On a right hand page make as large a diagram as possible of 

 the window. Mark the pane to correspond with the position of the 

 sun and neatly add the date.

 gram to showthe position 

 of the sun on the longest 

 and shortest days. 



(3) Select one of the bars 

 of the window sash, and 

 make on the floor a mark 

 corresponding with the posi- 

 tion of its shadow at noon, and put in the date. (See figure 24.) 



Write a description as before and make a plan of the floor of the 

 room on which to show the position of the shadow. 



Note : The shadow may be traced throughout the year in the 

 same way as the apparent " position of the sun on the window." 



Subsequent observations will show how the sun's position changes
