The new boat Of NJ. Turc. of the
French navy, designed to pass through
the waves without roll or pitch is
described as a combination of sub
marine and high platform. The sub

seventy-five feet wide and twelve feet
deep, and is to contain boilers, engines
and steering gear, which will be sub

From the submarine will rise vertical
ly two floaters, sixty-five feet apart,
each two hundred feet long and ten
feet wide.
In addition to an eight-inch disap-
pearing gun, firing a light projectile
by compressed air, there is, in an
armory of the National Guard in
Brooklyn, a model of a ships cutter,
carrying a crew Of ten men and one
FOUNDER gun, and running on concealed
wheels, which are driven by means
Of a rope attached to the oars. A
rudder-post is geared to a guiding
wheel in the stern, so that with oars
swinging and men bending to their
work, the boat glides about the armory
floor, and looks, in partial darkness,
as if it were genuinely atioat. The

A scientific investigation of muscular
fatigue has been begun by NJ. A. NJ.
Bloch. From questions sent to per-
sons of many occupations he finds
that it is not the most used muscles
that are most subject to fatigue, but
those that are kept under tension, al
though doing no WORK. The back,

strengthen them, the arms and legs
less. The baker becomes first tired
in the legs, the wood sawyer in the
calves of the legs or the loins, the
road-digger in the legs, the blacksmith
in the back and lOins, the young soldier
re back of the neck. the hOrseman
in the thigh. the artilleryman in the
neck and lOins, the immature viOlinist
in the neck, the practiled violinist in
the left hand, the expert fencer in the
right shoulder, the oarsman in the
calves and insteps.
The department of agriculture has
undertaken a series of experiments in
tended to answer, if possible, the old
question, How long can seeds remain
buried in the soil and sill retain their
power Of termination" Many extra
ordinary stories have been told of the
prOlongation of the vitality of seeds
during many years, and even centur
les, but very few actual experiments
have hitherto been made. In 1901
Doctor Beal reported that he had
found seeds which responded to germ
nation tests after having been buriet
twenty years. The seeds buried by the
agricultural department at the Airing
ton farm last December were packed
with dry clay in porous clay pots, GOV
cred with saucers, and placed at vari
Gus depths. from six inches to three
and a half feet. There are 30 complete
sets, in 3,5S4 pots. representing 1O|
