Americans may still hold the worlds
record, as many maintain, for waste
fulness. but in some
Maxine Rutter industries at least the
advantages of saving
by-products are being appreciated. In
bringing about this better condition Of
affairs the governments various de-
partments. that in one way or an
other come in contact among them with
nearly all Of the country's industries,
are playing important parts. One Of the
contributions of the Department of Ag-
riculture in this movement has been
stimulation Of the manufacture Of
butter from the whey of cheese fac
tories that was previously considered
to have yielded up all the valuable
substances and to be At only for hog
food.
Several years ago the governments
experts, after study of the possibil-
tiles, found that cream could be recoy-
cred by running the whey through a
regular centrifugal separator. They
gave the results of the studies to
large Wisconsin cheese factory and as
sisted in the equipment of the plant
for the additional work. The venture
was successful from the first, and the
other cheese factories Of the state rap
idly entered the whey butter field.
Now tens Of thousands of pounds of
the butter are recovered annually in
the single state. and the industry has
spread to all the other cheese produc-
ing commemorative.
Before the whey is run through the
separatorS 1t has been pretty thorough
ly stripped of its food elements, so that
large quantities are required to pro-
duce an appreciable amount of butter.
The whey from 1000 pounds of milk,
for instance. will produce about two
and a half pounds of butter. The de-
partment experts proved, however that
1t pays to save even this small proper
ton of butter fat. provided the plant
Is large enough to handle as much as
10000 pounds of milk per day.
The whey butter is of good quality.
the Department of Agriculture dairy
specialists find, and has become popu-
lar for table use throughout the cheese
making districts. 1t sells at a price
a trife less than that for ordinary
creamery butter.

vu.,l 1r,.4 has developed a
yellow dye that
bids fair wholly to replace the dye
from fustic wood that has heretofore
been imported in large quantities from
Mexico and South America. The source
of the new dye is the vast volume of
waste Usage orange wood left from the
manufacture of wagon wheel rims, in
sulator pins, fence posts and other
articles.
Because of the irregular form of the
trees there is much material discarded
or pared away in the process of work
ing up the wood, and it is these scraps
ported dyewoods. The waste wood
can be shipped from Texas and Okla
homa, where 1t is produced, and de-
livered at northern Atlantic ports at
foreign fustic costs from $1s to $50
laid down at the same ports. Plans
are now under way for the working
out of a system by which a concen-

Between 10000 and $4,000 tons of

and leather. These tests were made CO.
operatively with number of textile
schools and tanneries, and it was the
decision of all of the experts that the
dye from the domestic wood gave re-
suits equally good as or even better than
those from the imported materials.
