Preserving Green Forage 1 1 3 



a large number of ensilage experts took part, 

 and a phonographic report of which will be 

 read on the first page of the present issue of 

 the Ploughman. It appears that Mr. Colcord's 

 attention was first attracted to the fact that the 

 contents of no two silos or thfc fermentations in 

 them were ever alike. It was by no means 

 certain that, if a silo made good ensilage one 

 year, it would do so the next. From a series of 

 carefully made investigations into this fact, he 

 felt that he had hit upon the discovery of the 

 real cause and its remedy. Out of these ob- 

 servations and this study was evolved the 

 " Silo Governor." His principal object was to 

 prevent the development of bacteria in the 

 process of putrid fermentation. The effect of 

 the governor on the air in the silo, as the 

 ensilage settles down, is to take it out. In what 

 way it is done, the explanation of Mr. Colcord 

 clearly shows; and he adds the highly impor- 

 tant statement that the green forage, under 

 his improvement, comes out without showing 

 any of the usual results of heat and fermen- 

 tation, and, with no destruction to the corn, 

 guaranteed a superlatively good quality to the 

 product. 



In the silo, as generally worked, there is no 

 way for the air to escape except at the top ;
