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.
