"On the way our chum, Jimmy here, happened to shoot a hawk that had pounced down on a flying pigeon. Wrapped around one of the pigeon's legs was a piece of tissue paper, and bearing a message. I have it here with me, and both the hawk and the pigeon are in one of our packs on the burros. This message was not signed, but it plainly announced that there are five untrustworthy men employed on this place who are in league with cattle rustlers."
