His brigade was moving up the Columbia when they saw canoes approaching.

Then a child’s voice called out in French: “Stop, stop.”

They stopped.

They recognized Marie Dorion and her sons.

The use of French is notable.

Marie’s sons had grown up in the multilingual world of the fur trade, where French was the common language of the voyageur culture that formed the workforce of the enterprise.

French was, in a sense, the first language of the fur-trade frontier — the language in which orders were given, accounts were kept, and relationships between the various cultural communities of the trade were negotiated.

Marie’s sons knew to call out in French because French would be understood by any fur-trade canoe brigade on the Columbia River.
