thin, of a very gummy brown silk, and as soon as 

 the cocoon is finished the caterpillar is changed to 

 a chrysalis and thus it sleeps all winter, coming 

 out about June or July the next summer to mate, 

 lay eggs and hatch out a new crop of poison cater- 

 pillars, tiny little fellows with black heads and tan- 

 colored bodies who march along like soldiers fol- 

 lowing a leader to get their rations and march back- 

 again when they are through. They keep up this
