WASHINGTON, May 22.-Sccreta'
ry Houston of the department Of ag
riculture says that his experts have
secured a practical method of prevent
ing the unnecessary waste OF con
demned milk, a fact which will be Of
material benefit all over the country,
and be appreciated by farmers and
others.
He tells us that 1t is teh custom
of officials in many, cities to condemn
milk because Of the failure Of the
milk dealers to comply with certain
temperature standards. Usually this
milk is disposed of by emptying it in
to the gutter, although some attempts
have been made to %oenature the milk
by adding some substances which
would make it unfit for use in its
fluid state.
1t is unfortunate that this milk,
which is valuable for feeding farm an
inals, should be needlessly wasted.
This loss a be prevented If the milk
is returned to farms where it can be
utilized for making casein, and for
other purposes.
The dairy division of the bureau
Of animal industry has recently con.
Quoted some experiments in order to
devise a practical method of denat-
uring milk so that It's sale as mar
ket milk may be prevented and yet
leave it in a condition suitable for
feeding farm animals. The work
thus far proved that the use of a rem
net solution is effective for this pur-
pose at the usual temperature at
which milk is condemned.
In these experiments a 3 per cent
water solution made from powdered
rennet of a strength of l to 10000
was used, and 40 cubic centimeters
of this solution were added to 5-gallon
cans of mix at different tempera-
lures. The tests made in a
room where the temperature was 50
degrees F., as that is about the tenn
perature of the air ir summer when
most of the milk is condemned.
In n test the rennet solution was
added to a 5-gallon can OF MIX at 2
temperature of so degrees F. In l
hour and 10 minutes the milk was
slightly thickened, its temperature
then being 81 degrees F. Thirty min
utes later the temperature was SO de-
grees and a soft curd formed. An
equal amount Of milk at an initial tenn
perature of IS degrees was treated at
the same time. In l hour and 10 min
ties the milk in this can was firmly
coagulated, and it is probable that the
rennet had produced the desired eff.
fect in much less time. At the end of
his period the temperature had been
'aised only IL degrees, or to 66.2 de.
srees F.
In. the light Of these experiments,
It is believed that if a rennet solu-
ion Of this strength is added to con-
demned market milk, satisfactory re-
suits can be secured under ordinary
conditions without the disadvantages
the other methods which have been
If a 3 per cent solution is made
from rennet, strength of l to 10000,
about 2 IL ounces ESQ cubic celtime-
:ers) of this solution will be required,
for a 10.gallon can of milk lat q tenn,
perature Of SO degrees or higher. The
cost of the material for this method
Of denaturing is very small, being on
~ about three and one-third cents for
1O-gallon can when powdered rem.
net costs 81 a poud.
Secretary Houston recommends
that those who contemplate using this
method should test their solutions in
he laboratory before using them in
practice, sc as to know definitely the
strength OF each solution prepared. b
1t is something to know in these
days when the high cost of living is
a hubbub all over the land,
that, according to a statement of Sec
Redield Of the department of
the total value of the i'm
ports of such Injuries as art works,
laces, perfumeries, feathers, precious
cigars, wines, and things of
hat sort for the fiscal year that will
end on June 80, 1913, will be greater
than ever before inthe history of the
United States, judging from the Off
cial figures for the nine months that
ended with March, 1913. FL; ..,
The value of art works imported
the first 9 months of the cur.
rent fiscal year is over $50, 100000, as
compared with less than 80 million
Tor the corr sponding months Of last
year, and about 20 millions in the
same months of last year, and about
20 millions in the same months of
1911 and 1912. That's a new and a
startling record. ~.......
1mportations of diamonds and other
precious stones footed up IS million
dollars this year, as against 80 mil
lion in each of the two preceding
years. This total has been exceeded
in 1910, when the importations
we're abnormally large by reason OF
the very light importations of 1908
and 1909.
Laces, !embroideries and, other arti.
cles of this class show a total for the
