But who knew such rules might still be relevant today?
At one Australian course, the locals are interested, you might say, in the possibility that an unexploded Japanese bomb lies beneath one of the fairways.
The course is Royal Sydney Golf Club. The bomb is a leftover from a shelling of Sydney Harbor by a Japanese submarine in 1942.
Two historians investigating that attack believe at least one of the bombs is unaccounted for, and lies under the ground of the No. 8 fairway at Royal Sydney.
The club issued a statement to the effect that there was really nothing to worry about:
The club notified the Defence Department's explosives ordnance division, which advised no action was necessary at this stage.
"The club has sought expert advice in this matter," the statement read.
"If the club is advised that underground exploration should be undertaken, the club will act immediately."
But if I'm ever playing Royal Sydney, I'll be careful not to take too deep a divot on the eighth hole.
