 With a tree-lined river bank dominating the top and back of the frame, the Charles River flows toward a stationery camera. A flotilla of canoes passes by. Some have one occupant, some two, a few three or four. Some men wear ties, a few wear boaters. Only a handful of the canoes have more than one paddler. None go quickly. There are more than 40 canoes packed close together. Off camera, down left, they seem to make a circle and head back to enter the frame from the left.
