72 Geology of Massachusetts. 



part of the country. Other states possess particular minerals which 

 are more valuable and interesting, and calculated to awaken public 

 attention more than ours ; yet where is the territory abounding in a 

 greater number of rocks and minerals, of real and permanant utility, 

 whose quality is excellent and whose quantity is inexhaustible ? They 

 are, indeed, of such a character, that they will increase in value for 

 several generations to come. That is, we may calculate that the de- 

 mand for them will increase during that period, and this demand will 

 lead to the discovery of varieties really more valuable. 



Thus far we have regarded our geology only in an economical 

 point of view. I hope to show in the subsequent parts of my Report, 

 that it is not less interesting to the man of taste and science.
