which caused us to make many portages, and so we arrived on the 31st at Kettle falls. The rock which here arrests the course of the Ottawa, extends from shore to shore, and so completely cuts off the waters, that at the time we passed none was seen falling over, but sinking by {356} subterranean channels, or fissures in the rock, it boiled up below, from seven or eight different openings, not unlike water in a huge caldron, whence the first explorers of the country gave it the name of Chaudière or Caldron falls.
