lakes and ponds, those in the sand-plain often being 
without outlet, other than by seepage. 
The latter part of the 1917 trip was spent along the 
Canadian Government Railway, northwest of Lake 
Superior, first at Hunt, and then back to Oscar, about 
one hundred and sixty-eight and one hundred and eight 
miles, respectively, northwest of Fort William. At 
Hunt the country consists of morainal knolls and ridges, 
the deeper hollows being occupied by muskegs or by 
lakes, of which there are a great number, large and 
small. At Oscar much the same topography prevails, 
but with more sand and gravel in the morainal de- 
Posits and with some considerable areas of sandy plain. 
Here also the lakes are very numerous, and, as at Jellicoe, 
some of those in the sand-plains are without outlets. 
To briefly summarize: The localities visited during 
the five Seasons have included, for usually about two 
Weeks’ stay each, the following main stops (or bases) 
along the north shore of Lake Superior: Heron Bay, 
hear the mouth of the Pic River; Rossport; Nipigon: 
Fluor Island ; Magnet Point; Porphyry Island; Silver 
Islet, Thunder Cape; and Fort William; and the follow- 
ng inland stations: Longuelaec, north end of Long Lake; 
Jellicoe; Orient Bay, at the south end, and Ombabika 
Post at the north ‘end of Lake Nipigon; Slate River , 
about three miles southeast of Stanley and fifteen miles 
West of Fort William; Loon Lake; Oscar; Hunt; and 
Sioux Lookout, or Graham. Many other localities, 
often at some distance from these bases, were visited 
briefly, such as St. Ignace Island; Jackfish; Kakabeka 
alls; first rapids of the Kenogami; Pelican Falls, south 
Side of Lac Seul, etc.; while the region within a radius of 
five to ten miles of the main bases was explored pretty 
thoroughly, The explorations have thus covered a 
“ritory of about 200 miles along the north shore of 
ake Superior, and many of the islands and peninsulas
