IN THE CORNWALLIS VALLEY. 67 



I was fortunate enough to find that a quantity of sand had 

 been excavated from the south end, and this afforded me an 

 excellent opportunity to examine these deposits. I found 

 the gravel to lie below the sand. They are both fine, and 

 shew good evidence of being deposited in water. I was 

 unable to find any trace of boulder-clay. 



In the first part of this paper I pointed out that boulder- 

 clay was found in this neighborhood by farmers upon digging 

 wells; and I think I can show ample proof that this mound 

 of sand lies above, and, as was suggested by Mr. Wright, is 

 younger than the Glacial Period. 



Following up Mr. Wright's suggestion, I examined a 

 much wider field than this immediate vicinity. At Wolfville 

 and Avonport I have found these stratified sands and gravels 

 to overlie marine clay, and boulder-clay still lower. The 

 scanty literature I find upon this subject supports this view 

 in another part of the valley, namely Middleton. In some 

 places I find the stratified marine clay wanting, but, according 

 to Dawson, all these deposits are not necessarily found in 

 any one place. 



That the eastern part of North America experienced a 

 submergence following the Glacial Period is an established 

 fact, and there is evidence that the Cornwallis and Annapolis 

 Valleys suffered a like fate. Marine clays containing fossils 

 have been found at Avonport and Middleton. Marine 

 benches are seen at different levels on the South Mountain. 

 A wave-cut platform is also reported near Blomidon, and 

 stratified sands and gravels are very common throughout 

 the valley. 



I have searched for fossils in this sand, but without 

 success. 



According to the late Prof. Haycock, this valley was sub- 

 merged by the waters of the Baj^of Fundy after the Glacial 

 Period, and the North Mountain was left as a low island in 

 the Bay. 



In conclusion, I think that the origin of this bank of sand 

 may be found by examining the effects this submergence
