A CHART OF THE HEAVENS AS THEY WILL APPEAR TO RESIDENTS OF THE UNITED 



STATES AND SOUTHERN CANADA AUGUST 15 AT 10 P. M., AUGUST 22 AT 9.3O 



J'. M., AUGUST 29 AT 9 P. M., AND SEPTEMBER 5 AT 8.3O P. M. 



The lines on this chart corresponding" to meridians are separated from each other by the 

 distance the stars appear to move across the sky in one hour. The lines corresponding to 

 parallels show the direction of the stars' paths from the time they rise to the time they set. 



By remembering that the stars within the space bounded by two meridian lines sink into 

 the western horizon every hour, and that a corresponding stretch of new sky arises out of 

 the eastern sky in the same time, the major portion of the chart will be usable hours after 

 the time named. This, of course, does not apply to stars near the North Pole, like the Great 

 Dipper. They never set — the daylight merely puts them to sleep. 



Do y<>\\ belong to that innumerable throng who have never made personal friends of the 

 stars? If so, you arc missing one of the easiest and most delightful diversions of evenings 

 m the open. The first formality is to meet the Great Dipper, which might be called the 

 supreme announcer. Its pointers, Merak and Dubuhue, will then escort you over to Polaris, 

 king of celestial directions. All the roads of heaven lead to his throne and all the highways 

 of earth are oriented with reference to his position (see pages 173-179).
