That night at eleven I met Simson at the gate. He had come by train, and I let him in gently myself. I had been so much absorbed in the coming experiment that I passed the ruins in going to meet him, almost without thought, if you can understand that. I had my lantern; and he showed me a coil of taper which he had ready for use. “There is nothing like light,” he said, in his scoffing tone. It was a very still night, scarcely a sound, but not so dark. We could keep the path without difficulty as we went along. As we approached the spot we could hear a low moaning, broken occasionally by a bitter cry. “Perhaps that is your voice,” said the Doctor; “I thought it must be something of the kind. That’s a poor brute caught in some of these infernal traps of yours; you’ll find it among the bushes somewhere.” I said nothing. I felt no particular fear, but a triumphant satisfaction in what was to follow. I led him to the spot where Bagley and I had stood on the previous night. All was silent as a winter night could be,--so silent that we heard far off the sound of the horses in the stables, the shutting of a window at the house. Simson lighted his taper and went peering about, poking into all the corners. We looked like two conspirators lying in wait for some unfortunate traveller; but not a sound broke the quiet. The moaning had stopped before we came up; a star or two shone over us in the sky, looking down as if surprised at our strange proceedings. Dr. Simson did nothing but utter subdued laughs under his breath. “I thought as much,” he said. “It is just the same with tables and all other kinds of ghostly apparatus; a sceptic’s presence stops everything. When I am present nothing ever comes off. How long do you think it will be necessary to stay here? Oh, I don’t complain; only when _you_ are satisfied, _I_ am--quite.”
