 turned to account, it would no doubt be brought into use were a 

 demand created for its valuable product. 



It would be out of place to enter into any detailed speculations 

 respecting the eligibility of introducing this substance as a material 

 for candles. It may however in general terms be stated, that it 

 could be imported into this country at less than one-fourth the 

 price of wax, and though it does not possess all the advantages 

 of that substance, it is still considerably superior to animal tallow.

 in its practical, and in its theoretical relations, the first teaching 

 us the relative positions, aspects, and qualities of those mineral 

 aggregates, or rocks, which incrust the solid nucleus of our 

 globe ; and the second aiming at the discovery of the causes by 

 which they have been produced, and investigating the events 

 which have attended their deposition, and influenced their ar- 

 rangements and characters. 



In either view of the subject, geology presents an interesting 

 field of inquiry, and when observation is blended with theory, 

 when we are permitted to relieve the drudgery of collecting facts 

 by incursions into its speculative regions, it opens a train of study 

 and of research, to which few, from its variety and importance, can 

 be inattentive or indifferent. 



Whatever temptations may be held out, to deviate into the 

 contrary path, and to amuse ourselves with the hypothetical 

 flights of the numerous writers who have indulged in the specula-
