It seems like the belief will never die that Macdonald's concept of copying holes from the other side only meant he copied entire holes and fairly exactly. In some cases he probably did to that but seemingly in many other cases he simply used ideas from other holes abroad.
Listen to his own words on this:
"I labored four years to that end. In 1904 I again made a study of foreign courses, reflecting on the "whys" and wherefore." In 1906, after four months in Europe, I completed my research studies and brought home with me surveyors' maps of the more famous holes; Alps, Redan, Eden, and the Road hole, also some twenty or thirty sketches, personally drawn, of holes embodying distinctive features, which in themselves seemed misplaced, but could be utilized to harmonize with a certain character of undulating ground and lay the foundation for an ideal hole."
The green type of the Biarrtz is probably the latter, and it seems to me the green of NB's 16th is a very good candidate for where he got one of his ideas to copy.
