, if cows eat only 7 per
cent. of their weight, considerable fattening follows. Consequently,
while beet refuse, after long keeping, loses 50 per cent. of its
weight, it appears in the end to be more economical for feeding
purposes than fresh cossettes direct from the battery.

During this period of keeping the percentage of water remains nearly
constant; fatty substances which were 0.08 per cent. become 0.74; and
the percentage of carbohydrates diminishes. Chemists are unable to
explain the changes that have taken place; if they are desirable, as
they appear to be, judging from the practical results just cited,
there is this question to be solved: What future have dried cossettes?
Evidently they offer advantages, as no one can doubt, such as a
decrease in weight and bulk, easy keeping for an indefinite time, etc.
At present, there is building a silo to contain 4,000 tons fresh
cossettes; this is to have the best possible system of drainage.
During the coming season it is proposed to analyze the water draining
from this mass of fermenting refuse; and we may then learn more than
we now know about the chemical changes above mentioned.

A correspondent of M. Sachs asks why it is not possible to use live
steam in defecating tanks. A simple calculation shows that the water
to be subsequently evaporated would be increased 10 per cent. This
evaporation would cost more than cleaning of copper coils, etc.,
combined with other difficulties existing appliances offer.

The question as to the most desirable number of beets necessary to
analyze to obtain an average has been in part settled. Factories
working 500 tons per diem should make at least 200 analyses of beets
received, which work offers no difficulty by the rapid methods now
used. Several samples should be taken from every cart load delivered,
then make average selections from the same.

RUSSIA.

Weak currents of electricity, 0.03 to 0.04 ampere, have been passed
through sirups for fourteen hours without any special increase in
purity coefficient. Experiments made upon diluted molasses or with raw
beet juices were not encouraging.

Mixing of filter press scums with diffusion juices is said to offer
special advantages for the preliminary purification. Not over one to
two per cent. of scums should be used. If in too great quantity, the
raw juices will yield inferior results. During operations that follow,
experiments are not yet sufficiently advanced to determine with
