THE MINERALOGY AND LITHOLOGY OF NEW HAMPSHIRE. 
INTRODUCTION. 
EW HAMPSHIRE is widely celebrated for its rocks and minerals. 
We read much in literature of its granite hills and its rocky peaks. 
Literary men and artists have, however, generally been satisfied to call 
the material of every mountain cliff, every boulder, the walls of every 
ravine, simply rock or granite; but, if one has stopped occasionally to 
notice the individual appearance of the rocks, and the many and mani- 
fest differences in them; has sometimes noticed in them the mineral 
crystals, often of rare beauty; or has searched among them for sub- 
stances of value,—he will certainly observe that in New Hampshire a 
wonderful diversity of minerals and rocks is found. Here are minerals 
of both economic and scientific interest, and rocks most widely different 
in composition and mode of formation; and it is the object of this report 
so to describe and classify the mineral productions of the state, that 
those who interest themselves in such studies may know and be able to 
identify the minerals and rocks by which they are surrounded. 
Mineralogy and lithology are economic sciences. A knowledge of the 
first enables one to detect the valuable products which can be extracted 
from the crust of the earth: a knowledge of the latter enables one to tell 
the value of rocks for building purposes, and the other uses to which they 
are applied ;—and although the manifest utility of these studies has always 
given them zest, yet it is hoped that many people, in this state so full of 
minerals, will be interested in reading the more purely scientific parts of 
this essay, in which the attempt is made to show, by simple means, the
