OFFICIAL JOURNEYS. AT5 
the margin and coarser towards the interior of the mass. Proceeding to the Little 
Silver Mine (where one of the original discoveries was made) members saw the 
greywacké and overlying Cobalt quartzite exposed. A visit to the smelting and 
refining plant of the Mining Corporation concluded the tour, and, leaving Cobalt in 
the late afternoon, Swastika was reached at sunset. 
On August 17 an early start was made, and cars conveyed the party to Kirkland 
Lake, where Mr. J. B. Tyrrell met and entertained the company to breakfast. 
Mr. A. G. Burrows, of the Ontario Department of Mines, then explained the geology 
of the area, where syenite, porphyry, and lamprophyre intruding into the Timiskaming 
conglomerates had deposited gold-ore in veins. At the Lake Shore Mine specimens 
with visible gold were laid out for examination, and at the Tough-Oakes- 
Burnside Mine both gold and gold-tellurides were collected by the party on 
the ore-dumps. The extraction plant of the Wright-Hargreaves Mine was examined 
about midday. On the return to Swastika the car was joined on to the train for 
Timmins. 
Early on Monday, August 18, Mr. Burrows assembled the party for the excursion 
to the Porcupine area. Leaving the train at Dome Mine Station, the Timiskaming 
beds between this and the mine were carefully examined. The beds here were 
tilted at a fairly high angle and had suffered some metamorphism, though again not 
of an intense character. These strata had been injected by quartz porphyry, which 
had in the vicinity of the mine kept fairly close to the Keewatin-Timiskaming junction. 
The gold-bearing solutions had been accompanied by siliceous solutions, and the 
principal ore production is from the quartz veins associated with the Timiskaming 
sediments as distinct from the conditions at the Hollinger Mine, where veins in the 
Keewatin greenstones yield the bulk of the ore. It is true, however, that there is 
some gold production from the Keewatin junction at the Dome. After lunch at the 
Dome Mine the afternoon was spent examining the pillow-lavas of the Keewatin 
series, but near the Dome the junction of the Timiskaming with the Keewatin was 
pointed out. The party split up at the Paymaster Mine, some returning to Timmins 
via the Vipond Mine and others via the Hollinger or the McIntyre. 
Early next morning the general party arrived at Timmins. Mr. Burrows again 
led a small party to see some of the rocks round the Hollinger Mine. Intrusions of 
quartz porphyry into the Keewatin lavas were again noted, and one remarkable 
example of pipe intrusion gave a wonderful idea of the gradation between bulk injection 
and lit-par-lit injection as seen in other areas. The mine itself was now entered and 
the general process of gold-extraction followed from start to finish. 
From Timmins the excursion proceeded to Iroquois Fauts (492 m., 
905 ft.), where the works of the Abitibi Power and Paper Company are 
situated—modern pulp and paper mills, producing almost entirely news- 
print, which the members thoroughly inspected in small parties under the 
guides detailed by the Company. Power is derived from the Iroquois and 
Twin Falls on the Abitibi River. The town is built on ground leased to 
the Company for ninety-nine years and is laid out on the lines of a garden 
_ city (contrasting strongly with the mining towns visited). In addition to 
~ 
houses, the Company provides a hostel for employees who cannot be 
otherwise accommodated: this serves also as an hotel. While the 
Company is the overlord, local affairs are largely in the hands of an elected 
municipal council, which levies rates and manages the school, public 
gardens, athletic grounds, etc. The stores, laundry, tea-rooms, and 
various other institutions are to some extent under the supervision of 
the Company. 
The trains reached the main transcontinental line of the Canadian 
National System at Cochrane, and turned west along it, leaving Northern 
Ontario and entering Manitoba near White (1201 m.). 
Wednesday, August 20.—WinnieEG, the capital of Manitoba (1294 m., 
772 ft.), was reached in the evening, and the party was met by members of 
the local committee. Here many acquaintances dating from the meeting 
_ of the Association in the city in 1909 were pleasantly renewed.
