It includes two peninsulas of unequal size, in addition to which are numerous islands, constituent parts of the territory.

The most important of these is Michilimakinack, already described.

This island, while in the former possession of the British, was the general rendezvous of the North-West traders and the Indians they supplied.

Here the outfits were furnished for the countries of Lake Michigan and the Mississippi, Lake Superior and the North-West; and here the returns of furs were collected and embarked for Montreal.

Detroit, the chief town of the territory, is situated on the right bank of the strait, 10 miles below Lake St.Clair and 28 miles above Lake Erie.
