l)rotciii and more fibor than the hay usually employed by us 

 for digestion experiments. 



The young sheep (Period IV.) did not digest the hay as 

 fully as did the old sheep (Period V.) The experiment was 

 repeated with two of the young sheep in Period XII., in 

 which case higher coefficients were obtained, though they 

 did not equal those secured with the old sheep. The hay 

 showed a fair digestibility, and no extreme variations were 

 noted among the several sheep in the same trial. The re- 

 sults, however, do not agree as closely as most of the former 

 experiments with hay carried out at this station. 



Bihbi/s Dairy Cahe, made by J. Bibby & Sons of Liver- 

 pool, Eng., is composed principally of ground cotton-seed, 

 cereals such as barley and wheat, molasses, fenugreek and 

 salt. It has a pleasing taste and smell, and appears to be 

 highly relished by farm animals. The results of two distinct 

 trials are reported, the fii'st made during the winter of 1903 

 with three old sheep, and the second made during the winter 

 of 1904 with three young sheep. The first sample was pur- 

 chased from the stock of a retail grain dealer, and the second 

 was obtained directly from a recent importation. Both lots 

 were in good condition, and resembled each other closely in 

 chemical composition. In the second trial the cake was not 

 relished by Sheep III., although he was induced to eat it 

 after a few days. The cake, which was ground before being 

 fed, acted as a laxative, at first producing soft faeces, which 

 gradually hardened as the period advanced.
