He became a power among the Indians.

With Scottish shrewdness Henry acquired from the Commandant at Mackinaw the exclusive right to trade on Lake Superior.

He became a partner of Cadot, and they made a voyage as Canadian Argonauts, to bring back very rich cargoes of fur.

They even went up to the Saskatchewan on Lake Winnipeg.

After Henry, came another Scotchman, Thomas Curry, and made so successful a voyage that he reached the Saskatchewan River, and came back laden with furs, so that he was now satisfied never to have to go again to the Indian country.
