FUNK ISLAND. YELLOW OCHRE.

of very soft sandstone, about one foot in thickness, con- 

 taining a vast number of stains, which seem to have been 

 occasioned by fucoids. 



At Little Grindstone Point, the limestone No. 4 of 

 Deer Island comes to the water's edge. The sandstone 

 No. 3 is just below its level. Little Grindstone Point is a 

 little more than seven miles south-west of Big Grindstone 

 Point, and the altitude of the limestone, where it touches 

 the sandstone at the last-named place, is about twenty-five 

 feet, which would give an inclination of a sectional expo- 

 sure in a south-westerly direction of about three feet in 

 the mile. It appeared, however, to have a slight westerly 

 dip, showing the true dip to be a few degrees more to 

 the west than south-west, as was afterwards ascertained. 

 In the limestone, turbinated shells are numerous, with 

 Orthoceras of large dimensions. The scenery is attractive, 

 and, in a geological point of view, eminently interesting. 

 The opposite coast is formed of the unfossiliferous rocks 

 belonging to the great Laurentian Series, which extends 

 from Labrador to the Arctic Ocean. Within three miles 

 of Grindstone Point, islands of this important formation 

 occur a short distance in advance of the east coast, which 

 is wholly composed of it. 



The depth of Lake Winnipeg immediately opposite 

 Grindstone Point is forty-eight feet. A storm afforded us 

 another opportunity of examining the fossiliferous rocks 

 of this locality, for no sooner had we started in the direc- 

 tion of the " Granite Islands," opposite the point, than 

 the wind turned round to the north and compelled us to 

 seek shelter in a bay of Punk Island, three miles south- 

 east of the Grindstone Point. 



On Punk Island, strata 1, 2, 3, and 4 of Deer Island 

 were recognised in a bay, with some lithological dif- 

 ferences. In Nos. 1 and 2 here, which could scarcely be
