It is to be remembered that Polaris is east of the meridian for twelve 
hours before upper cuhnination, and west of the meridian for twelve 
hours after. By setting the instrument at the apparent altitude and 
sweeping near the meridian Polaris can ordinarily be found and the 
instrument placed in the meridian some time before dark. With 
transit instruments not provided with horizontal arc, the value of the 
azimuth adjusting screw may be readily determined and used. 
Without the American Ephemeris these tables ma}^ be conveniently 
used for obtaining the approximate meridian or latitude, in connection 
with Bulletin 14, United States Coast and Geodetic Survey," where 
are given the approximate mean times of culminations of Polaris, and 
the mean declinations for various epochs.
