192 SOME NOVA SCOTIAN ILLUSTRATIONS 
QUARTZ VEIN IN LAMINATED SLATES. 
A singular instance of a very narrow but tortuous vein seen 
upon the shore about Kagle Head Breakwater, east of Liverpoul 
Harbor, is here reproduced. ‘The contortions are in exact corres- 
pondence with the corrugations of the enclosing strata. 
Another type of veins of much interest is where these latter 
consist of granite, and, with other contact phenomena, finds 
abundant illustration at many different points along the borders 
of the principal granitic masses. <A striking example of such a 
granite vein or dyke of large proportions may be seen on the 
shore opposite Coffin’s Island, near the eastern head of Liverpool 
Harbor. The beds exposed here are chiefly gneisses, quartzites, 
and mica schists, of the Cambrian system, and have a very 
regular northward dip of 40°. Across these beds, however, and 
almost at right angles, ran heavy masses of coarse white 
weathering granite, the dip and strike of the strata being 
apparently wholly unaffected thereby. (See Fig.) In the same
