A beginner's star-book; an easy guide to the stars and to the astronomical uses of the opera-glass, the field-glass and the telescope . t it will also containthe position of the moon and planets by Right Ascension and Declination for each day; the predictions of all occulta-tions by the moon for the year, see p. 78; the eclipses of the year; and the phenomena of the satellites of Jupiter andSaturn. In Canada, the same data are to be found in the Annual of the Canadian branch of the Royal AstronomicalSociety; in Great Britain in the Nautical Almanac as well as in such publications as Whitakers Almanac and theCompanion to the Observatory. Clear and simple tables showing the hours of rising and setting of the planets, thephases of Venus, and much other useful information may be had, in the United States, in such annual almanacs asthose published by the iVeTO For^ Tribune and the Brooklyn Eagle. The Tribune Almanac is published, 25c., at theopening of each year. An even simpler volume, lOC, is the Old Farmers Almanack, published by WiUiarn Ware &Co., Boston, Mass. For its weather predictions Iwould not be JUPITER, 1910 Photographed al the Lowell Observatory, Flagstaff,.Arizona ^bc Iplancts 83 \/ tions in which the planets occur. Then find the evening sky for the date in question byreference to p. 35. For example, if our approximate time be the early evening of March,1912, we find from the Tables here that Mars is in Taurus, Saturn in Aries, Jupiter inScorpio, and Venus near the boundary between Capricomus and Aquarius. The TimeSchedule of the stars, p. 35, refers us topp. 43, 45, for the skies of the early even-ing in March. As Scorpio, Capricornus,and Aquarius are not in the skies shown,we know that Jupiter and Venus are notvisible. As Taurus and Aries are shown,well over to the west in our Key-Map ofthe sky, see p. 45, we know that Saturn andMars are visible and are there before the field covered by our map is rich inbrilliant stars, a little care
