We've had many discussions in the past on this green and whether it is the inspiration for Macdonald's Biarritz green. I've always argued that it couldn't have, because Bernard Darwin didn't describe the green as interesting in his 1908 volume.
Well, I just happened to look back in Darwin's book today, and this is what he said about the 16th at North Berwick:
"At the sixteenth we cross the wall once more, and may hope to reach in two shots the 'Gate' hole, standing on another plateau -- an exceedingly dimunitive one, by the way -- close to the high road.
So, the green was only on one of the two plateaux back at the turn of the century when Macdonald would have become familiar with it.
Also, for whomever it was who was talking about the 17th hole the other day ...
"In our second shot we shall have to decide whether or not to carry a bunker that stretches across our path, and then comes the crucial shot, the approach on to that dreadful green that slopes right away from us to the sea -- without the ghost of a charitable back wall. It is so frightening that we are strongly tempted to approach it on the instalment system, and it is really wonderful how many instalments may be necessary, as with limbs palsied with terror, we push and poke the ball over that treacherous and slippery surface."
I have always taken this to mean that the flag for #17 was cut where the flag for #1 is cut today. Darwin's description of the first hole refers to the "double green of Point Garry".
