I920. Callag AN — Glacial Deposits of Walerville. 83 



At a sharp turn in the road about half a mile farther 

 on, where a small stream comes down a little valley, there 

 are two fine perched blocks, and the rocks by the road 

 side are smoothed and striated strongly. 



Near Glen Moor school, where the road rises abruptly 

 around a curve, the direction vaiies. On the right hand 

 side, the rocks are well smoothed and the markings, which 

 are shallow, vary from 9 to 12 inches in width and firom 

 2 to 3 inches in depth. They are from 20 to 30 feet long 

 and have a very striking effect, the direction being E. by 

 S. and N. by W. This change from the prevailing direction 

 is probably the resultant line of two forces of flow, one from 

 nearly opposite and the other from the upper valley, the 

 sharp rise of the ridge possibly also influencing the direction 

 of the flow. Six hundred yards south of this the striae 

 resume their usual N.E. and S.W. direction. 



At Tarmons, on the N.W. side of the lake, there is a 

 curious bit of land surface, suggesting that when, in the 

 ice-filled Currane Valle}^ the ice-front conformed more or 

 less to a low ridge, the waters from the Cummeragh Valley 

 glacial front ran in a strong stream between the steep 

 hillside of Tarmons and the ice front, carving out the little 

 valley now remaining and running from there down to the 

 lake west of the " Black Rock." The present small stream 

 in the shallow valley is the modern representative of this 

 much larger river. 



The glacial deposits are very extensive and good sections 

 are easy of access. 



This drift is found in all the mountain hollows, the 

 shallow lateral ravines, forms the soil of most of the valleys, 

 composes most of the shores of the ba}^ and covers the 

 various islaads in the lake, the bay, and those in the Ken- 

 mare River. It is composed of very fine sand, clay and 

 gravel, and boulders of all sizes. The sand is frequently 

 found in long wavy masses or layers. It is a remarkable 

 fact that along a certain well defined line of stones, the 

 original deposit seems to have been denuded and another 

 subsequent deposit more horizontally stratified laid down 

 on the washed surface of the older deposit. This last 

 deposit forms the present land surface. A short survey
