high-tension wires to three of the big induction coils upon the table was, we believed, stored a power by which the Zeppelins could be successfully destroyed and brought to earth.
It was nearly dark when I opened the door of the shed situated opposite to where I had placed the box, and looked out to ascertain if anyone was about, as we wished for no prying eyes to witness our experiment.
I walked out, and around the building, but nobody was near. Then, when I returned to the door, I stood for a moment gazing away across the wide area of market-gardens to where, perhaps half a mile distant, stood a high flag-pole which had been erected for me a couple of years before, and which had, before the war, borne my wireless aerial.
The little white hut near by I had built, and until the outbreak of war, when Post Office engineers had come and seized my private station, I had spent many hours there each evening reading and transmitting messages.
The pole, in three sections, which in the falling darkness could only just be discerned, was about eighty feet in height and stayed by eight steel guys, each of which was in three sections connected together by green-glazed porcelain insulators, so that any leakage of electrical current could not go to earth. Affixed to the pole and protruding some two feet above it was a copper lightning-conductor with four points, an accessory which I had had put up recently for experimental purposes.
'Nobody's about,' I said to Teddy when I returned. 'Will you run the dynamo, if all is in order?'
