or perhaps somewhat higher and more erect. But I did see, and very many
times, jets of water or spray rise into the air at the rear of drakes
which were passing in line before the females. These were similar in
every respect to those when the Whistler drakes throw up when "bleating"
but the jets produced by the Gooseanders rose to a the greater height and
