Jamie,
Yes, I was actually thinking of the bunker on the 4th at Sandwich. My mistake
I've just dug out Darwin's description of the ninth...
"a hole of which men used to speak with the same reverential awe with which they alluded to the 'Maiden' at Sandwich. Certainly that bunker in front of the green is sufficiently desperate, and to be compelled to approach the hole with a brassey may well inspire fear, but a good drive on a calm day should leave us little more than a firm half iron shot to play, and then we can afford to treat the bunker almost with contempt."
and later...
"we may be just short with our second - a matter of six inches perhaps - and we shall be battering the bunkers unyielding face till our card is shattered and wrecked."
There is also one of Roundtree's paintings of the 9th green and 10th tee, which looks to be the same as we play today? So Darwin's comparison with Sandwich's Maiden was in the sense of the fear felt getting past said obstacle, rather than a direct physical comparison.
Tom's historic photo above and Roundtree's painting indicate that the 9th back in CBM's day and the current one, are one and the same hole? It seems to me that what is now a silted up occasional tidal area, could perhaps of been a more sandy (occasionally tidal?)area, that played as a bunkerl?
Interestingly, Darwin doesn't mention the short 5th (now 4th) at all?
Cheers,
James
