308 G. S. Hume — Stratigraphy and Geological Relations 



On the ridge of rock extending northwest from Wabi 

 peninsula, there is no possibility of obtaining artesian 

 wells, and the chances for finding water close to the sur- 

 face are not good. The top part of this ridge is of resist- 

 ant rock, but at lower horizons shales occur, and the ero- 

 sion on these less resistant strata has caused the ridge to 

 be bounded on the east by a rather steep cuesta face which 

 extends northwest from the west side of Sutton bay. 

 East of this cuesta face, the country is very little above 

 the level of the lake, but rises gradually towards the 

 north. In this flat, extending as a narrow strip not more 

 than 3 to 4 miles wide, there is again suitable structure 

 beneath the clay for favorable water supply, and already 

 one artesian well has been found. In the part of the Clay 

 Belt underlain by Precambrian rocks there is a possibility 

 of finding water on the contact of the Precambrian and 

 clay deposits in the depressions between the knobs and 

 ridges of rock. 



Limestone. — Limestone of the Lockport formation is 

 used in the manufacture of lime, and rock of both the 

 Lockport and Haileybury formations has been used as 

 building stone. 



In the sulphite plant of the Abitibi Power and Paper 

 Co., Iroquois Palls, limestone low in magnesium content is 

 required in the manufacture of paper pulp. Rock of the 

 Haileybury formation has been used for this purpose, but 

 the present quarry is rather unsuitable on account of , the 

 alteration that has occurred in the top weathered portion. 

 However, it is hoped that more favorable results can be 

 obtained from a new quarry. 



Clay. — The banded clay of Lake Barlow has been used 

 in the manufacture of brick and tile. The clay contains 

 too high a percentage of lime to make the best brick-form- 

 ing material, but by the addition of finely ground diabase 

 from the Cobalt mills, instead of sand, which is not avail- 

 able, a suitable quality of building brick is obtained. 



There are red clays and shales at the base of the Hailey- 

 bury formation that may be of future economic impor- 

 tance. These clays and shales in a diamond drill core 

 from the west of Haileybury were 50 feet thick. Mr. 

 Keele of the Department of Mines of Canada has investi- 

 gated this material and finds it to be satisfactory, as it 

 does not begin to soften below a temperature of about
