The air grew steadily fresher, until, after I had gone about two hundred yards, I reached a point where the wind seemed to beat down on me from above. I put up my hands and found two openings about two yards apart, through which the air sucked steadily. I moved out of the current with a chuckle in my throat and a grin on my face. I had passed under the gate in the school-wall, and I knew now why the piers that held it had been built so high,—they were hollow and were the means of sending fresh air into the tunnel.

I had traversed about twenty yards more when I felt a slight vibration accompanied by a muffled roar, and almost immediately came to a short wooden stair that marked the end of the passage. I had no means of judging directions, but I assumed I was somewhere near the chapel in the school-grounds.

I climbed the steps, noting still the vibration, and found a door that yielded readily to pressure. In a moment I stood blinking, lantern in hand, in a well-lighted, floored room. Overhead the tumult and thunder of an organ explained the tremor and roar I had heard below. I was in the crypt of St. Agatha’s chapel. The inside of the door by which I had entered was a part of the wainscoting of the room, and the opening was wholly covered with a map of the Holy Land.

In my absorption I had lost the sense of time, and I was amazed to find that it was five o’clock, but I resolved to go into the chapel before going home.

The way up was clear enough, and I was soon in the vestibule. I opened the door, expecting to find a service in progress; but the little church was empty save where, at the right of the chancel, an organist was filling the church with the notes of a triumphant march. Cap in hand I stole forward and sank down in one of the pews.

A lamp over the organ keyboard gave the only light in the chapel, and made an aureole about her head,—about the uncovered head of Olivia Gladys Armstrong! I smiled as I recognized her and smiled, too, as I remembered her name. But the joy she brought to the music, the happiness in her face as she raised it in the minor harmonies, her isolation, marked by the little isle of light against the dark background of the choir,— these things touched and moved me, and I bent forward, my arms upon the pew in front of me, watching and listening with a kind of awed wonder. Here was a refuge of peace and lulling harmony after the disturbed life at Glenarm, and I yielded myself to its solace with an inclination my life had rarely known.
