were found at Wekusko lake, and samples of iron ore at Sipiwesk lake, and careful prospecting might perhaps disclose deposits of commercial value, but everywhere else so far as observed, the obtruding bedrock was either pure granite or limestone. The latter, however, is mostly dolomite, the variety used as a flux in the reducing of iron ores, and future ore discoveries may give rise to such demand. This dolomite also will prove a valuable building stone for prairie towns, when made available by the Hudson Bay Railway.” According to Mr. McLaggan (See p. 58) the section of country about Reed lake is very rocky. Dark coloured granite, streaked with white quartz, extends along the lower end of the lake and for six miles along the river. Four miles farther Mr. McLaggan found indications of iron and saw a good water power. Above Herb lake he saw another splendid water power, very easy to develop, and along the river below rapids in five places from which fair power could be generated. At the lower end of Herb lake and along the river, granite mixed with white quartz was seen, and at the falls in the river, about twenty miles below the lake, good slate was found. On this lake Mr. McLaggan noted indications of iron. In places along and back from Grass river, on either side, quartz was seen. The country has been burned over, leaving only a few bunches of spruce, and the surface of the rock has been well exposed, so that prospecting would be easy. Mr. McLaggan thinks that this part of the country may prove rich in mineral. On September 10, Mr. McLaggan reached Paint lake. Quartz was still in sight, but not so frequent in occurrence. There are a number of islands in the lake with rocky shores and small, mixed timber. Below Elbow lake the river banks are high, the country becomes rougher, and fire has bared the rocks of soil. White quartz crops out in considerable quantities. Along the banks of Cumberland lake there are considerable quantities of limestone, which may “become very valuable in time.” Speaking of the region explored, as a whole, Mr. McLaggan considered that as a mineral country it offers a wide field for prospectors. “In the country travelled over there are indications of gold, silver, iron and limestone, and Indians and white men from the north tell wonderful stories of a place called Indian lake, north of Nelson House, and of an island on Burntwood river where various minerals and oil are said to exist.”
