A TABLE OF ONE HUNDRED AND THIRTEEN BRIGHT STARS. To ascertain when any Star or Constellation found in the following Table will be on the upper meridian, add the numbers opposite in the left-hand column of figures to the time of "Sidereal Noon" found in these pages. For the rising of a Star. subtract the number opposite in the right-hand column of figures from its meridian passage. For the setting of a Star, add the same number to its meridian passage. Those marked (....) revolve in a circle of perpetual apparition, and do not rise or set north of the latitude of New York (40° 42′ 40′′), for which latitude the semidiurnal arcs are calculated. The civil day begins at midnight, and consequently 24 hours after midnight, or 12 hours from noon, is morning of the succeeding day; and more than 24 hours from noon, is evening of the next day. This table is arranged in the order of culmination. Stars having an asterisk (*) in the last column are seen only in Florida and Texas, when passing the meridian. 15 57 4 49 16 20 4 20 17 2 38 6 2 11 5 75 Ursa Majoris (Mizar). 21 Ursa Majoria (Benetnasch) 14 9 7 12 14 30 * a Piscium (El Rischa). y Andromeda (Almaadi) a Arietis Y Ceti o Ceti (Mira) a Ceti (Menkar)..

The azimuths in the annexed table, applied properly to the magnetic bearing of Polaris at the time of its greatest elongation east or west, will give the true variation of the magnetic needle from a true north direction, and will be of great use to all surveyors and engineers. When the elongation is east the azimuth will be east and vice versa. At the present time the line of "No Variation" of the needle runs southeasterly from near Toledo, Ohio, to a point on the Atlantic coast about fifty miles southwest of Cape Fear, N. C. East of that lines the north end of the needle points west of a true north, and west of that line east of the true north. The country may therefore be divided into eastern and western magnetic regions. In the "Eastern Region" the bearing of Polaris at its western elongation, if eastward, added to the lazimuth, gives the desired variation west; but if westward, the bearing taken from the azimuth gives the variation west. The bearing of Polaris at its eastern elongation will be eastward, and the azimuth subtracted therefrom gives the variation west. In the "Western Region" the bearing of Polaris at its eastern elongation, if westward, added to the azimuth, gives the variation east; but if eastward, the bearing taken from the azimuth gives the variation east. The bearing of Polaris at its western elongation will be westward, and diminished by the azimuth gives the variation 'east. The azimuths in the table, given for two degree zones, are practically sufficient for all the United States except Alaska. For intermediate latitudes, and dates, the azimuths may be found by proportion sufficiently correct, or exactly by the formula, log-sine azimuth equal log-sine Polar Distance of Polaris, minus log-cosine latitude. The surveyor or engineer is on the line of "No Variation" when the bearing of Polaris at greatest elongation is the same as the azimuth. Polar Azimuth of Polaris at its Greatest Elongation East or West. 35° 41° tance of " o " " о " " " January.. | 11 13 43 1 24 17 1 26 11 27 54 1 29 59 1 32 19 1 34 511 37 401 40 49 1 44 16 95555 57 17 501 57 57 59 February.
