Botany 
After a cessation of field work since 1933, one field party was sent out 
during 1935, which was largely engaged in botanical work. An area was 
selected that was comparatively unworked and that was important in 
connecting with work done by University of Toronto field parties during 
several seasons on Bruce peninsula, between lake Huron and Georgian 
bay, and the botanical work done on Keeweenaw peninsula, in northern 
Michigan. The party was in charge of Professor Robert C. Hosie, Faculty 
of Forestry, University of Toronto, with four botanical assistants. Although 
all the men were engaged in collecting plants and gathering general botanical 
data, Dr. Thomas M. C. Taylor and Dr. R. E. Fitzpatrick were princi- 
pally occupied with collecting and identifying plants. Andrew P. Leslie 
was largely occupied with studies of the soils and with photography, and 
Professor Iiosie and S. T. B. Losee with the ecological relations and 
enumeration of plant associations. Professor Hosie submits the following 
brief summary of the botanical work of the party. A more detailed 
report on the systematic botany and ecological work is in course of 
preparation. 
Biological Expedition in Batchawana Bay, Lake Superior 
The territory covered includes that section of Algoma region lying 
between the lake shore and a line from Mica bay, passing south of Pancake 
lake to a point where this extended line would cross Harmony river. 
The purpose of the expedition was to obtain collections and records 
of the flowering plants, mammals, and birds, and to gather information 
on the habit, ecological relations, and economic considerations, where pos- 
sible within the time available. 
From Mica bay southwards, for several miles along the shore-line 
the rock series of vegetation could be studied. From Coppermine point 
southwards the shores are variable, in places rocky, in places sandy 
beaches, and elsewhere stony. In Pancake bay and in practically all of 
Batchawana bay the shore-line is sandy and is bordered by flat, low-lying, 
sw r ampy lands extending inland in places for several miles. Paralleling 
the whole shore, within about 5 miles, the land rises info the rolling hill 
type so characteristic of the Algoma region. The area thus offers a great 
range of habitat conditions and presents a fruitful field for a biological 
study.
