the earth very slowly and that thin
covering of soil is sufficient to pro-
tect even explosives aud inflammable
liquids from the highest temperatures
Of burning buildings. IN tests OF the
fire department of Hanover, Germany,
three fiat piles were made of dry
sand, slightly moist gravel and build
ing debris, the sides having slope
of 40 degrees and the top of each be-
ing large enough for a furnace -
inches high of brick walls. Coke
fires we're maintained for several
days, Ihe heat at the base of the
furnaces was estimated at more than
210O degrees, but the rise in tempera-
ture was slight in the piles of fill,
even after several days, and at a
depth of 40 inches only 100 degrees
f.. was reached after As hours, this
being about the boiling point of
benzine. In the pile of building
deris these were the temperatures
after u hours. At 4 inches of depth,
5lS degrees f., II inches, lS5 degrees
20 inches, 122 degrees; 80 inches, 90
degrees; az inches, 63 degrees.
The reason why the stomach and
intestines do not digest themselves
was once thought by WeinIand. a
German eXpeIimenter, to be that
they defend themselves by anti
engines, or anti-ferments. DR.. Nan
dor Klug, of Budapest, now reports
these anti -ferments not to be found,
but that the mucln present in the
inner half Of the gastric mucous mem
brane resists the digestive action of
the trypsin and the gastric juice.
The digestive organs, therefore, pro-
tect themselves by the mucin they
secrete.
To lessen risk of loss of submarines,
torpedoes used in naval practice and
other objects liable to sink IN the
sea, French oceanographer attaches
a vessel of oil having a long and
short tube Ito of an inch in dia-
meter. When submergence softens
the gum seals of the hes, oil rises
from the long one drop !. by drop,
) locating the sunken object by the
film on the water's surface.

dens, i'll London, aud Mr. Il. II.
IhwaIte points out that the triple
combination of water screened arc
light, electrostatic stimulus and high
~ fertilizing atmosphere can be con
trolied in a wide range of experiments
to show the maximum acceleration of
growth and the highest quality of
product. The necessary heat and
actinic light, as we'll as carbon dioX-
ide, moisture and nitrogen fertilizer
in the form Of ammonia sulphate, are
all derived from coal. Perfect COM
bustion is insured by bringing the
fuel into gaseous condition by a
suction gas producer, and gas
engine gives power Tor electrical
energy, while the water from the
cylinder jacket supplies heat for the
glass house, and the exhaust gases are
led through earthenware pipes to the
plants, furnishing carbon dioXide,
+ water vapor, oxygen and nitrogen in
heated condition. The power, heat,
: moisture and gases are easily con-
I trolled. The arc lights, with hood
!, and water-screen are slowly moved
, to and fro along the entire length of
, the glass house, and an electrostatic
n as we'll as the air.
s The steam consumption meter pat

n small electric alternator, with a
b magnet wheel built into the steam

}. fitted to its periphery. The current

n voltmeter the pounds of steam con
sumed per hour, or IA train Of wheels
can be arranged to give a continuous
n record. Connection to the pressure
@ gauge gives variations in the resist
o ance of the voltmeter circuit, and
k thus automatically oorrects for varia
h tions in steam pressure.
