The Distribution of Insects in New Hampshire. 1 — The author, 

 in this interesting essay, discusses with his characteristic thorough- 

 ness the relations of the fauna? (Alpine, subalpine, Canadian and 

 Alleo-hanian) which have their representatives in that state. It is 

 illustrated by a map of the state, showing the relations of the 

 Canadian and Alleghanian fauna?, and another of the Alpine and 

 subalpine regions of the White Mountains. The data are drawn 

 from the butterflies ami grasshoppers. We were not aware that

 subject, which will, we doubt not, greatly stimulate further studies 

 on the geographical distribution of insects in this country.

 adapted it for the instruction of young miners starting in life. 

 We have not met with a better and briefer introduction to the art 

 of mining for the general reader.
