The two neighboring clusters, 46 M and 38^8, are very interesting
objects. To see them well, use a powerful field-glass. A "fiery
fifth-magnitude star," as Webb calls it, can be seen in the field at the
same time. The presence of the Milky-Way is manifest by the sprinkling
of stars all about this region. In fact, the attentive observer will
before this have noticed that the majority of the most brilliant
constellations lie either in the Milky-Way or along its borders.
Cassiopeia, as we saw, sits athwart the galaxy whose silvery current
winds in and out among the stars of her "chair"; Perseus is aglow with
its sheen as it wraps him about like a mantle of stars; Taurus has the
tips of his horns dipped in the great stream; it flows between the
shining feet of Gemini and the head and shoulders of Orion as between
starry banks; the peerless Sirius hangs like a gem pendent from the
celestial girdle. In the southern hemisphere we should find the
beautiful constellation of the ship Argo, containing Canopus, sailing
along the Milky-Way, blown by the breath of old romance on an endless
voyage; the Southern Cross glitters in the very center of the galaxy;
and the bright stars of the Centaur might be likened to the heads of
golden nails pinning this wondrous scarf, woven of the beams of millions
of tiny stars, against the dome of the sky. Passing back into the
northern hemisphere we find Scorpio, Sagittarius, Aquila, the Dolphin,
Cygnus, and resplendent Lyra, all strung along the course of the
Milky-Way.
Turning now to the constellation Monoceros, we shall find a few objects
worthy of attention. This constellation is of comparatively modern
origin, having been formed by Bartschius, whose chief title to
distinction is that he married the daughter of John Kepler. The region
around the stars 8, 13, and 17 will be found particularly rich, and the
cluster 2^7 shows well with a strong glass. Look also at the cluster 50
M, and compare its appearance with that of the clusters in Argo.
