GLOW-WORMS, TERMITES, SHELLS 225 



After about ten minutes the snail had clearly given 

 up the struggle. Its efforts slowly died away. In 

 eight minutes more it was quiescent, and the glow- 

 worm withdrew its head, now covered in a dense mass 

 of snail-flesh and slime. It then commenced to clean

 being complete, it again returned to its victim. Slowly 

 it mounted to its previous seat on the shell, and bury-

 not till fourteen hours had elapsed did it cease to feed 

 on the flesh which by then was decomposed and 

 putrid. 



Who would think that these pretty glow-worrns

 minate the world around. But they play a sterner 

 part. They occupy a rough place in life's struggle. 

 They wage a cruel and relentless war. 



I pass now to another of these contests in which life
