No. 5.] WILKINS EOZOIC ROCKS IN CANADA. 281 



the Shannonville outlier, which it probably antedates, it possesses 

 several veins of white quartz, two of the principal of which run, 

 one in a direction N. 43° E. while the other intersects the down- 

 throw referred to above with a strike N. 62° W. The latter is 

 best seen upon the north-east face of the fault which is vertical, 

 the opposite face being of gradual elevation from the lowest point 

 and the vein being partly concealed by vegetation. Each of the 

 veins is about sixteen to eighteen inches in width. 



On the summit, whence a fine view can be obtained of the 

 plain beneath, are several grooves and scratches and polishing 

 caused by stones imbedded in ice, these being generally S. 67° 

 W., or nearly parallel to the strike of the mountain, and also to 

 the strike of numerous small cracks, while perpendicular to 

 others, which seem to strike S. 62° E. In one place a most 

 interesting groove runs along to the depth of two inches, the 

 vertical face of a small eminence, this groove being continued 

 with a strike S. 63° W. along the horizontal rock when again 

 met with. Wherever a crack or fissure occurs transverse to the 

 striation, it is noticeable that only the north-eastern face of the 

 fissure has been acted on, the southwestern always remaining 

 intact. Boulders of the rock are very rare on its north-eastern 

 side, but are rather common on the south-western edge. At 

 various places on the south east side of the mountain, and at 

 intervals over its surface the Trenton limestoue is readily dis- 

 cernible, dipping S. 33 Q E. < 23° to < 26°, while on its south- 

 western face it dips S. W.< 15°, and in in my places the line of 

 junction between the two formations can be easily made out. 

 On its north-west side occurs a bed of stratified gravel, apparently 

 about ten feet in thickness, extending to the south-west side of 

 the mountain. 



In conclusion, it may be remarked that a hill about half a 

 mile in length trending apparently north-east, rising to the same 

 height as the Shannonville outlier but presenting an escarped 

 appearance, and distant about one mile to the north-west of the 

 latter, is composed, according to Prof. McCoun, who has min- 

 utely examined it, of the thick-bedded limestone, which cropping 

 out on the Bay of Quinte at " Ox Point " about four miles to 

 the East of Belleville, is met with near Stoco (or Stucco) Lake 

 in Hungerford, and overlying the metamorphic rocks of Madoc 

 and Huntingdon on Hog Lake in the latter township. Professor 

 McCoun has also collected from the Shannonville outlier the
