At length the light began to fade, and for that day their experiments were over. In token of their conclusion twice Stella rang the electric warning bell which was attached to the aerophone, and in some mysterious manner caused the bell of its twin instrument to ring also. Then she packed the apparatus in its box, for, with its batteries, it was too heavy and too delicate to be carried conveniently, locking it up, and left the church, which she also locked behind her. Outside it was still snowing fast, but softly, for the wind had dropped, and a sharp frost was setting in, causing the fallen snow to scrunch beneath her feet. About half-way along the bleak line of deserted cliff which stretched from the Dead Church to the first houses of Monksland, she saw the figure of a man walking swiftly towards her, and knew from the bent head and broad, slightly stooping shoulders that it was Morris coming to escort her home. Presently they met.

“Why did you not wait for me?” he asked in an irritated voice, “I told you I was coming, and you know that I do not like you to be tramping about these lonely cliffs at this hour.”

“It is very kind of you,” she answered, smiling that slow, soft smile which was characteristic of her when she was pleased, a smile that seemed to be born in her beautiful eyes and thence to irradiate her whole face; “but it was growing dreary and cold there, so I thought that I would start.”

“Yes,” he answered, “I forgot, and, what is more, it is very selfish of me to keep you cooped up in such a place upon a winter’s day. Enthusiasm makes one forget everything.”

“At least without it we should do nothing; besides, please do not pity me, for I have never been happier in my life.”

“I am most grateful,” he said earnestly. “I don’t know what I should have done without you through this critical time, or what I shall——” and he stopped.

“It went beautifully to-day, didn’t it?” she broke in, as though she had not heard his words.

“Yes,” he answered, “beyond all expectations. We must experiment over a greater distance, and then if the thing still works I shall be able to speak with my critics in the gate. You know I have kept everything as dark as possible up to the present, for it is foolish to talk first and fail afterwards. I prefer to succeed first and talk afterwards.”

“What a triumph it will be!” said Stella. “All those clever scientists will arrive prepared to mock, then think they are taken in, and at last go away astonished to write columns upon columns in the papers.”

“And after that?” queried Morris.
