Influence; of tightness of packing. — ^With a full and a three- 

 fourths pack the percentage of bottles which had good silage was 90.9, ' 

 with half pack it was 84.8, and with one-fourth pack it was 75.7. The 

 tightness of packing is an advantage, in that it makes exclusion of air 

 and retention of carbon dioxid more certain. A detailed study of the 

 chemical data obtained showed that favorable development of acid 

 took place if air was kept out. 



Influence of sound corn as a supplement. — ^When the proportion 

 of sound com added to the alfalfa was i to 10, the percentage of bottles 

 having good silage was 100 for the fresh, for the wilted, and for the 

 wilted plus water. When the proportion of sound com to alfalfa was 

 I to 20, the percentage of all bottles having good silage was 75. When 

 fresh alfalfa was used, the percentage was 100; with wilted alfalfa it was 

 50; and with wilted alfalfa plus water it was 75. The results from the 

 proportion of i to 20 are so contradictory that no conclusions can be 

 drawn. Sound com in the proportion of i to 10 is very effective if air 

 is kept out. 



Influence of germinated corn as a supplement. — ^With the pro- 

 portion of I to 20 the percentage of all bottles having good silage was in 

 all cases 100 for the fresh, for the wilted, and for the wilted plus water. 

 The same results were obtained with the proportion of i to 30. With 

 the proportion of i to 40 the percentage of all bottles having good silage 

 was 66.6. When fresh alfalfa was used, none were good. When wilted 

 alfalfa or wilted alfalfa plus water was used, the percentage of good silage 

 was 100. Germinated corn is more effective as a supplement than sound 

 com. If too small an amount is used, the chances of success with fresh 

 alfalfa are no better than if none were used. Wilting is an advantage. 



Influence of molasses as a supplement. — ^With the proportion of 

 I to 20 the percentage of all bottles having good silage was 100 for the 

 fresh, for the wilted, and for the wilted plus water. With the propor- 

 tions I to 30 and I to 40 the percentage of bottles having good silage was 

 in all cases 100, except with the fresh alfalfa, where they were all bad. 

 In general, it may be said that molasses as a supplement has the same 

 effectiveness as germinated com. 



Rye as a supplement. — With the proportion i to 3 the percentage of 

 all bottles having good silage was in all cases 100. With the proportion 

 I to 6 the percentage of all bottles having good silage was 75 ; with fresh 

 alfalfa it was 75, with wilted alfalfa it was 100, and with wilted alfalfa 

 plus water it was 50. In general, it may be said that rye as a supplement 

 was very effective when the alfalfa was wilted. If fresh, the amount of 

 moisture seems to be too large for the formation of good silage.^ 



I "Good silage" as used in this paragraph means that putrefactive odors were absent. The rye, however, 

 imparts a strong, peculiar odor of its own, but this is different from the odors due to putrefactive 

 decomposition.
