'Nash had blinded up in a dense thicket of willows along the edge of a clear channel some 150yards from my own stand (Col. H.P. Sheldon). A pair of mallards traveling high and in hurry went over Nash. Both collapsed and after a moment of complete silence the double boon of the big came rolling roundly over the marshes. It sounded exactly like two solo notes from the bass horn in a symphony orchestra, and I mentioned it to Nash when we got back to the lodge. Bo Whoop, Bo Whoop.'
