In his new publication on the illustrated letters of C.M. Russell, Brian Dippie makes the following remarks on Russell's letter to his friend Jim Bollinger: "Charlie sounded notes of both nostalgia amd anticipation in his letter to Judge Bollinger, his hunting companion in 1919, 1920 and 1922. Bollinger thought the sketch of their cavalcade crossing the South Fork of the Flathead River the previous October 'as life like as a photo', with John Lewis nearly across the river and Charlie and the judge ("the biggest and fattest, on the biggest and fattest horse") bringing up the rear. While they were entering the water, Charlie had remarked, 'Gee, that's a fine picture'" (p.333.) This scene was the inspiration for When Horses Turn Back, There's Danger Ahead in the collection of R.W. Norton Art Gallery in Florida.
