164.7 m - Altitude 1,007 ft. (306.9 m.). The town of 



265. km. Swastika is underlain by conglomerate which 

 contains numerous pebbles of porphyry and 

 jasper, while the high ridge southwest of the 

 town is also conglomerate. Numerous narrow 

 dikes of red feldspar-porphyry intrude the con- 

 glomerate for two miles beyond Swastika. 



Conglomerate and greywacke are shown in 

 the cuttings as far west as Kenogami station. 



168.16 m. Altitude 1,013 ft. (308.8 m.). In the cutting 



270.4 km. south of Kenogami station, the conglomerate 

 and greywacke have a vertical dip. This con- 

 glomerate has been provisionally classed as 

 " Temiskaming." The glacial striae seen on the 

 polished surfaces near Kenogami strike S. 



55° E. 



Another Keewatin greenstone area extends 

 north of Kenogami to mileage 178^2. At the 

 fourth crossing of the Blanche river there is 

 basalt which is intruded by a dike of porphyritic 

 diabase. 



At mileage 169 is a basalt which has been 

 crushed to a friction breccia. 



On approaching Sesekinika lake there are 

 several dikes of fresh quartz-diabase. At 

 mileage 172 one of these has a width of 60 feet. 



175.56m. Altitude 1,022 ft. (31 1.4 m.). Sesekinika 



282.4 km. lake contains numerous islands on which 



Keewatin rocks occur. On account of its 



picturesqueness this lake has been reserved as 



a summer resort. 



HEIGHT OP IvAND. 



The divide between the St. Lawrence and 



Hudson Bay waters is crossed at mileage 177^. 



At mileage 178^ the Keewatin greenstone is 



intruded by dikes of hornblende syenite. 



Numerous large boulders of conglomerate of 



the Cobalt series are scattered along the risrht of
