ing sportsmen in the art of shooting
small game, has been established at
Mans, France, by Mousseaux, a dealer
in firearms. It's chief features is a
circular field, on one side of which
the pupils are stationed, while on the
other side cardboard models are moved
about by special apparatus, and are
made to initiate very closely the varied
natural movements of the animals re-
presented. Rabbits run along the
edge of the field, quail rise suddenly,
and cartridges start up on one side
and then on the other. For beginners
the cardboard targets are given simple
horizontal orvertical motions, but as
skill is acquired the imitation animals
are made to follow very confusing
paths of straight lines, curves and
angles. A system of registering the
hits shows the progress made by the
embyro hunters.
With the diversifying of the uses of
timber, the value of the material is no
longer gagged merely by length and
width and straightness of grain. A
building authority points out that one
industry calls for wood having hard
ness another, for elasticity; and a
third, for ease of working or resis-
lance to destructive agencies. In de-
termining suitability for many pur-
poses, longitudinal and transverse
sections are examined under the COM
pound microscope For the solidlty
and resistance required in much car
pentry. fine grain and thick walled
cells are suitable, and wood showing
poorly defined starch-flled cells must
be rejected.
The Corthesy turbine combines the
use of gas and steam, avoiding the
difficulty of overheating from the
practically continuous explosions. and
augmenting the explosive power by
the energy of steam from the full
amount of heat generated by the ex-

The airship anchor of Capt. Tuchs-
suggested by the disaster to the Yep
pelin passenger airship consists of an
upright shaft with four arms hinged
to it. and opens and shuts like an UNI
brella. 1t can be used where the
ground is sufficiently free from rocks
to permit the boring of hole to 10
feet deep. A good drill makes such a
hole in or 10 minutes, and the closed
anchor is lowered to the bottom, when
a pull on the cable attached to the
airship unfolds the arms and causes
their prongs to take hold upon the
earth. Anchors can be made of any
size, one weighing 125 pounds pene-
trating into the earth about 6 feet
around the hole, and embracing a
mass of earth of weight of 5 to 10
tons. The apparatus is so constructed
that on drawing number Of bolts the
arms can be detached from the shaft
while underground, and in l to 8
minutes the parts can all be drawn
separately from the earth, to be reas-
sembled for use on the next occasion.
Secured only by the bow, the airship
can turn securely on its pivot, keeping
always in the position offering least
resistance to the wind. The anchor is
suitable also for sailing vessels in
shallow water, and may be used for
holding large tents, trees being felled,
and other purposes.
The new ships compass of Com
mandant Heit. French officer, is de-
signed to register automatically the
route over which a ship passes, and
gives reliable evidence of the manner
IN which the helmsman has followed
instructions. By means of electric
contacts. the angle of the vesel's
course with the meridian is recorded
once every minute. A roll of paper is
moved by clockwork so that the time
of each account is accurately re-
Clustered. and chart of the route
traVersed is constantly available for
the captains inspection.
While radium as a cancer remedy has
hardly given the hoped for results, DR..
Louis Wickham of Paris, after treat
ing 600 cases. has concluded that the
substance has real value if not re.
gular cure. The best and most rapid
effects are obtained by combining
radium with surgery. Operations are
made possible that could not be at
tempted formerly, while other advan.
tages are gained, and the experienced
