5. Determine roug-hly the right ascension and declination of the 

 stars : Arcturus, Aldebaran, Sirius, Rigel, Atair, Antares, Capella, Vega, 

 Castor, Procyon. To what constellation does each belong? 



6. What constellations lie in the Milky Way? In the Hcliplic? 

 What constellations are always above the horizon, and therefore visible 

 at night? 



7. Determine the real direction the moon travels in the sky witVi 

 regard to the earth. How many degrees does it travel *in 24 hours? 

 How many in 28 days? 



8. Locate the planets whenever they become visible and follow their 

 •courses. What is an evening star? 



(Procure Whittaker's Planisphere, and Phillip's Orrery, and Whil- 

 taker's Almanac, and study carefully the movements of constellations and 

 Planets). 



LXX. Weather and Weather Observations.. 



Requisites : Daily weather map issued from Meteorological Observa- 

 tory, Toronto, thermometer, barometer, wind-gauge, and, if possible, the 

 maximum and minimum thermometer and hygrometer. 



1. Study the daily weather-map and understand the construction of 

 isotherms and isobars. The meaning of a number of concentric isobars. 



2. Point out clearly low pressure and high pressure areas and their 

 significance. 



3. By a study of several consecutive weather-maps ascertain if the 

 lew pressure area moves. What direction? Why? How far each day? 

 D >es it follow a certain route? 



4. Does a high pressure area move? In what direction? Why? 



•5. Examine several maps and determine the direction and velocity 

 of I he wind near a low pressure area; near a high pressure area. Can 

 you make a general rule? 



ti. What effect will the direction have on the temperature of the area? 

 Exp'ain. 



Discover if the direction of the wind determines locality of cloudi- 

 ness and rain. Explain. 



7. Make dailv observations of the readings of the instruments, and 

 make a record of' such observations in a special note-book. 



A schedule such as the following is recommended :
