 made to conduct similar experiments on a somewhat larger scale again 

 this season. 



Experiments were also made on inoculating corn silage. Fifteen 

 small experimental silos were tilled with freshly chopped corn each silo 

 holding from 250 to 350 lbs. of corn. Dift'erent treatments were given 

 the silos as follows :

Silos Nos. 3, 4, and 5 (glazed sewer tile) containing about 3G0 lbs. of 

 silage were not opened till summer. So far as ordinary organoleptic 

 tests were concerned there Avas no difference among them, all being good 

 silage and relished equally well by the cattle fed. The top G to 8 inches 

 was decayed and had to be removed. Silos Nos. 6 to 17 were galvanized 

 iron cans painted inside with an acid-proof paint. Each was fitted with 

 a removable cover to imitate natural conditions. These were already 

 sunk in the ground, being originally cans used for soil exijeriments. 

 Silage from silos Nos. G to 13 was fed to seven calves in the fall, three 

 to eight weeks after being filled. About one foot in depth had to be 

 discarded because of being moldy (or putrid in a few cases). Neither 

 the addition of the pure cultures used nor of salt seemed to have any 

 influence on the depth at which mold was found. The silage underneath 

 had a normal clean acid odor in all cases, being somewhat more ^vo- 

 nounced in silos No. G and No. 10. Neither the presence of the salt in 

 the various proportions nor of the cultures used appeared to influence 

 the palatability of the silage to the calves. The salt was not laxative in 

 the amounts fed. 



Some bacteriological studies were made of the inoculated silages. An 

 attempt was made to ascertain whether the type of organisms added to 

 the silage still predominated at the time fed and whether they could be 

 recovered. Plates were made on litmus dextrose agar and on acid whey 

 agar, keeping a set of each at 20°, 37° and 45° (J. both anaerobically
