Capella is visible at some hour of every clear night throughout the year. Of the first-magnitude stars it is nearest to the Pole, and it rises almost exactly in the northeast. To the Arabs Capella was "The Driver," because it seemed to rise earlier than the other stars and so apparently watched over them, or still more practically as "The Singer" who rode before the procession cheering on the camels, which last were represented by the Pleiades. [Illustration: AURIGA] 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°, ends in Præsepe, the Manger, the great star cluster in Cancer, which is also called "The Bee Hive." It contains 300 stars. The stars γ and δ are called the Aselli--the ass's colts feeding from the silver manger. The star β lies about 10° northeast of Procyon. Acubens, α lies on the same line the same distance beyond β. 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 γ, δ, η, and θ, and looks like a nebula to the naked eye. In June, 1895, all the planets except Neptune were in this quarter of the heavens, and Halley's comet was in this constellation on its first appearance in 1531. The dimness of γ and δ is an infallible precursor of rain, and if the Bee Hive is not visible in a clear sky, it is a presage of a violent storm. [Illustration: CANCER] HYDRA (hi´-dra)--THE SEA-SERPENT. (Face South and Southwest.) LOCATION.--The head of Hydra, a striking and beautiful arrangement of stars, lies just below the Bee Hive, in Cancer, 6° south of Acubens in that constellation, and forms a rhomboidal figure of five stars. Hydra is about 100° in length and reaches almost from Canis Minor to Libra. Its stars are all faint except Alphard, or the Hydra's heart, a second-magnitude star remarkable for its lonely situation, southwest of Regulus, in Leo. A line drawn from γ Leonis through Regulus points it out. It is of a rich orange tint. Castor and Pollux, in Gemini, point southeast to it. The constellations Crater, the Cup, and Corvus, the Crow, both stand on the coils of Hydra, south of Denebola, the bright star in the tail of the Lion. Hydra is supposed to be the snake shown on a uranographic stone from the Euphrates, 1200 B.C. The little asterism Sextans, the Sextant, lies in the region between Regulus and Alphard. It contains no stars brighter than the fourth magnitude. [Illustration: HYDRA] LEO (le´o)--THE LION. (Face South.) LOCATION.--A line drawn from Pollux, in Gemini, to γ in Cancer, and prolonged about 12°, strikes Regulus, the brilliant star in the heart of the Lion. Regulus lies about 9° east of Acubens, in Cancer, and about 12° northeast of Alphard, in the heart of Hydra.
