H5 



fire was attended by a great loss of human life, 71 in all 

 having lost their lives either by being burned, suffocated or 

 drowned. 



Timber. 



In the parts which have escaped the fires there is a 

 dense growth of timber, including white and black spruce, 

 jackpine, birch and poplar. It is interesting to note that a 

 growth of young tamarac is replacing the old tamarac trees, 

 which have all been destroyed in recent years by the larch 

 saw-fly. 



GEOLOGY. 



The compact rocks of the area may all be referred to the 

 pre-Cambrian. and are similar to those of the Cobalt area, 

 described on preceding pages. However, only the Keewatin 

 and Temiskaming series are of importance in the part of 

 the area that is productive at present. The following table 

 shows the age relations. 



Pleistocene. 



Post-Glacial. — Stratified clay, sand, and peat. 

 Glacial. — Boulder clay. 



PrE-Cambrian. 



Later Intrusives. — Quartz-diabase, olivine-diabase, etc. 

 Igneous contact. 



Cobalt Series. — Conglomerate. 



Unconformity. 



Temiskaming Series. — Conglomerate, quartzite, grey- 

 wacke, slate or delicately banded greywacke. 

 Unconformity. 



Laurentian. — A complex of granites older than the 

 Cobalt series. It intrudes the Keewatin, but its relation- 

 ship to the Temiskaming is not definitely known ; it may be 

 in part older and in part younger than the Temiskaming 

 series. 



Igneous contact.
