The following year, in a somewhat similar experiment, the same 
authors (13) find a loss of 18 per cent of the dry matter, 11 per cent 
of the albuminoids, and 26.5 per cent of the sugars and starch of the 
green maize during ensiling. 
Two years later Hills (14) reports a repetition of the investigation 
of the comparative losses in maize silage and maize fodder and gives 
a more detailed chemical report. He states that he found losses in the 
total amounts of the different constituents of the maize from harvest- 
ing to feeding to be as follows : Dry matter, 20 per cent ; crude pro- 
tein, 12 per cent; crude fiber, 5 per cent; nitrogen-free extract, 30 per 
cent ; ether extract, 16 per cent ; and a gain of 3 per cent in crude ash. 
The director of the New York Experiment Station (15) at Geneva 
reports investigations extending over a period of three years, during 
which nine bags of green maize and seven bags of green sorghum 
were buried in a silo 14 by 15 by 30 feet. The bags weighed 50 pounds 
each at ensiling and, except for one bag of sorghum, were buried in 
sets of three, one bag at the center and the other two within a foot of 
opposite walls of the silo. The combined results of the 16 bags show 
during ensiling the following changes, which are based on the total 
amounts of each constituent of the maize ensiled : Losses — water, 3.9 
per cent ; ash, 0.4 per cent ; albuminoids, 18.5 per cent : crude fiber, 9.8 
per cent; nitrogen-free extract, 15.1 per cent; albuminoid nitrogen, 
18.7 per cent ; sugars and starch, 26.6 per cent ; and dry matter, 12.6 
per cent ; grains — crude fat, 45.4 per cent ; and amide nitrogen, 3.7 
per cent. 
Clements and Russell (16) state that they ensiled green maize in a 
round silo 12 feet in diameter and 17 feet high and examined the 
silage a few days and also three weeks after ensiling. Their tables 
show a loss in protein nitrogen and a gain in amide nitrogen, also a 
slight gain in fiber and in furfurol, and they seem to indicate no trace 
of sugars remaining even after a few days' ensiling. 
Russell (17) gives a summary of the investigations undertaken with 
maize silage over a period of five years at the South-Eastern Agricul- 
tural College, Wye, England. He concludes that the characteristic 
silage changes are the disappearing of sugar, of some of the less 
resistant cellulose, and of a part of the protein. 
Annett and Russell (18), in a very interesting paper published 
in the Journal of Agricultural Science in 1908, give a discussion 
of various phases of silage investigation undertaken at the South- 
Eastern Agricultural College, Wye, England. They discuss quite 
thoroughly the losses and changes in the silo. Each year the in- 
vestigators buried in a 12 by 17 foot round stave silo several sacks 
of from 10 to 15 kilos of fine-cut corn at different depths, and 
analyzed the maize when put in and when taken out of the silo.
