368 LIGHT. 



A. As these animals cannot see 

 distinctly in strong daylight, they sleep 

 during the day : and as they can see 

 clearly in the dark, they prowl then for 

 prey. 



Q. Why do GLOW-WORMS glisten by NIGHT 

 only? 



A. Because the light of day is so 

 much stronger, that it eclipses the feeble 

 light of a glow-worm ; in consequence of 

 which, glow-worms are invisible by day. 



Q. Why can we not see the STAES in the 



DAY-TIME ? 



A. Because the light of day is so 

 powerful, that it eclipses the feeble light 

 of the stars : in consequence of which, 

 they are invisible by day. 



Q. Why can we see the STARS even at MID-DAY, 

 from the bottom of a deep WELL ? 



A. As the rays of the sun never come 

 directly over a well, but the rays of the 

 stars do ; therefore the light from those 

 stars (in such a situation) is more clear 

 than the light of the sun. 



Q. What is the USE of TWO EYES, since they 

 present only one image of any object ?
