month, and found the silo perfectly tight. I 

 then remembered that, before the silo was 

 opened, carbonic acid had disappeared, and 

 that acetic acid had remained in, or continued 

 to come to the top of the perpendicular pipe 

 above the silo. This was proof positive of 

 what had taken place. 



We wash down the walls of the silo with 

 water, using for that purpose a long-handled 

 whitewash brush. This water is all drawn off 

 through the governor drip pipe, and this is 

 what is meant by using the governor to draw 

 off water. We never put water into the forage; 

 the corn contains more than we have occasion 

 to use, and this year (1889) we have been feed- 

 ing as high as 100 pounds daily of juice, but 

 reduced the rations to 50 pounds until the 

 excess of juice was used up. 



The difference in the corn crop between 

 1887 and 1888 was very marked, and accounts 

 for much of the difference in our results. The 

 last year's crop was badly frost-bitten, quite 

 immature, gathered and packed very wet, con- 

 sequently it required much less pressure and 

 gave a much larger proportion of free juice; 

 but the screws and the governor entirely con- 

 trolled these inequalities, and, so far as the 

 preservation was concerned, the result was 

 perfectly satisfactory.
