The constellation Scorpio, of which Antares is the leader, is one of the best marked in the sky. The two small stars Sigma (σ) and Tau (τ), standing like attendants on either side of Antares, lend a singular aspect to the central part of the constellation. Antares is usually represented as the heart of the imaginary scorpion. Below Tau a curving row of stars dips to the southern horizon, and then rises, farther eastward, terminating with a conspicuous pair in the uplifted sting. West of Antares a nearly vertical row represents the head. Of the stars in this row, Beta (β) is interesting as a fine and easily seen double, the distance being about 13″. A higher magnifying power shows that the larger star has another faint companion, distant only 0″.7. Nu (ν) is also telescopically interesting, for it consists of two pairs of stars. Observe in Chart VII the strange way in which the outlines of the constellation have been swung into loops in order to include certain stars in Scorpio, recalling the crooked boundary between Switzerland and Italy, by which each reserves particular peaks of the Alps for itself. East of Scorpio, where the Milky Way, falling in flakes and sheets of silvery splendor upon the southeastern horizon, spreads abroad like an overflowing river, lies Sagittarius, the “Archer,” often represented in the old pictorial charts as a centaur. The stars Lambda (λ), Delta (δ), and Epsilon (ε) form the bent bow. But modern eyes recognize more easily a dipper, formed by the stars Zeta (ζ), Tau (τ), Sigma (σ), Phi (φ), Lambda (λ), and Mu (μ). But the star-clusters in Sagittarius are more interesting than the separate stars. A little southwest of Mu is the famous cluster 8 M., of which Barnard has made a photograph that is amazing beyond all description. Other clusters are all about in this part of the sky. A good opera-glass or field-glass is almost indispensable for one who would enjoy the glory of this wondrous region. Its riches are almost oppressive in their lavish abundance. Here one can have handfuls of stars for the picking up, like sands of gold from the bed of Pactolus. As the glittering incrustations that cover the roofs and walls of the Mammoth Cave are often compared to the starry heavens, so, reversing the image, Sagittarius is like a stupendous cavern of space all ablaze and aglitter with millions of sparkling gems.
