"During the last twenty years I have studied the course from every angle and listened with an attentive ear; consequently very few of the holes have not been altered, although most of the changes have been slight. Only this year I have distinctly altered the fourteenth and seventeenth, making these holes, which were both rather short drive and pitch holes, some thirty yards longer and bunkering them more closely. On many of the hole I have, at different times, built entirely new putting greens, lengthening some and shortening others. I am not confident the course is perfect and beyond criticism today."
