I04 BOY SCOUTS OF AMERICA . ANTARES (An-ta'-rez). A deep-red star, the chief one in Scorpio, which is on a line drawn from the front bottom corner of the Dipper, through the end of the handle, three total Dipper- lengths, touches Antares. It can be seen by us only in summer, and is low in the southern sky. '* In the last visible stage of cooling" (Lockyer). *' Almost extinct " (S.). . (ALPHA, of the Southern Cross) cannot be seen in the northern latitudes. . ALTAIR (Al-tair), of the Eagle, a diamond-white star. Draw a line from Mizar to Vega, then one-half as far again, and it touches Altair. . SPICA (Spi'-ka), of Virgo, a diamond-white star. A line drawn from the Pole Star through the first star in the handle of the Dipper, away from the bowl, carried on about two total Dipper-lengths farther, reaches Spica. Or, the Dipper-handle curves on to Arcturus, and carry the same curve on as far again, and it reaches Spica. DENEBOLA (De-neb'-o-la) is in the Lion's tail; with Spica and Arcturus, it marks the corners of a great equilateral triangle, " remarkable for its pure white light; ... no companion star in the sky equal to it in this respect " (vS'.)- It is so far away, we can neither compute its motion nor its distance. . FOMALHAUT (Fo'-mal-o), of the Southern Fish, a star of autumn, seen far down to the south. When the outer edge of the Dipper is straight under the pole, Fomalhaut is due south. The line of the Pointers through the Pole-star, continued across the heavens about three and one-half total Dipper-lengths beyond, touches Fomalhaut. It is a lonely star, no other bright one being near. Is one of the stars important to the mariner (S.). . (BETA, of the Southern Cross) cannot be seen in north- ern latitudes. . REGULUS, of the Lion, a white star. Follow the front and back sides of the Dipper downwards and backwards till they meet, that is, about one and one-half total Dipper-lengths, and they reach Regulus. This star is also in the end of the handle
