silo No. Two, we feel that we can recommeud the course pursued in 

 filling that silo. As the free acids, acetic and lactic, iu a corn ensi- 

 lage, however carefully prepared, steadily increase after the opening 

 of the silo, as long as unchanged saccharine and amylaceous con- 

 stituents (sugar and starch), are present, it is very important that 

 the access of air should be limited as far as practicable. The decis- 

 ion in regard to the best size of the silo should be largely controlled by 

 the possible rate of consumption. The feeding value of the contents 

 of the most carefully packed silo is apt to be most seriously impaired 

 in consequence of a subsequent prolonged exposure to the air. Three 

 to four weeks exposure altered the character of our ensilage seriously 

 as far as its acidity was concerned. The degree of the change de- 

 pends under corresponding circumstances, largely, on the surround- 

 ing temperature. It is far less during the winter months than in 

 April or May. 



The main portion of both kinds of ensilage was fed to milch cows, 

 in connection with an experiment to ascertain the feeding value of 

 corn ensilage as compared with that of noted root crops. The results 

 of this trial, which extend over a period of from five to six months, 

 will be published in full in a succeeding Bulletin. 



391. ENSILAGE MADE FROM APPLE POMACE. 



Amherst Mill. 



100.00 

 The pomace which served for the preparation of the apple ensilage, 

 was taken from a cider-mill near Amherst towards the close of Octo- 

 ber, 1885, and consisted of the clear press refuse, of a mixture of 

 different kinds of apples. Two casks of a capacity of from fifty to 

 sixty gallons each, were used for the experiment. They were painted 

 inside with a black tar varnish to render them air and water tight. 

 The pomace was stamped down solid, and subsequently covered with 

 tar paper, which was held down by a layer of sand, several inches in 

 thickness, and some large stones. The casks, thus filled, were kept 

 in a corner on the barn floor until May 17th, '86, when they were 

 opened to examine their contents. The material was found through- 

 out apparently as fresh as when put up ; neither mouldy, or rotten, 

 or even discolored on its surface. It had a pleasant fruit-like acid
