show the fixed stars TO be self-lumnous
bodles-suns to the other systems of
planets. An analysis OF their light indl-
Gates the presence Of the same chemical
elements that exist In our own sun and
earth, together with others unknown In
our solar system.
Where Ice cannot be procured. water
may be cooled by wrapping the pitcher
containing II In n towel OF loose texture
which has been previously impregnated
with ammonium nitrate (and dried and
moistening this with water. The same
towel may be used repeatedly, after be
ing dried each time.
The news from Lick Observatory that
the North star, 255, 100000 of miles
away from us, has been found TO be not
one star, but three-swinginga around IN
great orbits like the moon, earth and
sun--is another remarkable result OF
the application OF spectroscopy
to the telescope study OF the heavens.
An American electric manufactur-
Ing company has been awarded the en-
tire contract for the equipment of nu.
merous electrical plants which will be
installed along the line of the Eastern
Chinese railroad. II Will consist large
ly OF temporary lighting plants. II Isl
thought that ultimately 100000 will
be involved In the contract.
The first century began with the first
day of the year one and ended with the
last day OF the year one hundred. II
could not end with the last day of the
year ninety nlne for one hundred not
ninety nine years make century. The
nineteenth century, therefore, ends Mt
midnight on Dec. 81, 1900, and the
twentieth century then begins.
At a recent meeting of the Geological
Society In London photograph was
exhibited, showing pair of remark
ably large tusks which had belonged

One of the most important American
exhibitions at the Paris exposition will
be model, some twenty feet long, of
the Chicago drainage canal. In con
nectlon with this Will be shown models
OF all the great variety of excavatlng
and conveying machinery which was
used In this important engineering
work. The models will be shown In
operation, and It Is believed that 1t will
he one OF the most interesting of the
engineerlngs exhibitions at the exposl-
ton.
Considerable Importance Is attached
to the distance measuring field glass
invented by Mr. Zelss, of Jena. 1t IL
simply an extension of the natural pow
err of the eyes to estimate the distance
OF nearby objects. This power de-
ponds upon the fact that the space be-
tween the eyes serves like base-line
In surveying, the lines of sight con.
yerging upon selected object from
the ends of the base. In the telemeter
the effective distance between the eyes
Is increased by means OF prisms. and
double images OF the objects looked at
are formed. The distance between the
images varies with the remoteness of
the objects, and scale shows what the
real distance IL. Up to about two miles
the results are said to be fairly NC
curate.
