I went down to London and purchased a common ear-trumpet. My own ear was exceedingly acute, and to my great delight I found that, with the aid of the trumpet just as it was, I could distinguish sounds at a much greater distance, and those nearer were magnified in power. I had only to improve upon this instrument; careful study, careful work, careful experiment, and my hopes would undoubtedly be realized. Back to my old room in the college I went with a complete set of tools. So days and weeks I shut myself in, and every day and every week brought nothing but disappointment. The instrument seemed only to diminish sound rather than increase it, yet still I worked on and vowed I would not grow discouraged. Hour after hour I sat, looking out of my narrow window. The fields of barley and waving oats had been reaped, the wheat too had ripened and gone, but I did not notice. I sprang up with a joyful exclamation—Strange never to have thought of it before! Perhaps I had not spent my time in vain, after all. How could I expect to test my instrument in this close room with only that little window? It should be removed from immediate noises, high up in the open air, where there would be no obstructions. I would never succeed here—but where should I go? It must be some place in which I would never be liable to interruption, for my first object was to be shielded and work in secret. I scoured the neighborhood for an appropriate spot without success, when it occurred to me that I had heard some one say the old gray church was shut up. This church was situated just beyond the suburbs of the town. It was built of rough stone, mottled and stained by unknown years. The high, square tower, covered by thick vines that clung and crept round its base, was the most venerable monument among all the slabs and tombs where it stood sentinel. Only graves deserted and uncared for by the living kept it company. People said the place was too damp for use, and talked of rebuilding, but it had never been done. Now if I could gain access to the tower, that was the very place for my purpose. I found the door securely fastened, and walked round and round without discovering any way of entrance; but I made up my mind, if it were possible to get inside of that church I would do it, and without the help of keys. The high windows were not to be thought of; but in the rear of the building, lower down, where the fuel had probably been kept, there was a narrow opening which was boarded across. With very little difficulty I knocked out the planks and crept through. It was a cellar, and, as I had anticipated, the coal receptacle. After feeling about, I found a few rough steps which led to a door that was unlocked and communicated with the passage back of the vestry-room.
