PREFACE. This volume of the American Nautical Almanac was prepared under the immediate supervision of Professor W. S. Eichelberger, U. S. N., the Director, and follows the arrangement of the immediately preceding volumes. The declination of the Sun, the equation of time, the right ascension and declination of the Moon, and its parallax and semi- diameter are given for each even hour throughout the year; the right ascension, declination, and time of transit of Venus, Mars, Jupiter, and Saturn are given for every day of the year. The apparent places of 55 stars and their times of transit at Greenwich are given for the first of each month and the mean places of 110 additional stars follow. There are also given the elements and circumstances of the eclipses and charts of the solar eclipses; a concise statement of predictions of celestial phenomena; a table for finding the latitude by an observed altitude of Polaris; tables for the conversion of sidereal into solar time and vice versa; a table to enable one to obtain from the Almanac for 1920 an approximate solar ephemeris for subsequent years; and tables for finding the times of rising and setting of the Sun and Moon.
