SUPERFICIAL GECLOGY OF DUNDAS VALLEY. 1 39 



fresh and apparently bear no relation whatever to the waters under- 

 neath. 



Nor is this band lying in a straight line between the two forma- 

 tions — that is, between the Onondaga and Niagara — but, from what 

 can be gathered from the position of the wells of sulphur water, they 

 follow a line along the Grand river from Paris to Onondaga, and 

 then branch around toward the head of Dupdas valley. 



These wells are found on Lots 30, 31 and 39 of the IV. Con- 

 cession of Ancaster, and again at the Sulphur Springs, about two miles 

 west of Ancaster. The analysis of this water made in 1858, by Dr. 

 Wilson, gives : — 



Chloride of Sodium t 3>5476 



Chloride of Potassium 0052 



Chloride of Calcium 1-3528 



Chloride of Magnesium 4*9° 



Sulphate of Lime 6500 



Carbonate of Lime 2 °35 



Carbonate of Magnesia 0160 



Carbonate of Iron 0274 



Silica 0097 



Organic matters, Phosphoric Acid, Alumina and 

 Iodine Traces. 



Total 6. 23 1 2 



The carbonates are bi-carbonates. The sulphuretted hydrogen 

 5.6 inches to 100 inches of water. The spring is slightly thermal. 



In addition to these Sulphur springs, there are also saline springs 

 running in a direction nearly parallel to the sulphur. On lot 34 of 

 the III. Concession of Ancaster, a well gives brackish or salt water, 

 and on Lot No. 39 of the I. Concession of the same Township a 

 salt well is found. This well was considered of sufficient strength to 

 warrant an attempt to make salt being made. Again, in the valley, 

 a well charged with salt is reported. There is also a saline well in a 

 brook near Dundas. 



Sulphur springs are by no means rare in districts overlaid by the 

 Niagara group, but the peculiar positions of these springs in this dis- 

 trict seem worthy of remark.
