About $50 tons of ore have been used
to produce about one-fifth of an ounce
of radium.
To test the mosquito theory Of ma
laria, two French physicians propose
to be bitten by mosquitoes fed on an
ague patient, and to allow any fever
contracted to run its full course with
out treatment.
In some of the French forests a
platinum wire kept at a white heat by
an electric current has been employed
instead of saw for telling trees. 1t
is claimed that by this plan tree can
be felled in one-eighth of the time re-
quired by the old saving method The
entire absence of sawdust and the ben
eficial effect of the slight carbonization
of the ends of the cut timber in pre-
serving the wood are reckoned as de-
cided advantages.
An interesting method OF protecting
peach trees from frost during the win
ter has been practiced for several
years at the Agricultural Experiment
Station at Canyon City, Colo. Early
In November the earth is removed
from a circle about four feet in diane
ter round each tree. and water is
turned in to saturate the shoil When
the ground has become soft the tree
is worked back and forth to loosen the
roots, and then is pushed over on it's
side. The branches are brought to-
60,
burlap covered with earth is put over
them. Thus the trees lie all snug until
spring, when the covering is gradually
loosened and finally removed, and they
are raised and propped up.
Among precious stones the turquoise
holds peculiar place because of the
changes of color which it undergoes.
United States Consul Tyler at Teheran
is eloquent in his description of the
Persian turquoises in recent report
TO the Department of Commerce and
Labor. Students of Shakespeare read
ing it will recall Shylock's exclamation
when Tubal tells him of a ring that
his daughter Jessica has given away:
"Out upon herl Thou torturest me,
Tubal. 1t was my turquoise. l had it
of Leah when l was bachelor" Mr..
Tyler AYERS that Notwithstanding its
so-called sympathetic changes of hue,
every genuine turquoise possesses a
permanent color, to which it settles
down with age. 1.-The lapis lazuli, or
cloudless sapphire of its native skies, "
he says, sis the highest quality of the
turquoise" Travellers are frequently
deceived by inferior stones.
While the French submarine boat
Narval was leaving Cherbourg Harbor
recently, she came into collision with a
tugboat which was travelling at right
angles to the course of the submarine.
The officer of the latter observed the
approaching tug and Immediately re-
versed his engines, the Narval at the
time making a speed of five knots.
Although the momentum of the sub
marine was thus considerably reduced
she struck the tugboat with sufficient
force amidships to force her nose
through the hull of the latter to the
extent OF sixteen inches and the tug
ultimately foundered, when the nose
of the Narval was withdrawn. This
accident affords a conclusive estimate
of the strength and power of these
submersible craft for ramming pur
poses, when driven at full force
against another craft; and, according
to French Admiralty experts. opens
new possibilities concerning naval tao
tics.
