Mark:
I have all the articles at my office. There were not that many entries, as I remember ... a couple dozen, or something like that.
They did publish three runners-up in a subsequent article, plus an entry from Tom Simpson which was not considered. It is a much under-publicized fact that Macdonald and Raynor used Simpson's hole, plus one or two of the runners-up, as models for holes at Lido, too ... in fact, their version of Simpson's hole was far more faithful to the drawing than the prize-winner.
I'm not sure why the competition was in "Country Life". That magazine had also published the "Best Hole Discussion" which prompted Macdonald to start seriously looking for a site for the National Golf Links, so maybe Macdonald had a relationship with them. Or maybe he was just at odds with the few American golf magazines at the time. [Actually, I'm not even sure if there WERE any American golf magazines in 1914 ... I don't remember if The American Golfer or Golf Illustrated go that far back.]
