September 1937: "For a new ranger, I have a conviction that Ranger Harold Bowerman, of the Diamond Lake District, is second to none so far as nasal "observations" are concerned. Why do I think so? Listen! During a recent electrical storm, the Umpqua suffered many "strikes". So much rain followed the storm that sleeper fires have been considerably in evidence, so noses as well as eyes have been brought into use to detect any possible hangovers. Specifically, Ranger Bowerman and the writer were following along one of the Umpqua trails directly down a steep slope and possibly 1000 feet, or more, lower than Rattlesnake Lookout Point, when Bowerman, who was pulling the pack mule (with all four feet dragging) yelled to me (riding in the lead), "Do you smell anything unusual?" I had to admit that I did. We reasoned that it might be the Lookout (or his smoke) and it might be something alive from a "strike". When the Lookout was reached, we questioned him and he said that lightning evidently came down in the suspicious locality but no smoke had ever shown up. Anyway, the lookout made an investigation upon our departure from his station, and later in the day advised that he had found fire in an old stump in the heavy timber below the lookout point. Some nose! V.V. Harpham" (Six Twenty-Six)
