To compare with the above table, the pH values of the silage from 

 several silos including the respective silos from which the above cul- 

 tures were isolated is of interest. The pH determinations were made 

 on a 1-10 dilution. 



•One week after filling the silo. The second determination was made a month after filling. The pH values of silos 7, 8 and 9, 

 were determined after at least a month of ensihng. 



Comparing the acidity of the silage and that produced in the sugar 

 broths by various organisms, it is fairly easy to pick out the organisms 

 which may have influenced the pH value of the silage. The most active 

 and general acid producers are being saved for experiments in silage 

 inoculation to be carried out later in the season. [Zae Northrup Wy-
