The first of July, when the centre of Draco is on the meridian north of
the zenith, the exquisite circlet of stars called Corona Borealis, the
Northern Crown, is nearly overhead. A short distance north-east of it
appears a double-quadrilateral figure, marking out the constellation
Hercules, while directly south of the Crown a crooked line of stars
trending eastward indicates the constellation Serpens, the Serpent.
South-west of Serpens, two widely separated but nearly equal stars of
the second magnitude distinguish the zodiacal constellation Libra, the
Balance; while lower down toward the south-east appears the brilliant
red star Antares, in the constellation Scorpio, likewise belonging to
the zodiac.
On the first of August the head of Draco is on the meridian near the
zenith, and south of it is seen Hercules, toward the west, and the
exceedingly brilliant star Vega, in the constellation Lyra, the Lyre,
toward the east. Vega, or Alpha Lyræ, has few rivals for beauty. Its
light has a decided bluish-white tone, which is greatly accentuated when
it is viewed with a telescope. South of Hercules two or three rows of
rather large, widely separated stars mark the constellation Ophiuchus,
the Serpent-Bearer. This extends across the equator. Below it, in a rich
part of the Milky Way, is Scorpio, whose winding line, beginning with
Antares west of the meridian, terminates a considerable distance east of
the meridian in a pair of stars representing the uplifted sting of the
imaginary monster.
The first of September the Milky Way runs directly overhead, and in the
midst of it shines the large and striking figure called the Northern
Cross, in the constellation Cygnus, the Swan. The bright star at the
head of the Cross is named Denib. Below the Cross and in the eastern
edge of the Milky Way is the constellation Aquila, the Eagle, marked by
a bright star, Altair, with a smaller one on each side and not far away.
Low in the south, a little west of the meridian and partly immersed in
the brightest portion of the Milky Way, is the zodiacal constellation
Sagittarius, the Archer. It is distinguished by a group of stars several
of which form the figure of the upturned bowl of a dipper, sometimes
called the Milk Dipper. East of Cygnus and Aquila a diamond-shaped
figure marks the small constellation Delphinus, the Dolphin.
At the opening of October, when Denib is near the meridian, the sky
directly in the south is not very brilliant. Low down, south of the
equator, is seen the zodiacal constellation Capricornus, the Goat, with
a noticeable pair of stars in the head of the imaginary animal.
