These results show that the losses, with a few exceptions, were approxi- 

 mately I per cent. The greater part of the larger losses was silage juice. 

 The gas generated in the bottle would push out the stopper slightly, re- 

 sulting in loss. Since the total loss is so small, the losses due to fermen- 

 tation are insignificant. 



MOISTURE CONTENT 



The moisture content in the silage was determined on loo-gm. samples, 

 using the material in the condition in which it was taken from the bottles. 

 The moisture percentages are given in Table II.

The general agreement of these figures for each kind of silage shows 

 that the material in the bottles was fairly uniform. 



METHOD OF MAKING THE WATER EXTRACT OF SILAGE 



When each bottle was opened, 100 gms. of silage were weighed into a 

 quart Mason jar and 430 cc. of carbon-dioxid-free water added, so as to 

 make the total moisture content very nearly 500 cc. Thus, each 5 cc.
