Corn Ensilage. Two silos of the same size, five b}' fourteen 

 feet, inside measure, and eleven feet deep, were used for the 

 experiment. In both instances the corn was cut into pieces from one 

 and one-quarter to one and one-half inches in size ; they were, how- 

 ever, filled in a different way. 



Silo No. 1 was loosely filled September 4, to about two-thirds 

 of its height, and the mass merely levelled without treading it down. 

 It was left in this condition, without covering, until September 7, at 

 8 o'clock A. M. At this time it had settled from eighteen to twenty- 

 four inches ; the odor of acetic acid acid became slightly perceptible, 

 and the pieces of cornstalk, although sweet to the taste, showed an 

 acid reaction to the test-paper (litmus).

 " 8,8 " " " 12 "

" 8,8 " " "30 " 



" 8,8 " " "36 " 



As the temperature remained practically at a standstill, the filling 

 in of more fr^sh-cut corn was resumed, and the silo completely, yet 

 loosely filled, September 8. A maximum registering thermometer 

 was buried in the mass at a depth of two feet from the surface, and 

 light boards loosely laid upon the top. 

 Sept. 10, 8 A. M. Temperature at 12 inches depth, 129°, 127° F. 

 The mass had now settled eighteen inches. 

 Sept. 11, 8 A. M. Temperature at 12 inches depth, 127°, 129°, 131° F. 

 i' 12, 8 '^ " " 12 " " 122°, 132°, — F. 



The mass had settled from twenty-four to thirty inches. The 

 temperature remained practically the same ; the mass was carefully 

 covered with tarred paper and tight-fitting boards, and subsequently,. 

 on September 12, pressed down with twenty-five barrels of sand. 

 This silo contained eight tons of green corn fodder. 



The temperature observations above recorded were made in differ- 

 ent parts' of the silo ; they show that it is quite difficult to secure a 

 desirable uniform temperature within the mass in all parts of the silo, 

 at the same depth and at the same time. 



Silo No. 2 was filled to a depth of from eight to nine feet, as 

 fast as the cut corn could be supplied and tramped down. As soon 

 as the amount of corn assigned for that silo (9.5 tons) was filled in, 

 the surface was carefully covered with tarred paper and tight-fitting 

 boards, in the same manner as in case of the first silo, and at once 

 pressed down with twenty-five barrels of sand. A maximum regis- 

 tering thermometer was safely buried at a depth of about two feet in 

 the mass, to record the highest temperature which the latter would 

 reach during the time of keeping the silo closed.
