The rotation of the earth determines
the length Of the day, and may be re
garded as one of the most important
elements In astronomical science. II
serves az universal measure Of time,
and forms the standard of comparison
for the revolutions of the celestial bod
les, for all ages past and to come.
1t is proposed to project thirteen
inch stream of light from the sea to the
sky, which will be visible forty miles
away. The electric lights on the light
ship now on Diamond shoal can only
be seen thirteen miles. The search
light apparatus will be arranged be-
tween the two mastheads. and the roll
ing Of the ship will produce a distinct
i've waveriDg light to be reflected from
The sky.
An important announcement was
lately made by l.. O.. Howard. the Unit
ed States entomologist, of the discOv-
cry OF the long sought original habitat
of the San Jose scale insect. This was
found to be in China, in the region to
the south of the Great Wall. The scale
insect was preyed upon by species
of ladyblrd beetle, living examples Of
which have been imported. to be prop
agated and distributed.
Professional divers, who remain I'M
der water from two to five minutes at
IA time, are accustomed, before sub
merging themselves, to take deep in
SEPARATIONS for ten minutes. The object
is said to be to store up oxygen, not In
the hung cells, but in the blood-corpus-
cles. This renders temporary sus-
pension of the breathing possible by
supplying the corpuscles with an extra
quantity of oxygen, to be exchanged
chemically with the carbonic acid, pro-
dnced by vital processes, In the blood
On the loftiest mountain in Germany
the ZugsptZe, In the Bavarian Alps,
9.275 feet above sea level, Is an import
ant meteorological observatory, which
is occupied all the year round, but In
winter is cut off from communication
with the lower earth because of storms
that destroy the telegraph and tele-
phone lines. Recently a wireless tele-
graph installation has been made at
tie observatory, connecting It with
the postOffice Mt Eibsee in the valley,
three miles away. The observer In his
lofty perch is thus made Independent
of the storms for the wind has no eff

his messages.
A recent chemical examination of the
black deposit resembling boiler scale,
that has formed to thickness of three
quarters of an inch under the coping OF
the balustrade surrounding the "Stone
Gallery" at the base of the dome of st.
PauPs Cathedral, reveals the curious
fact that it is essentially calcium
sulphate collected from the air. In two
centuries the smoke and gases from
London chimneys have charged the
rains with sufficient sulphurous and sui
phuric acids to cover the stone with a
deposit that strikingly resembles calca-
reous tufa 1t Is thickest on the under
side of the copings because of the drip
ping of the rain. faA f9m NJ f.d
A Danish engineer, III. G. vogt, Of Co
penhagen, has invented propeller for
ships that attempts to initiate the ac-
ton of fish's tail, and combines driv-
ing with steering power. Experiments
are said to have shown that the new
apparatus, which is called the 'pendu-
lum propeller" gives a greater driving
thrust than does the screw propeller,
while it's steering ability exceeds that
attainable with. twin-screws and helm
together. The great difficulty is with
the engine. for, with present forms of
engines, the weight Of the driving
mechanism Is too great to be practica.
