386 NATURE-STUDY REVIEW [14:9— Dec, 1918 



2. Does the Chair move around the Pole Star as does the Big 

 Dipper? Why did the ancients name this constellation Cas- 

 siopeia's Chair? 



After this the Little Dipper may be shown in the same way. 

 The diagram is so long and wandering of the constellation, called 

 The Dragon, that it is rather difficult to teach it in this manner. 

 However, since the two stars in the Dragon's tail lie near to the 

 bowl of the Big Dipper and the Pole Star, perhaps the pupils 

 may be able to work it out partially. However, it is not an 

 especially important constellation. 



The next lesson may be given on Orion. 



m B The diagram III should be placed upon the 



board and proceed as before; the location 



of the constellation should be described, 



and the following observations should be 



called for : 



^JL ■& 1 . How many stars in Orion's belt ? How 



"^ many in his sword? What is the color of 



y the bright star above the belt ? What is the 



^ name of this star? What is the color of the 



* bright star at about equal distance below 



■fy the belt ? What is its name ? 



^JT 2. Read the story of the myths of Orion, 



Diagram III the great hunter, and write an account of it. 



O r ion After these studies have been made, the 



b— Beteiguese following questions should be asked : 



m— Beit 1. Does the Big Dipper and Cassiopeia's 



5 — Sword , 



Chair ever set? 



2 . Does Orion rise and set ? 



3. Why do not the Big Dipper and the Chair rise and set like 

 Orion? 



4 . If you should stand at the North Pole where would the Pole 

 Star appear in the skies? 



5. If you were at the North Pol j would any star seem to rise 

 and set? 



From this lesson the pupils should reason out for themselves 

 the following facts. It is very important for us to know the Pole 

 Star because the northern end of the earth's axis points toward it 

 and it is, therefore, situated in the heavens almost directly above 

 our North Pole. For those of us who live in the Northern Hemis-
