COAL. 37 



Again.— The prevalence of sulphur and salt in 

 the shape of springs, and of gypsum in the form of 

 quarries, demonstrate the existence of coal. They 

 are invariably companions. Providence dispen- 

 ses its bounties in a remarkable manner. These 

 invaluable fossils, coal, salt and gypsum, are 

 always found in the same region. The great 

 ranges of hills in Canasaraga, Onondaga, Ontario, 

 and Genessee, are ramifications of the Alleghany 

 mountains, the seat of coal in Pittsburgh. 



One of the richest salt mines in England, was 

 discovered by digging a canal. The western 

 canal in its windings round hills, in the deep cut- 

 tings which it produces, and the extensive explo- 

 rings and examinations which it occasions, will 

 undoubtedly bring to light great mines of coal, 

 more valuable than the precious metals of Peru, 

 and the precious stones of Golconda. The places 

 to look for this important mineral, are deep ra- 

 vines, formed by floods ; the vallies at the foot of 

 high hills, and vertical sections produced by the 

 overflowings and abrasures of streams. 



Thin lamina? of coal have been seen in various 



places — and the Indians say that they have found 



n re-stone in the woods. The moment coal i 



discovered within fifty miles of the canal, what 



sources of wealth will immediately be developed.
