The first of March the region overhead is occupied by the very faint
constellation Lynx. South of it, and astride the ecliptic, appear the
constellations Gemini, the Twins, and Cancer, the Crab. These, like
Taurus, belong to the zodiac. The Twins are westward from Cancer, and
are marked by two nearly equal stars, about five degrees apart. The more
westerly and northerly one is Castor and the other is Pollux. Cancer is
marked by a small cluster of faint stars called Præsepe, the Manger
(also sometimes the Beehive). Directly south of the Twins, is the bright
lone star Procyon, in the constellation Canis Minor, the Little Dog.
Sirius and the other stars of Canis Major, which make a striking figure,
are seen south-west of Procyon.
The first of April the zodiac constellation Leo is near the meridian,
recognisable by a sickle-shaped figure marking the head and breast of
the imaginary Lion. The bright star at the end of the handle of the
sickle is Regulus. Above Leo, between it and the Great Dipper, appears a
group of stars belonging to the small constellation Leo Minor, the
Little Lion. Farther south is a winding ribbon of stars indicating the
constellation Hydra, the Water Serpent. Its chief star, Alphard, of a
slightly reddish tint, is seen west of the meridian and a few degrees
south of the equator.
At the beginning of May, when the Great Dipper is nearly overhead, the
small constellation Canes Venatici, the Hunting Dogs, is seen directly
under the handle of the Dipper, and south of that a cobwebby spot,
consisting of minute stars, indicates the position of the constellation
Coma Berenices, Berenice's Hair. Still farther south, where the ecliptic
and the equator cross, at the autumnal equinox, is the large
constellation Virgo, the Virgin, also one of the zodiacal band. Its
chief star Spica, a pure white gem, is seen some 20° east of the
meridian. Below and westward from Virgo, and south of the equator, are
the constellations Crater, the Cup, and Corvus, the Crow. The stars of
Hydra continue to run eastward below these constellations. The
westernmost, Crater, consists of small stars forming a rude semicircle
open toward the east, while Corvus, which possesses brighter stars, has
the form of a quadrilateral.
The first of June the great golden star Arcturus, whose position may be
found by running the eye along the curve of the handle of the Great
Dipper, and continuing onward a distance equal to the whole length of
the Dipper, is seen approaching the meridian from the east and high
overhead. This superb star is the leader of the constellation Boötes,
the Bear-Driver. Spica in Virgo is now a little west of the meridian.
