The Modern course was proposed in 1937/38 and sat mostly on unused land between the sandhills and the sea, which had gradually appeared over the years (north of Jubilee and New course), it also borrowed the best land from the New course and the Jubilee. Its regular yardage was 6400, but it could be stretched to 7200 on championship days. Darwin was major proponent of the plan and was very impressed with H&C's design. Darwin quoting Campbell:
"....Just visualise its position. Twelve of the eighteen holes will lie between the sand-hills, high and low, and the sea; another four on the wildest part of the New course, and the remaining two on the best part of the Jubilee course, looking across the Old course to the Strathtyrum Woods. And twelve of the eighteen greens will be in full view of the sea. What other links can boast as much?"
The entire article including the routing will be in the next Australian 'Golf Architecture' magazine.
