Western larch has unusually high percent
age of galactan, which it is believed can be con-
verted into fermentabe sugar for use in making
grain alcohol. This galactan in oxidation
yields large quantities of muric acid and muric
acid can take the place of tartaric acid in the
manufacture of baking powder. number Of lum-
bermen recently visited the laboratory and one of
the chemists made baking powder from wood, and
his wife made biscuit with It, Another advance Is
the preparation Of a fine, sweet strip from gaac-
tose a sugar derived from galactan. So II the

with larch strip.
Converting cellulose obtained from wood into

Kraft paper Is made from Sulphate pulp, and
the method Of making 1t came to this country
from Sweden ten years ago. Kraft Is much
stronger than other papers 1t is brown, like what
we usually think Of as wrapping paper. Large
quantities of 1t are used for that purpose and 1t
is particularly suitable for large envelopes. Kraft
is used for book covers, for imitation leather and
for cardboard suitcases. An attempt Is being
made to produce paper Irvine that will replace
the binder twines made from imported
fibers. This question has become more active be-
cause Of the recent shortage of these other fbers
on account Of the conditions south Of us. sue
cessful paper substitute would provide for the
utilization of a large amount Of wood waste and
at the same time build up a home industry indie
pendent of foreign raw materials.
The problems put up to the laboratory to solve
are many and complex. One man In the frog busi-
ness was suffering heavy losses from the death of
his tadpoles. He asked the laboratory to find out
If there anything in the wood which when
washed out poisoned the tadpoles
The government chemists undertook to study
the matter. They could not locate the trouble, so
it put up to the section Of timber tests. After
a few experiments it was found that the resonant
croaking of the large frogs produced vibrations In
the boards Of the tanks. The vibrations were
the tadpoes (they have no brains), causing dis
ease somewhat akin to infantile paralysis.
The remedy was simple. The man was advised
to separate his tadpoes from his large frogs thus
confirming the vibrations to the older generations.
This was done and the mortality among the t,d-
poles decreased wonderfully.
