384 Notes on the Composition of some Samples of Silage. 
The sample taken from the bottom of the silo was too wet, 
and contained too large a percentage of acid to render it a good 
food. The greater part of the soluble matters had been destroyed 
by fermentation resulting in the formation of acids. Any 
alcohol which may have been originally formed appears to have 
been oxydised into acetic acid, and I was unable to detect more 
than traces of alcohol in the liquid expressed from this lower 
portion. 
Description of Mr. Smith's Silo at The Hollies, near Wilmslow, 
Cheshire. 
Circular silo 12 feet diameter by 12 feet deep ; it was filled 
with aftermath on October 20th, and well trodden down, and a 
weight of 100 lbs. per foot was put on for seven days ; the 
weight was then taken off and the grass was found to have sunk 
5 feet ; it was then again filled to the top, and a weight of 
200 lbs. per foot put on. It was opened on January 16th, and 
the contents found in good condition.

The sample was not so good as that from Tatton Park. 
No analysis was taken of the original grass in this case, and 
it is impossible, therefore, to determine to what extent loss by 
fermentation had proceeded. From the low percentage of soluble 
carbo-hydrates and the comparatively high percentage of nitro- 
gen, it would appear that a perceptible loss had taken place : but 
without a knowledge of the composition of the original grass, 
it is impossible to arrive at any decision of scientific value.
