Miles and 

 Kilometres. 



38 m. Cartier — Altitude 1,364 ft. (415-7 m.). 



61 km. Leaving Cartier, the first three miles (4-8 km.) 

 is over typical Laurentian granite and gneiss. 

 Near Geneva is a contact with Keewatin, and 

 for about 10 miles (16 km.) most of the rock is 

 of the typical Keewatin traps, in some instances 

 highly altered. This rock again gives place 

 to the Laurentian 12^ miles (20-1 km.) west of 

 Cartier, and with two exceptions the Laurentian 

 continues uninterrupted to Chapleau, the next 

 divisional point. The two Keewatin outcrops 

 visible in this distance are between Roberts 

 and Ramsay. 



109 m. Ramsay — Altitude 1,403 ft. (427-6 m.). 



176 km. 



176m. Chapleau — Altitude 1,418 ft. (432-2 m.). 



283 km. The rock between Chapleau and White River 

 are mainly Laurentian and exhibit the 

 typical rounded hills formed by glaciation, 

 the valleys between which frequently contain 

 lakes and swamps. Four Keewatin areas are 

 crossed in this interval. The first of these is 

 about two miles wide (3-2 km.) and is first seen 

 9! miles (15-3 km.) west of Chapleau. The 

 second and third are probably connected, 

 though on the railroad they are separated by 

 a band of Laurentian about three miles (4 • 8 km.) 

 wide. These exposures are about equal in 

 width, and the first of them extends from 



236 m. 425 miles (68-4 km.) west of Chapleau, 



380 km. the milepost 58, and the third one begins one 

 mile (i-6 km.) west of Missinaibi and 

 extends for n§ miles (18-5 km.). The fourth 

 is a small outcrop one mile (i-6 km.) west 

 of Williams. 



307 m. White River — Altitude 1,230 ft. (374-9 m.). 



494 km. At White River, a divisional point on the 



railway, yards have been built for feeding and 



resting cattle in transit.
