C. OUR NATIVE WILD FLOWERS 



It is well known that in many places where wild flowers used to 

 be abundant they are rapidly becoming rare or extinct. In the 

 case of annuals, this is due to the fact that so many are picked that 

 an insufficient number remain to form seed. In other cases, it is 

 due to the clearing and burning of the woods, the draining of 

 swamps, or the cultivation of the fields. Roadsides also are 

 robbed of all their natural charm by insensate clearing and the 

 automobile makes it possible to go further afield in search of wood- 

 land treasures ! The spring flowers are most in need of protection
