diate vicinity, and abounds in a great many interme- 

 diate localities, from which materials have been 

 obtained for the canals and other public works. The 

 stone required for the great Victoria Bridge at Mon- 

 treal was in a large part procured from Pointe Claire, 

 a few miles above the city. Limestones and dolomites 

 of superior qualities for building purposes are met 

 within a great many places in the region to the west 

 of Lake Ontario ; which also yields in numerous lo- 

 calities a superior sandstone, of which University 

 College, Toronto, and many other of the public 

 buildings of that city and of Hamilton are con- 

 structed. Good sandstones for building purposes are 

 also met with among other places at several points 

 on the Ottawa, at Sillery near Quebec, and in the 

 more eastern parts of the province. 



In the Eastern Townships, to the east of the Notre- 

 Dame range, there are great quantities of granite of 

 a superior quality for building purposes, and in 

 many parts of the Laurentian region, granite, sye- 

 nite, and syenitic-gneiss rocks abound, both red and 

 gray in colour. Some of these materials are equal to 

 the granites of Cornwall and of Aberdeen, and would 

 yield materials for building and for decoration of 

 great beauty and durability; but as they are both more 

 costly to work than the abundant limestones and 

 sandstones, and generally more remote from the 

 great centres of consumption, they are as yet scar- 

 cely made use of. 



MARBLES. 



The rocks of Canada afford a great variety of mar- 

 bles^ Some of the limestones of the Laurentian 

 region aiford a good white marble for building pur- 

 poses and for tombstones, as at the Calumet, Por- 

 tage du Fort, and Fitzroy Harbour ; from which last
