Then one day, unexpectedly, they came upon two trappers by a beaver-dam.
A beaver-dam thus tends to distribute to the streams below it a moderate quantity of water each day.
A small river also flowed across our way from the right, and we passed it over a beaver-dam.
One of the prettiest additions is a beaver-dam, with picturesque and tower-like crag for the larger specimens of the Falco tribe.
