SCIENCE AND INVENTION.

The German physicians, think that they
have discovered q way to cure the Obsti-
nate hay fever, which has heretofore been
regarded as incurable. They believe it is
due to toxin In the pollen of grasses,
and, have developed serum with which
they have. inoculated animals. and have
gained another which they think will in
stantly cure the burning sensation in the
nose end eyes and stop thenfever. a-"'
Recently Mr.. Raser, OF IAshtabula, o.,
was threa tened with destructive fire on
his farm, from locomotive sparks, and his
horses not being available. he htched his
automobile to plow to turn burrows to
stop the flames. The experiment succeed
ed so well that they are now looking for
ward to the use of automobiles in farm
operations. Successful experiments were
made in blowing fields and moving grass.
the great bearing surface of the tires, the
strong cling of the rubber to the grass and
soil, with the great weight of the machine,
making it good motive power for the
pillow and other farm work.

successful experiment has been tried
in attaching brakes to the Canadian
steamer. Eureka. The brakes are heavy
plates of steel folded against the sides Of
the ship, which are released when it is
desired to stop the vessel. In the trial,
the vessel came to full stop within a
distance equal to her own length. The
brake is also useful in turning.
A. II. Gilmore, of Newport News, Va.
has applied for patent for plan to
place the propeller, wheels or screws, at
vessel. He claims that the device will
produce double the present speed at about
one-half the cost.
II firmly believe" he says. that have
solved the problem of rapid transit by
water. The principle of my invention is
very simple. A cart can be drawn much
more easily than it can be pushed. Now
that's exactly what propose to do to the
steamboat. Don't push it; pull it. 1t will
go much faster ut less expense" The
shipbuilders and mechanics regard the in

from the fight of birds to the building Of
bridges, that weight increases geometrical-
ly, while strength only goes on arithmetic
ally. That is. by building anything twice
as strong, 1t must be made four times as
heavy, and the point is quickly reached In
which the weight becomes crushing For
example. the weight of the engine now re
quired to furnish 10000 horse power to
each of the triple screws, or 10000 horse
power altogether, makes so great a strain
that the vessel is mot able to carry 1t safe
ly, nor are thee boilers and shafts able to
sustain 1t with proper regard to safety
The remedy suggested is the turbine en-
CINE, which is now coming rapidly into
use Builders have offered to build tur-
bine engines for the new Cunard steam
ers which they claim will drive these great
vessels across the ocean, from Liverpool
to New York, in four or FIVE days.
