EXPERIMENT STATION REPOET. 287 



As soon as help could be obtained the fodder corn was 

 harvested and put in the silo, the cutting to 1^ inch lengths 

 being done by hand-power. 



15212.5 pounds were cut and put in the silo Sept. 6; 

 13850.0 pounds were cut and put in the silo Sept. 7 ; and 

 5327.5 pounds, harvested the preceding day, were cut and 

 put in the silo Sept. 8. The total of green fodder was 

 17 tons 390 lbs. 



The corn was well tramped down as it was put in the 

 silo, and at night when work was stopped the surface was 

 carefully levelled and left without covering until morning. 



The night of the 6th the mass settled about two inches, 

 and on the niijht of the 7th it settled three inches. 



The cover was put on and weighted with earth to give an 

 estimated pressure of something over 60 pounds to the square 

 foot, in the afternoon of the 8th. 



The mass, before covering and weighting, filled the silo to 

 the depth of 8^ feet, and the temperature two feet below the 

 surface was 82° F. 



Temperature. 



For the convenience of future observations a gas pipe 1|^ 

 inches in diameter and four feet long, with sharp edges, was 

 driven through a hole in the middle of the cover, and the 

 upper end was securely packed to make a tight connection 

 with the planks of the cover, while the top was closed with 

 a plug. 



The temperature of the ensilage at the bottom of this tube, 

 and the temperature of the air outside, together with the 

 settling of the surface of the mass of ensilage, were fre- 

 quently observed with the results given in the following 

 table. Whenever a change in the temperature was noticed 

 the observation was immediately repeated, to eliminate all 

 possible errors. The observations on the depth of ensilage 

 were taken from a single point until the 18th inst., when 

 irregularities in the rate of settling were noticed, and the ob- 

 servations were afterwards taken from four points, the aver- 

 age of them being given in the table : —
