the gland already mentioned 

 binds all the eggs in a single 

 hole into one mass, and 

 when the number is com- 

 pleted more fluid is poured 

 out, which hardens into a 

 firm covering. Here they 

 remain over the winter and 

 hatch out into young grass- 

 hoppers in the spring, quite

 except in absolute and rela-
