"A List of Stars for Navigators for the year 1908" is the title of a small pamphlet from the Nautical Almanac office at Washington, giving lists, of white stars and planets for each month of the year. The American ephemeris gives the ap- parent places for every ten days of nearly 400 stars. Only about forty of. the brighter ones, however, are available to navigators. By making a list limited ap- proximately to stars which may be observ- ed with the.sextant when. the horizon is visible in twilight or mooiilight, selection' and identification are made more con- venient. Various tables are given with instructions for their use. A chart is at- tached which is intended to aid in the identification of the stars on the monthly list. This star pamphlet for 1908 will be supplied by the superintendent of docu- ments at Washington upon receipt of 10 cents by postal money order, express order. or New York draft. Postage stamps, foreign money, uncertified checks, defaced or slick coin, will not be accepted. ins, connecting quadrant with regular steering éngine situated, at some point. distant, h: thas gear teeth meshed in" pinion' ©.
