"A preliminary estimate by the geo
logical survey puts the, country's~ pc
troleum production for 1908 at between
l75.ooO,ooo and 1so.ooo.o0o barrels, as
against 166,oOO,0OO barrels in 1907.
The white rhinoceros which Presi.
dent Roosevelt is expected to try to
shoot while in Africa really Is of
yellowish color, not so much lighter
than its commoner relatives. but 1t Is
larger beast.
According to two scientists of the
Massachusetts Institute Of Technology,
each human emotion creates In deli
cate machine which they have invent
ed distinct electric force which 1t is
possible to classify.
The. blackening of the glass of incan.

although the fusing point Of carbon is
in the neighborhood of 1000 c., 1t be-

A writer in the London Times sug.
gests way in which an instantaneous
photograph of the wheels Of passing
auto may give measure Of its speed.
With the focal-plane camera shutter
the slot moves in such way as to dis
close first the part of the wheels which
touches the ground. Since the upper
part OF the wheels is moving with
twice the velocity of the car, and the
lower part is relatively stationary, the
effect in the photograph is to distort
the image ola wheel into an elliptical
form whose shape varies in accordance
with the speed. Hence, If the time
movement Of the shutter Is accurately
known. the speed of the passing car
can be quickly deduced.
The quantity of light which 1t Is
now possible to obtain. at reasonable
cost. from tungsten lamps >in series,
has led to an innovation in street
lighting in some Michigan towns,
which. 1t is thought. may find wide
adoption. In Grand Rapids, where the
system seems first to have been ap-
piled, the tungsten lamps are strung
across the street. between the caves
Of the buildings, in such a way that
they form the outline Of an arch. The
effect Of series of these Illuminated
arches resembles that of a canopy
Of lamps covering the street. and shed.
ding down upon 1t a pleasing illumina.
ton. The same system has been adopt
cd in Big Rapids. and is under consid-

Prof. George Forbes has given new
life to the belief in the existence of an
unseen planet beyond Neptune. He
bases his conclusions In favor Of the
reality of this planet on the peculiari-
ties Of four remarkable comets. sup.
posed to be intimately related to one
another. These are the comets Of
1856. 1913. 1880 and 1882. Prof
Forbes idea is that the comet of 1855,
which was described as of ''prodigious
magnitude" and which Is said to have
led to the abdication of the Emperor
Charles ". was disrupted by the infu.
.ence Of the supposttitious planet. and
gave birth to the three other comets
named, all of which were very bright
and otherwise remarkable His cal.
culations indicate that the planet in
question is situated at distance of
about 9,0O0,00O,00O miles from the sun.
and that It's period of revolution Is
about 1000 years.
