 bring- back and exhibit by and by. Some chapters offer

 young friends establish chapters in almost every place 

 they visit, maintaining also during their absence regular 

 correspondence with their companions who are detained 

 at home. In this way the close of the vacation finds in- 

 creased, rather than diminished, interest in nature, and 

 the chapter gains a new impulse and enters upon its 

 work with fresh elasticity and vigor.
