On the first of the month, at eight o'clock in the evening, the zodiacal constellations above the horizon, in their order from east to southwest, will be as follows : Taurus, Aries, Pisces, Aquarius, Cap-ricornus, and Sagittarius. As we face eastward, the brilliant and extensive group formed by the Pleiades, the Hyades and Aries at once attracts the eye; above Aries, and just east of the zenith, lies the great " square " of Pegasus.

The northeast is brightened by Cassiopea, Perseus and Auriga, the latter led by its lucida, Ca-pella, second only of all the stars then above the horizon to Vega, which in turn yields the palm of brightness only to the great Sirius himself.

The Polestar holds the "empty places " of the north almost alone, accompanied only by the Guards, and watched from the northern horizon by the Greater Bear. From the zenith downward to the northwestern horizon stream in brilliant array the Swan, the Lyre, Hercules, the Crown, gemmed with the bright stars Deneb, Vega, Ras Algethi, and Gemma.

South of this brilliant line, and due west from the zenith, lies Aquila, with its bright leader, Al-tair, and the small but old and well-known aster-isms, Delphinus and Sagitta.

Below the zodiac is a dim-appearing region of small stars, relieved only by the great group of Cetus in the east, the lonely bright star Fomalhaut in the south, and the Galaxy region of Scutum in the southwest.

Four hours later, at midnight, the scene has changed; Hercules, the Crown, Aquila, Scutum, Capricornus and Sagittarius have set; Vega and Fomalhaut are trembling on the horizon in the northwest and southwest; but from due east to southwest stretches the northern stream of the Galaxy, studded and flanked by its retinue of blazing constellations, all the great ones of the northern heavens, from the Greater Dog in the east to the Swan in the northwest.

Canis Major, Canis Minor, Orion, Gemini, Taurus, Auriga, Aries, Perseus, Cassiopea, Andromeda, Pegasus, Cygnus, Lyra, all the greatest constellations of the north, are all in evidence at once.

And what an array of first-magnitude stars! Sirius, Procyon, Rigel, Betelgeuse, Aldebaran, Ca-pella, Alpherat, Deneb, Vega; at the eastern end of the sparkling line the brightest, and at the western the second in brightness in the whole heavens.

All these constellations are rich in objects for moderate telescopes: in Canis Major, Sirius, by far the brightest star in the whole heavens, is also a star with a history; its possible change from a red star, as described by the ancients, to its present intense whiteness, its observed irregularities of proper motion, from which Bessel inferred the presence of the satellite actually discovered in 1862 by Clark, in the very flace called for by theory, the strong suspicion amounting almost to certainty, that this companion shines by reflected light, - all combine to make it a most interesting star. The companion, however, is beyond the reach of modest equipments.

Four degrees south from Sirius is the fine cluster 41 Messier, visible to the naked eye, and a fine object in the telescope.

Orion, "the finest constellation in the heavens," is full of brilliant fields and interesting objects, of which we will only specify the brilliant star Rigel, and the great Nebula, which is conspicuous to the eye south of the three stars of the belt, and a glorious show in the telescope.

Taurus has the magnificent cluster of the Pleiades, unsurpassed in the heavens, and, near the star Zeta, at the tip of the northern horn, the wonderful "Crab" nebula, an oval cloud like a small comet in ordinary glasses.

In Auriga the brilliant star Capella, the third brightest to be seen in these latitudes, and the fine clusters 37 and 38 Messier are worthy of attention.

In Perseus is the famous variable star Algol, probably the first star which was noticed to vary in brightness; the splendid "Sword-handle" cluster in this constellation is a naked-eye object, and is a most glorious sight in even a small telescope; the cluster 34 Messier is also a fine low-power object.

In Andromeda, the well-known great nebula, 31 Messier, is visible to the naked eye, and has more than once been mistaken for a comet; the double (really triple) star Gamma Andromedae is a beautiful colored object. There are many fine clusters and brilliant low-power fields in Cassiopea.

In Cepheusis, Herschel's celebrated "Garnet star," so called by him on account of its deep red color; it is the only one of these strongly colored stars visible to the naked eye. The remarkable variable star, U Cephei, is in this constellation.

Cygnus, the great Northern Cross, is full of beautiful views; in fact, all along its middle line of stars you can hardly point a telescope and not find a brilliant field; of its many double stars we will only refer to Beta and Omicron 2 Cygni, both fine in color; there are many telescopic red and variable stars in this constellation.

All the above objects are readily found with the help of a good star-atlas, and all are within the scope of a good 3" glass.
