In another part of his report Mr. Dowling states:—“Silurian limestone is found on Trout river, draining Mill lake, as well as in the bed of this lake just north of the trap rocks. The rocks at the narrows of the lake, described in the maps, as ‘high and romantic’ are cliffs one hundred and fifty feet in height of trap, capping horizontal beds of probably Animikie age. The trap overflow covers the uneven surface of these rocks, in much the same manner as Nipigon bay in Lake Superior. The underlying rocks are dark slates impregnated with iron ore, and interbanded with beds of jasper. Some of the beds seem to contain a high percentage of magnetite and hematite. On the east shore a section of about ninety feet of these jasper and iron-bearing slates is exposed above the lake, but on the west side they have been brought down to below the water level by a series of north and south faults and the exposures there are of trap alone. These rocks form an east and west ridge reaching to the lakes on the Washagami and eastward to a large lake on a branch of Trout river, which, as before stated, drains Sutton Mill lake and runs to the north.” Mr. Dowling reported iron ore in the vicinity of Sutton Mill lake, west of James bay, and south of Hudson bay. On the east coast of James bay and Hudson bay abundant evidence of iron ore had been discovered; in fact, two large islands, Taylor and Gillis islands, are said to be almost pure iron ore. Mr. D. B. Dowling, in his report of 1902 (Part F.F. Geol. Sur. Report) says:—“Small deposits of peat are to be found in various places, but the most important, from an economic point of view, is the area north of Lake Winnipeg described by Mr. Tyrrell. Along the valley of Burntwood river, where it is cut through the thick clay deposit, the general surface of the terrace is quite level. The drainage near the river is general, but back from the edge of the valley, on the more level parts, there is very often a wide expanse of swamp covered by a stunted growth of spruce and carpeted by heavy layers of moss. These swamps may at some future time supply peat for fuel.”
