Turner Philip
Entered the service of the Hudson's Bay Company about
1779, and carried out important surveys for the Company. Stationed at
Cumberland House in 1789, and while there gave David Thompson
instruction in practical astronomy. Between 1790 and 1792 made a survey
of Lake Athabaska, and of the canoe route from Cumberland House to Great
Slave Lake. Dr. J. G. Kohl says that his manuscript journal of a
Journey from Cumberland-house towards the Athapiscow Country and back
to York Factory, 1790-1792, is preserved in the archives of the
Hudson's Bay Company at London. His map of this region, the original of
which is also in the Hudson's Bay Archives, is reproduced in Burpee's
Search for the Western Sea. His careful survey of Lake Athabaska was
important in that it corrected Peter Pond's crude map, which placed the
western end of the lake as far west as 131 deg., and so gave rise to the
impression that the lake was within easy reach of the Pacific Ocean.
