The fine old warden of the keys told me he couldn’t take me over the place without a permit from the architect of the city, so I went to the architect’s home, only to find him out. When I returned to the cathedral, disappointed, the old man said that if I would return at nine in the morning he would take me through. At nine in the morning we started. We started up the tower and branched off at one of the little doors into the clerestory that led all around the inside of the church nave. Here we saw the organ. From here we mounted a dark, uneven passage within the walls which brought us out to the lowest stage of the roof, where the bases of the flying buttresses rest. We traversed the gutter, which was really a promenade, to the choir end of the cathedral. Here again we wound up a circular stairs within a great buttress pier and came out on the little narrow stair cut right up the flying buttress span to the main roof. Here we entered another little door, and found ourselves right in the garret over the altar. Under my feet was the great span of the main vault, and over my head the original joinery of the great peaked roof. In the darkness of the garret we passed great old windlasses for lowering the huge candelabra which hung in the nave. We traversed the garret to where through a little door a shaky scaffolding led over a deep pit to the tower of the prison. Here, again, was a huge chamber lighted by narrow slits in twenty-foot walls. We descended again and at every landing was a narrow cell which came to a point in a small slit which admitted light and indentation in the stone on which to sit. It was uncanny. It was a relief to come again to the day, where the bright sunlight played upon gargoyles and grotesques hiding in the carved stone. Such a feast of the imagination! I could sit down now and write a novel laid in the confines of that pile. Then a fellow whom I met and I went down and explored the crypt. There were unlit shrines and unaired vaults which ended by a wall one could not see over, and the air was cool and damp and so bad a match would not burn. We went out to breathe fresh air, and dream in the sun. YOUR SON. _Ecole d’Aviation, Tours, August 28, 1917._ DEAR MOTHER:
