As mentioned, Devereux Emmet wrote this in 1913:
"The ninth (Piping Rock) is a very uncommon hole. I have never seen one like it. There are two large greens, one beyond the other, with a hollow between them and serious trouble on either side in the shape of bunkers. It must be 220 yards (I speak from memory) from the tee to the center of the farthest green. It is slightly down hill, so that one can see exactly what there is to do. It will take a fine cleek shot or a difficult drive with a wooden club by a second class player, as the gulley which separates the two greens must be run through at the end of the shot. This is one of the only good cleek holes I have ever seen. There is a slight upward slope beyond the green so that there may be no fear of hitting the ball too hard---the difficulty is to get there."
....and in 1919 Oswald G. Kirkby wrote:
Perhaps the best hole is the ninth. I have never seen one like it. Roughly it must be over two hundred yards long.From the tee one looks away to find two greens, one beyond the other, with a hollow between them and bunkers looming on either side. It instantly impresses you as being a cleek shot. In fact, it is one of the few good cleek holes that I know. The roll of the land is slightly downhill, and that means an excellent cleek shot or a difficult drive by a second class player, as the gully which separates the two greens must be run through at the end of the shot. Beyond the green there is a slight upward slope, so that there may be no fear of hitting the ball hard; in fact, the difficulty is to get there. I consider it a splendid hole, because it calls for a perfect shot with the dreaded cleek
Both men called the front section a 'green', yet neither man even hints that the front section was used as a putting green. Their individual critiques are very similar, so much so that both men use the exact same wording to state "....the gulley which separates the two greens must be run through at the end of the shot", and they both note that "the difficulty is to get there", i.e, the back, where the putting green lay.
