I've quoted this on here before but I feel it could be relevant:
"The question of bunkers is a big one and the very best school for study we have found is along the seacoast among the dunes. Here one may study the different formations and obtain many ideas for bunkers. We have tried to make them natural and fit them into the landscape. The criticism had been made that we have made them too easy, that the banks are too sloping and that a man may often play a mid-iron shot out of the bunker where he should be forced to use a niblick. This opens a pretty big subject and we know that the tendency is to make bunkers more difficult. In the bunkers abroad on the seaside courses, the majority of them were formed by nature and the slopes are easy; the only exception being where on account of the shifting sand, they have been forced to put in railroad ties or similar substance to keep the same from blowing. This had made a perfectly straight wall but was not done with the intention of making it difficult to get out but merely to retain the bunker as it exists. If we make the banks of every bunker so steep that the very best player is forced to use a niblick to get out and the only hope he has when he gets in is to be able to get his ball on the fairway again, why should we not make a rule as we have at present with water hazards, when a man may, if he so desires, drop back with the loss of a stroke. I thoroughly believe that for the good of Golf, that we should not make our bunkers so difficult, that there is no choice left in playing out of them and that the best and worst must use a niblick.”
