5 of 1888 the descended the Mackenzie to the Peel which he ascended to Fort McPherson. After making an exploratory trip up Rat river he crossed to Lapierre house by way of Peel River portage, descended Porcupine river, and carried on explorations in Yukon. In 1889 and 1890 McConnell explored the country Gee Athabaska and Peace rivers north of Lesser Slave lake. A careful examination was made of the | geology along the Athabaska from Little Slave river to its mouth and along the Peace from Smoky river to Mikkwa river, and the more Poa tributaries were ascended. The south shore of lake Athabaska was explored by D. B. Dowling in 1892, and the north shore by J. B. Tyrrell in 1892 and 1893. Cree river and the system of lakes and rivers to the east of lake Athabaska were also explored by Tyrrell and Dowling. During the summer of 1899 explorations on Great Slave lake were conducted by Robert Bell and his assistant J. M. Bell. The latter remained at Resolution during the winter of 1899-1900 and in 1900 explored Great Bear river and the north and east shores of Great Bear lake. He made a traverse to Coppermine river, and returning to Great Bear lake reached Slave lake by a canoe route formed by a series of lakes and streams between McTavish bay and the north arm of Great Slave lake. During the summer of 1902, Charles Camsell carried on explorations in piled country to the west of Slave river, making an overland traverse southwest from Fort Smith to Salt river and Little Buffalo river, and following Jackfish river to the Peace. In 1905 he made a reconnaissance survey of Wind and Peel rivers. Entering Wind river by Nash creek he descended it to its confluence with the Peel which was descended to below mount Goodenough. | In 1907-8 Joseph Keele made surveys on the Pelly, Ross, and Gravel rivers, descending the last-named from its source to its junction with the Mackenzie. Parts of the field seasons of 1918, 1914, and 1915 were spent by S. C. Ells in an investigation of the bituminous sands of Athabaska river. During the summer of 1914 Charles Camsell explored a section of country along Tazin and Taltson rivers between Athabaska and Great Slave lakes. In the same year a study was made by F. J. Alcock of the geology of a portion of the north shore of lake Athabaska. Further investigations were carried on by Camsell in 1915, by Camsell, Alcock; McLearn, Cameron, and MacVicar in 1916, and by Kindle, McLearn, and Cameron in 1917.
