Note 36 — Chapter III

The Manitoulin islands stretch from east to west along the north shores of Lake Huron, and consist chiefly of the Great Manitoulin or Sacred Isle, Little Manitoulin or Cockburn, and Drummond. Great Manitoulin is eighty miles long by twenty broad. Little Manitoulin has a diameter of about seven miles. Drummond is twenty-four miles long, with a breadth varying from two to twelve miles. It is separated from the American shore, on the west, by a strait called the True Detour, which is scarcely one mile wide, and forms the principal passage for vessels proceeding to Lake Superior.
