full flower. The leaf had been well saved and the fodder could be described 

 as "a useful sample of hay, although perhaps uot of the very best 

 quality ^" A mechanical analysis carried out on a representative sample 

 of the hay showed it to contain rouyhly 30 per cent, by weight of oats 

 and 70 per cent, of tares.

Attention has already been drawn to the reasons why the amount of 

 dry matter fed ])or (lav during this ])eriod was smaller than in the pre- 

 ceding period. The liigh percrntage of protein in the hay, as compared 

 with the green forage, must also be noted. It would be expected that the 

 Jiay dry matter would contain rather more protein than the dry matter 

 of the green oats and tares, since, as a result of field fermentation and 

 lieating in the stack, losses of non-nitrogenous organic matter occur.

The increase in the percentage of protein cannot, however, be wholly 

 accounted for in this way, and the explanation is probably to be found 

 in the fact that the hay was not. for reasons already stated, taken from

 regarding the quality of the hay and the silage used in these trials.
