TIMES OF UPPER MERIDIAN PASSAGE OF POLARIS, OR NORTH STAR, 1898.
Surveyors and civil engineers may obtain the variation of the magnetic needle for any place in the United States by directing
their compase to the North Star (Polaris) when it is upon the meridian, as given in the table below, for the upper culmination:
or 11 hours 58 minutes 2 seconds, before or after, when the star is on the lower meridian. Exact local time is used in the table, and the
timepiece used must be correct, and the bearing of the star taken promptly on time, and that bearing will be the true variation of
the needle. An error of only a few seconds in the timepiece will vitiate the bearing found; therefore, it will be much better to
take the bearing when the star is furthest east or west, at its greatest elongation, as observations made upon it then are not affected

materially by small errors of timepieces. To use this table for other places than Washington, D. C., add 9.83 seconds for each hour of longitude east of Washington, and subtract 9.83 seconds for each hour west of it. From February 1 to August 1, use the lower culmination. (For table to find the time of greatest elongation of Polaris, see Page 1, Table I. Almanac of 1897.)

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.
