Note 27 — Chapter III
Reading edition
The Mattawan has its source on the very verge of Lake Nipissing, so that it was easy to make a "portage" there to reach the lake. The Indians, and afterward the French, passed by the Mattawan, Mattouane, or Mattawin ("the residence of the beaver"), went over the small space of land called the "portage," that exists between the two waters, floated on Lake Nipissing, and followed the French river, which flows directly out of that lake to the Georgian bay.
A "portage" is a place, as is well known, where parties had to "port" their baggage in order to reach the next navigable water.
