Analyses of Corn and Cob before and after their Treatment 



'in a Silo. 



[1. Corn and cob; cured naturally in the field. 2. Whole com and cob; from silo. 

 3. Cut corn and cob ; from silo.] 



The material which served for the above analyses was sent 

 on for that purpose during the mouth of September, 1886, with 

 the following statement : The different samples were taken from 

 the same lot of corn eleven months ago. The crop was cut 

 when the ears began to glaze. No. 1, whole ears, was re- 

 moved from the stalks and dried in the usual way on the 

 ground ; No. 2, whole ears, was buried at the same time in 

 the silo about six feet below the surface of the cut material, 

 which consisted of the cut stalks and cut ears ; No. 3 consisted 

 of pieces of cue ears of corn taken from the main bulk of corn 

 ensilage at the same time when sample No. 2 was removed for 

 an examination, about eleven months after the filling of that 

 silo. The samples were collected for the purpose of ascertain- 

 insT the character and the deo^ree of chans^e which the ear of 

 the corn undergoes by converting it into ensilage, either whole 

 or when cut into pieces. A comparison of the analytical 

 results shows, what might be expected, that cut ears of corn 

 are liable to suifer a more serious alteration in their composi- 

 tion than whole ears.
