Comparing these analyses with those of the silage at Woburn 
already recorded in this paper, it will be noticed that although 
the silage was supposed to be " sweet " it really was not so, and 
there was nearly as much acid as in that used in the Woburn 
experiments. The fact is that some parts were " sweet " and 
some were " sour." When people make, as they think, " sweet " 
silage, there is generally great variation in different parts of 
the silo, some portions being sweet and others sour, some wetter 
and some drier. 
Though, as it is almost needless for me to say, analyses 
do not in themselves accurately represent the differences between 
good and bad hay, nevertheless it will be readily noticed that 
the Wilmington hay contained a decidedly larger proportion of 
indigestible woody matter than the Woburn hay. As a matter 
of fact, while the Woburn hay was of very fair quality, that at 
W^ilmington was very inferior indeed, the land off which it 
came being poor. The silage on the other hand was really 
well made ; there was no great amount of loss by moulding ; 
indeed, comparing the silage and the hay in this particular 
case, I should not hesitate to describe the grass as having 
produced better silage than hay. A reference to the analysis 
will also show that whilst in the Wilmington hay there was so 
much more woody fibre than in that used at Woburn, the silage 
on the other hand did not contain mora. I must not place too 
much reliance on this, owing to the grass not having been 
sampled beforehand, but I mention it as perhaps in some way 
explanatory of the feeding result. 
The amount of increase in the bullocks was small, and con- 
siderably below the Woburn average. At the conclusion the 
beasts were not nearly fat, and were very wild upon being 
turned out. 
The experiment as a parallel one has been of considerable 
interest, and to Mr. Evans much credit is due for the care and 
attention which he gave throughout, and for an example set, 
which, if followed by others, would be of much aid in the cause 
of agricultural research. 
XVIII. — Sheep-Feeding Experiments conducted at Crawley Mill 
Farm, Woburn, in the Winter of 1886-7. By Dr. J. Augustus 
VoELCKER, B.A., B.Sc, Consulting Chemist to the Society, 
During the winter of 1885-6, I carried out at Woburn some 
experiments on sheep-feeding, with the object of getting infor- 
mation upon the value of cereals, especially wheat, as com-
