The results are also given of the determination of tlie coefticients of 

 digestibility of jxiorly cured clover and timothy hay by two grade 

 Devon stei'rs, which were fed from April '.»to 17 exclusively (tn lliis

 containe<l a laige proportion of clover. The sea.soii was wet and the 

 growth of the grass was very rank so that it lodged. The hay was 

 cut late and was wet while curing." The composition of the hay is 

 given. The coeflicients of digestibility found were as follows:
