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
certainty within what limits the refuse scum utilization process is to
be recommended. We have great doubts as to the wisdom of introducing
foreign elements, eliminated from other juices in a previous
operation, into a juice fresh from the battery.


OTHER COUNTRIES.

The beet sugar factory in Japan is said to be working with
considerable success.
