THE GEOLOGIST. 



the supposition, that the rocks forming each lofty peak, 

 were produced by similar causes throughout. 



To use the words of our author, " the rocks constituting 

 this range of high lands, are such as are believed by almost 

 every Geologist, to be of volcanic origin ; a doubt on this 

 subject cannot remain in the mind of the unprejudiced after 

 their characters are fully examined, and the general appear- 

 ance of the country where they are situated, is compared 

 with the theatre of volcanoes still in operation. 



In the first report our author traces an extensive granitic 

 range from the Chiputnecticook river, to the river St. John, 

 opposite the entrance of Belle-isle Bay. It becomes nar- 

 rower as it proceeds eastward, and at the latter place the 

 true granite disappears ; it is met by an extensive tract of 

 syenite in Charlotte county, and the two become associated 

 in a most irregular manner, passing into each other by inti- 

 mate relations and proving the identity of the forces ex- 

 cited to produce their eruption. 



The syenite proceeds onwards in an easterly direction ; 

 forming a remarkable belt across the peninsula of Kingston, 

 between the Belle-isle and Kennebeckasis rivers ; it then 

 forms the tract of country in the neighbourhood of Loch- 

 Lomond, until it reaches Shepody mountain where it termi- 

 nates and is met by rocks of a sedimentary character, its 

 average breadth in this part being about twelve miles, and 

 often it approaches near the coast. 



The limestone has been shown to extend from the en- 

 trance of the St.-John, eastward, to Hammond river, meet- 

 ing the syenite, and are there lost. The slate, greywacke, 

 and greywacke slate occupy a considerable portion of the 

 county of Charlotte, and crossing the river St.-John, re- 

 appearing to the east of the Harbour, and terminates in an 

 easterly direction near Loch-Lomond. They reach north- 

 ward to the Kennebeckasis and southward to Emerson's
