Here is Travis in 1908 recounting how he had a ball stop at the very apex of one of the mounds, and then holed the next shot. He also offers a good description of the hole.
(Jon, note he describes the mounds as on "either side of the green.")
Playing the twelfth hole at Garden City the other day, I put my tee shot in the bunker to the right—where it usually goes—and in playing out, lodged the ball on the very apex of a conical mound about three feet high, which had stymied my approach. How the ball managed to stay there is an absolute mystery. I suppose I could try it a million times again, from any distance, and with any club, without getting it to stay right on the very pinnacle. And wonders did not cease there! From the top of that mound I holed the ball with a mid-iron! The hole is one hundred and eighty-six yards from the middle of the tee to the middle of the green. The tee is some twenty-two yards in depth, the theory of the hole being that a full shot is demanded, involving a carry of at least one hundred and sixty yards, the tee-plates being moved backward or forward, according to the wind. It is a very difficult hole. On either side of the green are large mounds, beautifully turfed, some five feet at the highest point, tapering down to nothing. Over these mounds a ball may be putted or pitched. Immediately in front, about ten yards from the edge of the green, is a very deep bunker with big sand piles on either side and a sand bunker semi-circling the green about 20 yards equidistant from the edge of the green. During the last Amateur Championship, this hole came in for a great deal of criticism, both favorable and otherwise, and was variously dubbed, the Camel; the Dromedary; the Goat; the Sea Serpent; the Sacred Cow; the Hog's Back; the Razor Back; the Gate of Hell; the Humps; the Hummocks; the Hillocks; Travis's trap; and Travis's travesty. As somebody very truly observed, a hole which lends itself so easily to so many names must have undoubted merits. It is one of the hardest holes I know of, anywhere.
