turns the same side to the sun, and therefore there is no 

 succession of days and nights. 



To see Venus in the daytime. In order to see Venus 

 while the sun is above the horizon you must be in the 

 shade and must know just where to look. Proceed as 

 follows : 



(1) When Venus is an evening star, note the time of 

 setting of the sun and the time of setting of Venus. Note 

 whether Venus sets north or south of the place where the 

 sun sets. 



(2) As the majority of roads and streets have been 

 laid out either north and south or east and west, the 

 majority of buildings have walls running in these direc- 

 tions. A wall that runs north and south is in the plane 

 of the meridian. At twelve o'clock, sun time, stand 

 at the northeast corner of a large building where its 

 shadow will touch you. Notice carefully on the build- 

 ing the direction of the sun just before it is hidden from 

 your view. After a while Venus will be in this same di- 

 rection from you if you are then in the same place as at 

 twelve o'clock. The planet will be on the meridian about 

 the same number of minutes later than the sun as it 

 was later than the sun in setting ; it will be somewhat 

 higher in the sky, if it sets north of the sun; lower, if 

 it sets south of the sun. j 



When Venus is a morning star rising 2 hours and 20 

 minutes before the sun, at which corner of the building 

 should you stand in order to see the planet in the 

 daytime ? When would it be on the meridian ?
