Man takes many trips on the face
Of the globe: 1t might be well for him
TO soar beyond the clouds TO observe
the time table and routes of the
spheres and note the relation Of his
earth TO the celestial scheme of things.
When a mighty storm sweeps over
the ocean, when q great war devas-
tates a continent, when Katmaf
blows off her head, when an earth
quake destroys a populous city, men
stand overwhelmed and awed at the
spectacle.
But how little and insignificant are
such forces, measured by the majestic
might OF the earth as ii sweeps on
It's course around the SUM-
An eminent physicist has estimated
that the power developed by a million
Niagaras In a million years would not
equal the energy expended by the
earth in single second as it circles
round the SUM-
And yet so perfect is the mechanism
that, flying around its axis at an
equatorial speed of more than
1000 miles an hour. and around its
orbit at more than LOO miles min
ute, all the mundane influences Of
which astronomers know could not
change the length of its day as much
as a second in 100000 years.
But as soon as one looks out into
space with the eye Of the astronomer,
there comes the discovery that in all
Its seeming greatness the earth is so
small that even a telescope 10000
times as powerful as the strongest in
strument now I'm existence would not
reveal IL 70 an astronomer on any
fixed star.
Compared with the sun, our planets
insignifcance becomes evident. More
than 100000 spheres like ours would
be needed to make a bulk equal to
that of a single sun.
HerschePs Picture of Solar System.
Perhaps our most graphic picture OF
the solar system is given by Herschel.
Imagine a circular field two and half
miles I'm diameter; place n library
globe two feet I'm diameter in the very
center, 50 feet away put a mustard
seed. The globe will represent the
sun and the mustard seed Mercury.
At distance of 142 feet place
pea, and another at 215 feet. These
will represent Venus and the earth,
both as to size and distance. A
rather large pinhead at a distance of
427 feet will speak for Mars. and a
fair-sized tangerine a quarter of n
mile distant will stand for Jupiter. A
small lemon at two-fifths of a mile
will play the role of Saturn, large
cherry tree three-fourths of a mile will
answer for Uranus. and a fair-sized
plum at the very edge of the field
will proclaim Neptune.
Whether studied as the head of the
planetary family to which the earth
belongs. or whether as an average
member of the great household OF suns
that dwell in the distant skies, Old
Sol has many thrills for the student.
To the inhabitants of the earth the
fact that he shines Is the most impor-
From him we derive werath, light
and power; without him the oceans
and even the air itself would freeze !:
and. of course. under such conditions,
life would be impossible.

as much like the sun as the firefiies

All In a Vast Migration.

and their 81 moons. and its 500 aster-
