 linseed did not mix evenly with the corn and oats, owing to the fact that 

 they were not ground or crushed; hence considerable would separate out 

 and the horses were inclined to leave a little. Horses do not seem to care 

 particularly for the linseed if fed unmixed, but will eat a reasonable amount 

 readily if constituting a part of a mixture. This ration was continued 

 until November 11. The horses did regular farm work during this j^eriod, 

 but did not average as many hours daily as earlier in the season, and the 

 work would be considered only moderate.
