GOD'S GIFT OF SUNLIGHT 307 



an opera glass is constructed, how the lenses are inserted 

 in the tube, the convex lens at the back and the eye-piece 

 at the front. The opera glass is the same form of tele- 

 scope that was used by Galileo. 



The children should be made to realize as much as 

 possible the immensity of space which the telescope has 

 opened up to us; and the knowledge that the prisms have 

 enabled us to obtain of those other vast suns that appear 

 to us as points of light. 



Hand Work 



If possible, have the pupils study light through a prism 

 before attempting to do the work asked for on the leaflet. 



Interest in the Bible passages about the sun may be 

 aroused in class. Remind the children of certain inci- 

 dents and verses they know already which mention the 

 sun: (1) in the story of creation, (2) in the parable of 

 the sower, and (3) in the story of the transfiguration. 

 Do they know where to find these in the Bible, and how 

 to write the abbreviations for the books, and the chapter 

 and verse when found ? A little class teaching and prac- 

 tice on this use of the Bible may be needed. Then the 

 pupils may like to look through a single book, like Psalms 

 or Ecclesiastes or Revelation, to find how many times the 

 sun is there mentioned. 



OPENING TALK 



Shall we repeat together the memory verse for this 

 lesson ? A glory indeed is the bright shining of all these 

 heavenly bodies. Let us name them again (sun, moon, 

 stars). Which is nearest our earth? Which gives us 

 the most heat? The most light? Our story to-day will 

 tell you about God's gift of sunlight.
