of a part of the Saguenay Country. 83 
Its prevailing colour in the neighbourhood of Quebec, of 
which it is a characteristic rock, is greenish grey. It possesses 
a mechanical and granular structure, being composed of rounded 
grains of quartz, thickly distributed through a base of indurat- 
ed clay ; these are sometimes large enough to render the term 
pudding stone applicable to it. Small white crystals of felspar 
and small angular pieces of clay-slate are occasionally seen in it. 
It is almost always characterised by a great degree of solidity 
and infriability, and could never be mistaken for one of the latest 
sandstones. The grey wacke of Cape Rouge is an excellent 
building stone, and has been much employed in the scarps of 
the new fortifications at Quebec. Although the predominating 
rock, grey wacke, is comparatively rare among the debris or 
shingle on the shore, owing to its power of resisting the disin- 
tegrating action of the atmosphere ; while clay-slate, for a con- 
trary reason, covers the shore in angular fragments. 
These two rocks continue without interruption, as far to the 
westward as the Telegraph, from the neighbourhood of which 
Messrs. Nixon and Bowen brought specimens of the latter, 
much discoloured by the red oxide of iron, and containing small 
rounded nuclei or nests of magnetic iron, These gentlemen 
report the soil over which they passed, to be sandy and much 
neglected, a description that will apply to most of that we saw 
on this island. A few yards beyond high water mark, the 
rocks suddenly emerge, and form a bank about fifty feet high, 
running parallel to the river. Having walked about a mile to 
the eastward of Patrick’s Hole, along the shore, no important 
geological change was observed. 
At river La Fleur, off which adverse winds obliged us to 
anchor, the same rocks were observed; we here learnt, how- 
ever, that limestone is found in the adjoining parishes of St. 
Frangois, to the eastward, and St. Laurent to the westward, 
atthe latter of which places lime is burnt for the supply of 
the
