week of June. I sat up on the coping of the bridge admiring my frail canvas shoes which I had diligently pipeclayed overnight and watching the docile horses pulling a tramload of business people up the hill. All the branches of the tall trees which lined the mall were gay with little light green leaves and the sunlight slanted through them on to the water. The granite stone of the bridge was beginning to be warm and I began to pat it with my hands in time to an air in my head. I was very happy.

When I had been sitting there for five or ten minutes I saw Mahony’s grey suit approaching. He came up the hill, smiling, and clambered up beside me on the bridge. While we were waiting he brought out the catapult which bulged from his inner pocket and explained some improvements which he had made in it.
