Jennings: Notes on Pteridophytes 39 



miles north of Nepigon. Mr. Daily remained with the 

 writer until the first week in September and was of great 

 assistance in many ways, although not officially posing 

 as a collector. Mrs. Jennings joined us about the first 

 of August and was of great assistance in the work, as 

 from that time on until the end of the season the weather 

 was one continual round of cold drifting rains and fogs 

 which made the preparation of suitable collections very 

 difficult. 



The general features of the region covered in this work 

 are quite diversified — rounded rocky hills and knolls, 

 steep cliffs, well-developed talus-slopes, fiord-like inlets, 

 great and numerous bogs and lakes, and cold swift- 

 running streams. At Fort William is an extensive allu- 

 vium-filled valley elevated but a few feet above the 

 level of Lake Superior and through which the Kamin- 

 istiquia River empties in the form of a branching delta. 

 All along the North Shore are areas of sand and gravel 

 terraces which have been formed when the lake was at 

 various higher levels. Remains of at least five such 

 terraces arranged in a surprisingly uniform sequence are 

 to be seen along the north slope of the Sleeping Giant at 

 Sawyer Bay. 



The forests of the whole region have been lumbered 

 and burned over, although in a few places were found 

 small areas of apparently primeval growth. Near Fort 

 William are the northern limits of the hard maple and 

 American elm and through the whole region the forests 

 are quite uniform and consist of but few species. On the 

 sand and gravel terraces the Banksian pine rules, in the 

 bogs and poorly drained lake borders the tamarack and 

 black spruce; on poorly drained flats over clay or other 

 impervious soil the black spruce occurs practically pure; 

 in wet, but well-drained places, as at the outlet of a small 

 lake where a swift running stream keeps the water in 

 motion, the arbor vitae prevails, as it does also on rocky
