Collecting rocks, minerals and those flowers of the mineral world 

 crystals, is a fascinating hobby. The art of collecting and cataloguing can 

 be just as important or just as casual as you want to make it. One can 

 collect "pretty stones" or spend years in building up a collection of quartzes. 

 Also one can exchange with collectors in other countries or confine oneself 

 to acquiring a complete display of the minerals in one's own locality. 



How to Start a Collection 



There are a number of ways to become acquainted with the mineral 

 world. Read books on the subjects. F. B. Lomis's Field Book of Common 

 Rocks and Minerals is a good one to begin with. Join a mineralogical club 

 if there is one in your neighborhood. Ask the science teacher about 

 minerals. Study the exhibits in the museums. Send for the beginner's 

 sample kits and see if you can recognize any of the stones. Join an organiza- 

 tion like the Rocks and Minerals Association.
