Part Fig-. 46a.—Good roads at Cobalt. 1913 Cobalt=lNickel Arsenides and Silver 107 PALHOZOICSilurian Limestone It will be seen from the map (scale 1 mile to the inch), that the Niagara andClinton limestone forms some large outcrops on the islands and in the vicinity of theshore near the northwest corner of lake Temiskaming. This limestone affords stonesuitable for building and for the production of lime, and on this account should be ofconsiderable value in the years to come, since the rock is a somewhat rare materialin most of this northern part of Ontario. The district to the west and north is beingrapidly settled and will soon contain a large population which will need much materialfor building purposes. The following is an analysis of a sample of limestone takenfrom Fairs quarry, Haileytuiy:
