12 INTRODUCTION. 



On the whole, the authors flatter themselves, that then' paform- 

 ance will not only prove acceptable to the lovers of science, but 

 interesting unto others. To the manufacturer and the man of busi- 

 ness, it may be of considerable service, to know the valuable mineral 

 products of this part of England. The landed proprietor may derive 

 much profit from an inquiry into the natm'e of the rocks of this district, 

 liarge svims have been thrown, away in boring for coals, and other 

 speculations, which might have been wholly saved to the adventurers, 

 had they been properly acquainted with the strata. Above all, the 

 admirers of the works of God, will here find matter calculated to 

 awaken and cherish the best feelings of the soul, to call forth and 

 keep alive those sentiments of devotion, humility, gratitude, and 

 love, which, while they honour that infinite Being whose works are 

 here examined and described, serve also to exalt our understandings, 

 .and improve our hearts. If the authors shall contribute in any degree 

 to produce such effects, their highest object will be accomplished.
