• Id 18S9, at the New York Experiment Station, at Geneva, some experi- 

 ments were carried on with the King Philip corn. Cuttings were made 

 July 30, August 9, August 21, September 7 and September 23. The 

 yields of dry matter per acre at the different dates were respectively: 

 .81 tons; 1.54 tons, 2.33 tons, 3.63 tons, and 3.96 tons. At the latter date 

 the corn was fully ripe. There was, therefore, a continuous increase in 

 the yeilds of dry matter per acre up to the time when the corn was fully 

 ripe. (New York Agricultural Experiment Station Report for 1889, 

 page 87.) 



In the same experiment it is shown that the yield per acre of albumin- 

 oids increases even after the ears are glazed. 



In Bulletin 68, of this Station, published in 1889, it is shown that the 

 yield of dry matter per acre increased very materially up to the time 

 when the corn was about all glazed, when the ears were hard and the 

 stalks nearly dry. 



On the question of the changes that take place in the silo, many ex- 

 periments have been performed by experiment stations in the northern 

 United States, as is shown by the following table, which reports the 

 results of some of these tests:

In the Wisconsin Report for 1895, page 273, this statement is made: 

 "It thus appears, from a consideration of all the data here presented, that 

 the necessary loss of dry matter in corn silage is considerably less than 

 ID per cent, and is probably as low as five to eight per cent." 



In the report of the New York Station for 1892, page 162, .it is shown 

 that the loss in the silo was studied in three experiments with corn 

 fodder and three with sorghum. The average loss for all amounted to 

 L2.6 per cent of dry matter, 18.5 per cent of the albuminoids, and 26.6 

 per cent of the starch and sugar. 



The losses in our experiment in 1897 were somewhat in excess of the 

 average of these figures derived from the reports of other Stations. This 

 is due largely, if not entirely, to the fact that our silos were smaller 

 than those used in practical stock feeding. The surface exposed at the 

 sides and top were relatively much larger than would be the case with 

 larger silos, aDd the losses are correspoDdiDgly greater.
