Note 149 — Chapter IV
Reading edition
"The Falls of the Rideau are about fifty feet in height and 300 in breadth, being, at the time we saw them, more magnificent than usual, by reason of the high state of the waters. It is from their resemblance to a curtain that they are distinguished by the name of Rideau, and they also give this name to the river that feeds them, which again lends the same appellation to the canal that connects the Ottawa with Lake Ontario."—Simpson, vol. i., p. 16.
