Abstract
THIS little manual not only provides an easy means of becoming familiar with the chief constellations and individual stars, but also shows how this knowledge may be made practically useful in the determination of position and direction during night marches. The book contains several useful tables giving among other details the time of year when certain stars transit at midnight, the highest altitudes of stars in various latitudes, and pairs of bright stars which transit at the same time. These simul-transit pairs, when vertical, mark the meridian, and also serve as pointers to a celestial pole. The new issue of the book includes some additional notes on the use of the stars as direction and time finders; and it should be found particularly helpful to soldiers and scouts at the present time.
