Photograph by Frank S. Davis, September 11. The author stated: " One of them is dated September 11, 1893; the other two were taken the winter following. I do not remember to have copied any previous photographs or drawings in making my markings on the rock. Going back to my school days, I can remember going to the rock and taking chalk and marking in the lines. There would be a number of us and we would all work at it and talk about what they were put there for. So you see I had seen the lines marked in a good many times. Then in after years I got a camera and got quite interested in taking pictures. One of the photographs I made for some one who was writing a book at that time, but cannot remember the name of the writer or that of the book.
