dications of useful minerals were found in this formation. The colour 

 Gneiss. i* s usually some shade of grey, generally rather light, but sometimes it 



is reddish-grey, and more rarely a distinct red or pink. The stratifi- 

 cation, which in most parts is moderately distinct, is often bent or 

 contorted. In some places the gneiss has a spotted appearance, and 

 occasionally strongly contrasting beds are seen, but, as a rule, it is of a 

 very uniform character. Its average texture is of the medium variety, 

 or rather tending to be fine-grained, but coarse forms are occasionally 

 seen. Judging from the specimens and Mr. Cochrane's description, an 

 area of very light grey, fine-grained granite occurs on the south-east 

 side of God's Lake, about midway between the Narrows and the north- 

 east extremity; and another, probably of small extent, of light grey, 

 coarse granite at the outlet of Beaver-hill Lake. The latter consists of 

 plates of yellow mica in white quartz and feldspar. Both of these 

 localities are surrounded by Laurentian gneiss. 

 Character and In order to save a more tedious description, the general character 

 and the strike of the gneiss throughout the region explored by Mr. 

 Cochrane is here given in tabular form. It will be evident from this 

 that no prevailing or general direction can be detected in this part of 

 the country. The bearings are all magnetic.
