A beginner's star-book; an easy guide to the stars and to the astronomical uses of the opera-glass, the field-glass and the telescope . int stars of Cancer,the Crab [50], and directly below Cancer Kes the headof Hydra, the Water-Snake [210], the most extended ofthe constellations. Hydra, like Draco at the north, isnot at first easily distinguished, but, when its stars areonce recognized, it becomes interesting to follow theirclear and winding course. Alphard, the star in Hydramarked Alpha (a) [211], is sometimes called CoRHydr/E or the Serpents Heart. It is a fine objectin a region large but singularly dull. Crater, the Cup[140], is sometimes counted as a part of Hydra, butneither it nor Sextans, the Sextant [375], is brilUantor important. Between Hydra and Orion lies the dim constellation,Monoceros, the Unicorn [270]. Below these faintstars and east of Canis lie the stars of Puppisand , parts of the Ship Argo (Argo Navis) [25].This is a large and brilliant constellation, but too farsouth for us to have more than a peep at it over theedge of the world.

The region of the little star marked Theta (9) inOrion is especially beautiful, for on a clear night—par-ticularly if there be no moon—something may be seenof the great nebula [294]. In Taurus, there are fine objects in the scattered star-cluster called the Hyades [383], near the bright
