ACCORDING to MN. E. and H. Bee
querer, the mean annual temperature of
the soil covered with turf is higher at
the depth of 0.05 meters than that of
similar soil denuded of vegetation by
0.29'.
The cause of the glacial period, Mr..
Searles V. Wood insists, was due to a
lessening of the heat-emittine power of
the sun. Decreased evaporation, he in
s1sts, does not necessarily imply a
diminished snowfall.
DIR. VENUKoFF during his late Jour

HERE Is a geological station to be
established In Java, if the funds are
forthcoming. Dr. SHUTTER has charge of
the matter and will no doubt carry the

The field is good one.
A LATE writer asserts that it is SUD-

III. BARTHELEMEY has studied the de-
velopment of good many eggs laid by
hens suffering from poultry cholera.
None of the chicks Matched from the

bacteria.
DIR. SAMUEL SMILES is the authority

conditions
DIR. 81. MULLER observes that blues.
reds, and certain violets are more at
tractive to bees than other shades

LEATHER may be restored in color, if
not too far gone, by a slight appIica-
ton of oil. If this is not effectual put
on backing, let it dry, brush it off and
go over it again very lightly with oil.
If very brown, black thoroughly and oil

final and careful dressing of gum traga-
canth dissolved in water.
THE citizens of Geneva intend to util-
ize the flow CT the Rhone to furnish
power enough to give electric light to all
of the city. The council of state is to
determine the matter at an early date.
Much natural energy now being dissi-
pated might thus be turned to profitable
account in and near many other cities.
A ToLERABLY successful trial has been
made of an electric omnibus on the Cour

vehicle of this kind can be handled.
notwithstanding its enormous weight.
M. Cookery was present. There is no
probability of machines of this kind
coming Into early use either in Europe

great.
WHEN, says a recent writer, it is de-

man forest leaning tree is selected,
and all the trees in front of it are cut
on one side. Then the vines are severed

ing all the trees near it to the ground
with a crash. Soon the hot rays of the
sun fit the brush for quick destruction
by fire.
