132 SUPERFICIAL GEOLOGY OF DUNDAS VALLEY. 



The records of the well borings which I have been able to 

 obtain, show the state of affairs further down. 



A well on the brick field of Mr. Henry New, gives a section of 

 50 feet : 



Brick clay 8 feet. 



Blue clay, filled with limestone fragments. 6 feet. 



Gravel and sand 32 feet. 



Quicksand, or silt 4 feet. 



Total 50 feet. 



At Bamberger's there are two wells, each twenty feet deepj 

 passing through clay and ending in sand. 



Mr. J. Buttram's well is 38 feet deep and gives a section of : 



Clay 27 feet. 



Gravel 6 feet. 



Hardpan, (conglomerate) .... 3 inches. 



Beach shingle 5 feet. 



Total 38 feet, 3 inches. 



These wells are on a general elevation of about 80 feet above 

 the lake. Farther up the valley, and within a hundred and fifty 

 yards of the Hamilton escarpment, a well dug by Mr. Hamilton 

 Arthur passed through 27 feet of gravel before reaching the blue 

 clay. This well is on the edge of a stream filled with pieces of lime- 

 stone and cannot be much more than eighty feet above the lake. 

 Toward the head of the valley, and in the narrow part of the gorge^ 

 three well-borings have been obtained. 



The first, on Lot 40, of the first concession of Ancaster, has 

 already been referred to, as being 232 feet above lake level. The 

 surface is clay loam, with a sub-soil of blue clay containing boulders 

 and fragments of limestone. This well is 30 feet deep and ends at 

 the sand-rock of the Clinton formation. The second well, on Lot 

 No. 40 of the same concession, passes through the blue clay 38 feet 

 6 inches. 



On another part of the same Lot 40, a well 42 feet deep passes 

 through red clay into quicksand. 



At this place it may be worthy of note that beds of limestone 

 and sandstone appear nearer the centre of the valley than the last 

 mentioned well.
