lies ioo miles to the southeast, south of the height of land. 

 The divide between the Hudson Bay and the St. Lawrence 

 waters is not pronounced, being only about 1,300 feet 

 above sea level. 



The highest elevation near Porcupine is along the south 

 boundary of Jamieson, where a felsitic ridge has an altitude 

 of 1,350 feet above sea level. 



The country from Night Hawk lake to the Mattagami 

 river is one of low relief. Occasional ranges of hills reach 

 an elevation of 150 feet, but generally abrupt changes in 

 elevation are less than 50 feet. Often in a low area rocks 

 outcrop only a few feet above the surrounding drift and are 

 only a fraction of an acre in extent. Northwest, south, 

 southwest and southeast of Porcupine lake the country is 

 somewhat elevated, and rock exposures are more frequent 

 than in most of the area. 



The; First Prospecting. 



Previous to the building of the Temiskaming and 

 Northern Ontario railway, the area was difficult of access 

 and little prospecting was done in it until 1909. 



In 1906 some work was done by prospectors on a vein 

 near Miller lake and a few hundred feet from the present 

 Hollinger vein. Evidently seeing no gold, and having no 

 assays made, they abandoned the property. In the same 

 year claims were staked in Shaw township on what is des- 

 cribed in the application as a " vein of sugar quartz and 

 hematite iron." This is of interest since the so-called vein 

 is simply the upturned edges of the Keewatin iron-form- 

 ation. 



In 1908 claims were staked by Mr. H. F. Hunter on the 

 east shore of Porcupine lake in Keewatin formation. Gold 

 was found disseminated through quartz and schist in a 

 sheared zone. 



It was not, however, until the following year that the 

 spectacular discoveries of J. S. Wilson, on what is now 

 the Dome property, caused a rush to the district, and in a 

 few weeks practically all of Tisdale and a great part of the 

 adjoining townships and unsurveyed territory were staked 

 out in mininsr claims.
