GEMINI (jem'-i-ni)—THE TWINS. (Face West.)

LOCATION.-A line drawn from (B) to (×) Ursa Majoris and prolonged an equal distance ends near Castor, in Gemini. Gemini is characterized by two nearly parallel rows of stars. The northern row if extended would reach Taurus, the southern one Orion. Note the fine cluster 35. M. Herschel discovered Uranus in 1781 a short distance southwest of it. Two wonderful streams of little stars run parallel northwest on each side of the cluster. The cross indicates the spot where the sun appears to be when it is farthest north of the equator, June 21st. Castor is a fine double for a telescope, and Pollux has three little attendant stars. An isosceles triangle is formed by Castor. Aldebaran in Taurus, and Capella in Auriga. There is a record of an occultation in Gemini noted about the middle of the fourth century B.C.

AURIGA (â-ri'-ga)-THE CHARIOTEER.

(Face Northwest.)

LOCATION.-A line drawn from (8) to (a) Ursa Majoris, and prolonged about 45 degrees, ends near the bright Capella, in Auriga, a star of the first magnitude, and one of the most brilliant in the heavens. It is unmistakable, having no rival in brightness near it. Auriga is a beautiful and conspicuous constellation. It is characterized by a clearly defined pentagon. Note the three fourth-magnitude stars near Capella known as "The Kids.” The star (B) is common to Auriga and Taurus, being the former's right foot and the latter's northern horn. The field within the pentagon is particularly rich in clusters. Capella forms a rude square with Polaris, (ɛ) Cassiopeiæ, and (») Ursæ Majoris, and forms an equilateral triangle with Betelgeuze in Orion, and the Pleiades in Taurus.

A line from (0) to (c) Auriga prolonged about 20° ends near (a) Persei.

The solstitial colure passes 2 degrees east of (ß).

Capella is visible at some hour of every clear night throughout the year.

CANCER (kan'-ser)—THE CRAB. (Face West.)

LOCATION-Cancer lies between Gemini and Leo. A line drawn from Nath in Auriga to Pollux in Gemini, and prolonged about 15 degrees, ends in Præsepe, the Manger, the great star cluster in Cancer, which is also called the Bee Hive. It contains thirty-six stars. The stars (y) and (8) are called the Asellithe ass's colts feeding from the silver manger.

The star () lies about 10 degrees northeast of Procyon. Acubens (a) lies on the same line the same distance beyond (ß). These two stars form the tips of the. inverted "Y" which distinguishes Cancer.

An imaginary line from Capella through Pollux will point out Acubens. Close to it are two faint stars. The Bee Hive lies within an irregular square formed by Y, 8, 7, and 0., and looks like a nebula to the naked eye. (8) is situated in the line of the ecliptic.

Halley's Comet first appeared here in 1531.
