the well at selkirk. 



In the spring of 1894, a supply of water for the Selkirk fish hatchery, 

 other than that of the Red River, being required, a well was drilled and 

 a supply obtained after penetrating three hundred feet. The first or 

 upper part was through 97 feet of til!, then to a depth of 264 feet in 

 limestone, reaching a dark shale, in which sandy layers, containing 

 gravel, gave a sufficient supply of water. The specimens obtained from 

 the drilling, show that the limestone through which the drilling was 

 made, consists in the upper half of semi-crystalline light yellow beds, 

 similar in a great measure to those rocks exposed at Selkirk and Lower 

 Fort Garry. 



At a depth of 185 feet, or 88 feet below the top of the limestone, 

 a series of beds about 9 Let in thickness, were called by the drillers, 

 sandstone, but it is found from the specimens to be mostly a band of 

 fine grained limestone, through which cherty masses are scattered. The 

 percentage of silica is low, being under ten. Examples of this rock 

 are very probably to be seen at Cat Head, on the west shore of Lake 

 Winnipeg, where the cliff is of a fine yellow magnesian limestone, and 

 the lower beds well pitted with small cherty concretions. 



The specimens from the lower part of the limestone in the well, 

 are all of a light colorued limestone, somewhat coarser in texture than at 

 the middle of the section, and are, no doubt, similar to the limestone 

 of the shores of the lake at Grindstone Point and Dog Head. The 

 thickness from the cherty layer to the base of the limestone was 79 feet, 

 or a trifle more than that measured on the lake.
