Temagami lake is one of the most beautiful 

 sheets of water in Northern Ontario, a fact 

 which caused the building of three summer 

 hotels on its shores. The railway station lies 

 at the east end of what is known as the North- 

 east Arm of the lake. A few hundred yards 

 north of the station conglomerate of the Cobalt 

 series may be seen resting on the jagged edges 

 of Keewatin greenstone schists. While to the 

 west of the track about two hundred yards 

 splendid outcrops of the Keewatin iron formation 

 (jaspilyte) occur. The latter, which is 1,000 

 ft. wide in places, is easily reached by a foot- 

 path, and consists of silicious magnetite inter- 

 banded with variously colored jaspers and cherts, 

 with in some instances a small proportion of 

 hematite. 



94. m. Between Temagami and Latchford, altitude 



151.2 km. 922 ft. (281 m.), the railway passes successively 

 over granite, conglomerate, slate-like greywacke, 

 quartzite, diabase, and red, banded greywacke. 

 The latter is well exposed on the cliffs bordering 

 the railway south of Latchford. 



98. m. For the next four miles, as far as Gillies, 



157.6. km. altitude 934 ft. (284.6 m.), the railway closely 

 follows the Montreal river, which empties into 

 lake Temiskaming 21 miles to the southeast. 

 At Latchford the river, which for the most part 

 pursues a steady southeasterly course, bends 

 sharply to the northeast until Gillies station is 

 reached when it takes its normal direction again 

 to the southeast. Below Gillies several miles, at 

 Hound and Ragged chutes, important falls on 

 the Montreal river have been utilized to supply 

 compressed air and electric energy for the silver 

 mines at Cobalt. At Ragged chute the air is 

 compressed by a simple and ingenious hydraulic 

 method, and is conveyed directly to Cobalt in a 

 24-inch pipe.
