After Champlain: from Montreal to the Mississippi A very remarkable series of further explorations were carried out as the indirect result of Champlain's work.

In 1610 he had allowed a French boy of about eighteen years of age, named ETIENNE BRULE, to volunteer to go away with the Algonkins, in order to learn their language.

Brule was taken in hand by Iroquet,[1] a chief of the "Little Algonkins", whose people were then occupying the lands on either side of the Ottawa River, including the site of the now great city of Ottawa.

After four years of roaming with the Indians, Brule was dispatched by Champlain with an escort of twelve Algonkins to the headwaters of the Suskuehanna, far to the south of Lake Ontario, in order to warn the Andastes[2] tribe of military operations to be undertaken by the allied French, Hurons, and Algonkins against the Iroquois.

This enabled Brule to explore Lake Ontario and to descend the River Suskuehanna as far south as Chesapeake Bay, a truly extraordinary journey at the period.
