Butterfly Collections 



There are few groups in Nature which offer such ad- 

 vantages to the collector as that of the butterflies. They

 of value to the sum of human knowledge. 



The mistake most commonly made by beginners with 

 butterflies, as with other coUections, is to undertake too

 a collection of the butterflies of the world, it is much better

 simple matter to reach out and make a collection of the 

 butterflies of the state or even of the particular region in 

 which the state is located. The natural limitations for a 

 collection in New England is to make a collection of New

 interest and satisfaction to the pursuit. 



The main value of any collection of objects lies in the
