496 Rej)ort on the Experiments on Ensilage conducted at 
year's experiment in the making of silage at Woburn, and that 
the grass which was used both for making hay and silage was 
not in a condition nor of a quality likely to produce really 
good silage. I am therefore not prepared to take the experi- 
ments of a single year as decisive. Nevertheless, the experi- 
ments have undoubtedly shown this : that inferior grass, such 
as I must call this, will never make a food at all able to compare 
in feeding-value with roots and hay containing as nearly as 
possible the same amount of essential feeding-constituents, even 
if the hay be made from the same grass as the silage. The 
clover was, however, thoroughly good ; and with it, too, the same 
feeding result was obtained. I have abstained from going into 
the question of the chemical losses sustained during ensilage, 
having myself only taken in hand these experiments a con- 
siderable time after their commencement ; but I hope to do 
this in a future year. 
Silos 1, 2, and 4. — Silo 1 was intended for " sour " silage, and 
Silo 2 for " sweet" silage ; but, as the appended analyses show, 
the distinctions could not be traced, nor was there anything 
like uniformity among the different samples taken from the same 
silo. It is probable that in Silo 2, though the temperature rose 
higher than in Silo 1, it was never high enough throughout the 
entire mass to render it what is termed " sweet " silage. The 
dry state of the grass also had in all likelihood much to do with 
the imperfect souring of No. 1. No. 4 silo, on the other hand, 
the material of which was much wetter, was decidedly acid, and 
the temperature did not go above 91° F. This silage kept very 
much longer free from mould than either of the others, they 
turning soon bad. On cutting out some of the silage and 
inserting a thermometer in the mass, it registered 120° to 
130° F. in the case of Silos 1 & 2, but only 58° F. with that of 
Silo 4, the silage keeping quite cool. A cubic foot from No. 1 
weighed 22 lbs., from No. 2, 16 lbs., and from No. 4, 38Jbs.
