Thompson Canyon 2861 Yellowstone July 15, 1932. This afternoon I drove to Canyon with George Bagley. At the ranger station we met Dr. Bryant, Subst. Foll, Mr Edwards & Dr Bauer to discuss the Canyon situation. Dr. Bryant thinks there should be some way of abusing the bears such that they would become frightened & not loiter in the camps and along the roads. Mr. Foll thinks some such liquid gun should be perfected & asked that George Wright & I do so. None of them are yet willing to admit that any great expense for fencing camp areas & bear proofing garbage cans, parking areas, etc., is justifiable. Dr. Bryants party left in a few minutes for Old Faithful. George Bagley & I went to the seating ground. This evening there were more sets of cubes than last, and the whole crowd of grizzlies more agitated. They constantly roared & fought, and rushed from the platform to the woods (to the left of the audience where no one was protected) and back.
