SUPERFICIAL GEOLOGY OF DUNDAS VALLEY. . 119 



in support of it is pretty well decided, is not so easily traced. Of the 

 other two the evidence is not so clear, as only parts of them are to 

 be found. These beaches so far as can be traced are all rudely par- 

 allel to each other, crossing the valley in a circular form and having 

 their convex sides looking north east towards the lake. 



Taking these beaches in serial order, we have first, Burlington 

 Beach, a low sandy and gravelly bar about five miles long, varying 

 from a hundred yards to half a mile in width, and in no part elevated 

 more than a few feet above the level of the lake. 



This, I would assume from its positon and elevation to be the 

 most recent of the series of beaches to be found in the valley. Its 

 elevation corresponds pretty nearly with the lowest beach given by 

 Dr. Chambers, or about 242 feet above sea level. 



Second, Burlington Heights. This is a beach of much older origin 

 than Burlington Beach. It forms the barrier between Burlington 

 Bay and Dundas valley proper. This beach with its broken strata 

 of sand, gravel and conglomerate, begins close to the escarpment on 

 the south of Hamilton, about the end of Catharine street, and can be 

 traced through the city of Hamilton along the road leading to Bur- 

 lington village. It is separated from the raised level country lying 

 along the escarpment at the northern end by a deep channel, at one 

 time the mouth of the old canal and outlet of the waters flowing 

 through the marsh into Burlington Bay. 



A very fine section of this beach can be seen on the line of the 

 G. W. Railway, from Dundurn grounds to where the line passes 

 around it at the old mouth of the canal. 



From levels kindly supplied to me Mr Haskins, the city engineer, 

 I am enabled to give here the heights of this old sea margin at vari- 

 ous points in its course through the city.
