cluster 50,000 stars are
shown in an area of sky which would be entirely covered by the full
moon.

Hercules occupies the part of the heavens toward which the sun is
bearing the earth and planets at the rate of twelve miles a second or
373 million miles a year.

On a clear night the asterism Cerberus, the three-headed dog, which
Hercules holds in his hand, can be seen.

This constellation is said to have been an object of worship in
Phoenicia. There is a good deal of mystery about its origin. The
ancient Greeks called it "The Phantom" and "The Man upon his Knees."

The stars [e], [z], [[^e]], and [p] form a keystone shaped figure that
serves to identify the constellation.

BO[:O]TES (b[=o]-[=o]'t[=e]z)--THE HERDSMAN, OR BEAR DRIVER. (Face West.)

LOCATION.--Bo[:o]tes lies just west of the Crown, and east of Cor Caroli.
It may be easily distinguished by the position and splendor of its
principal star, Arcturus, which shines with a golden yellow lustre. It
is about 35[deg] east of Denebola, in Leo, and nearly as far north of
Spica, in Virgo, and forms with these two a large equilateral
triangle. A line drawn from [z] to [[^e]] Ursae Majoris and prolonged
about 30[deg] locates it, as does one from [d] Herculis to [g] Coronae
prolonged its length.

The brightest stars in Bo[:o]tes outline a characteristic kite-shaped
figure. Arcturus is mentioned in the Book of Job and is often referred
to as "The Star of Job."

Three stars of the fourth magnitude are situated in the right hand.
They are about 5[deg] north of [[^e]] Ursae Majoris.

Contrast the color of Arcturus with Spica, Antares, and Vega.

The trapezium [b], [g], [d], and [m], was called "The Female Wolves,"
by the Arabians; [th], [i], [k] and [l], "The Whelps of the Hyenas."
They knew the constellation as "The Vociferator."

Arcturus is the fourth brightest star in the northern hemisphere. It
is 1000 times the size of our sun and rushes through space toward
Virgo at the astounding rate of ninety miles a second. It is forty
light years distant.

The ancient Greeks called this constellation "Lycaon," a name which
signifies a Wolf. The Hebrew name for it was "The Barking Dog."

VIRGO (ver'-g[=o])--THE VIRGIN. (Face West.)

LOCATION.--An imaginary line drawn from Antares in Scorpius through
[a] Librae and prolonged a little over 20[deg] strikes Spica, the brightest
star in Virgo, whi
