NIGHT SKY.--MAY AND JUNE.

The Great Bear (_Ursa Major_) occupies all the upper sky from the

west to north, except a small space occupied by the Hunting Dogs

(_Canes Venatici_). The Pointers are in the northwest, almost

horizontal. A line from the Pole Star (a of the Little Bear--_Ursa

Minor_) to the Guardians of the Pole (b and g) now occupies the

position of the minute hand of a clock 3 minutes past an hour.

Due north, low down, lies _Cassiopeia_, while above, somewhat toward

the east, we find the inconspicuous constellation _Cepheus_. The

Camelopard is in the west of north, and getting upright.

Low down in the northwest lie the Charioteer (_Auriga_), and the

head stars of the Twins (_Gemini_) further west. The Crab (_Cancer_)

is nearly due west, the Sea Serpent (_Hydra_) holding his head

almost exactly to the west point. Above is the Sickle in the Lion,

its blade curved downward, and the tail of the Lion (_Leo_) lies

above, toward the south of west.

On the Serpent's back we find the Cup (_Crater_) and the Crow

(_Corvus_), in the southwest and to the south of southwest respectively.

Above these constellations, and extending beyond the south toward

the east, the Virgin (_Virgo_) occupies the mid-heavens.

Above the Virgin we see the Herdsman (_Boötes_), his head and shoulders

nearly overhead. Low down in the south is the Centaur (_Centaurus_),

bearing on his spear the Wolf (_Lupus_) as an offering for the

Altar (_Ara_), which, however, is invisible in these latitudes.

Above the Wolf we see the Scales (_Libra_), while the Scorpion

(_Scorpio_), one of the few constellations which can at once be

recognized by its shape, is rising balefully in the southeast.

The Serpent Bearer (_Ophiuchus_) bears the Serpent (_Serpens_) in

the mid-heavens toward the southeast, the Crown (_Corona Borealis_)

being high up in the east, close by the Serpent's head.

Low down in the east is the Eagle (_Aquila_), with the fine steel-blue

star _Altair_, the Swan on the left about northeast, and above

it the Lyre (_Lyra_), with the still more brilliant steel-blue

star _Vega_. Hercules occupies the space between the Lyre on the

one side and the Crown and the Serpent's head on the other. He

is high up, due east.

Lastly, the Dragon winds from between the Pointers and the Pole

round the Little Bear, toward Cepheus, and then eastward toward

the feet of Hercules, close by which we see his head and gleaming

eyes (b and g).
