August 27, 1921: "On his return from Oakridge, Mr. MacDuff visited Hardesty lookout, where Ranger C.B. McFarland is erecting a lookout house. The house is a standard type which is purchased ready-cut, and is hauled and packed to the lookout. In spite of the difficulties of packing some four tons of lumber, ranging up to 12 feet long on mule back up a 25 to 30 per cent trail grade, Mr. McFarland is progressing very satisfactorily and it is hoped that the building will be completed within a day or two. In hauling the lookout house from the railroad to Hardesty, Mr. McFarland must have borrowed the renowned Paul Bunyon's mule team, since he succeeded in hauling by wagon two or three miles up the mountain side until stalled by a high center on a hogback ridge, from which point he was compelled to pack on mule back, said the supervisor. Mrs. Walter Allan, formerly Nell Southworth, is the lookout on Hardesty." (Morning Register)
