When I was ten, I started out playing golf on a 3 hole sand greens golf course. First hole was 175 yards from a slightly elevated tee and the "fairway" crossed hole #3. The tee ball had to cross a railroad track. Once I saw a tee ball come back off the rails and pass directly over the head of the would be golfer. Without searching for the ball he put his club back in his bag and his bag back in his truck and sped away from the "course." Apparently he subscribed to the theory that when the golf course starts shooting back it's time to leave.
Hole #2 was 135 yards and crossed the #3 "fairway".
Hole #3 was 125 yards and crossed both #1 and #2.
As was stated above. oil was used to compact the sand, but for most of the year there was almost no sand on the greens so they were actually just oil soaked dirt.
Not only can you not maintain contours, you can't stop a ball on them. Everything was the ground game at Hastings WV in 1950. Come to think of it, there was hardly any grass on the course. It might be fair to describe the layout as dirt course with sand greens.
