At last we emerged once more into the cold bright night. The atmosphere of the cloud had chilled us both to the bone, but as we emerged the long white ray fell quickly upon us. Then I swerved, so as to exhibit to the naval watchers the rings upon my planes and decreased my speed to show that I had neither desire nor intention to escape. Indeed, I hovered there for a few moments in order to let them have good sight of me. This satisfied them, and once again the long white ray was shut off. In the increased light I found that road which most motorists know so well, the steep and often winding way which runs near Beachy Head down to Friston and on to Seaford. Then, flying over Newhaven, I kept on to Rottingdean and headed for the scattered and ill-obscured lights of Brighton. Flying at 3,000 feet I passed over the central station at Brighton, striking north to Lewes, with my eyes constantly upon my watch. From Lewes I followed the right-hand line of railway which I saw, by the map, would lead me past Barcombe to Uckfield. And with my engine running well I again, on gaining Buxted, struck due east in search of another line of railway which would lead me to Mayfield. Here, I had some difficulty. I found a winding river, and believing it to be the Rother, took my bearings by it. Ten minutes later I found I had made an error, and had to return to Buxted and take fresh bearings, which eventually led me once again back over Mayfield. An hour had passed, and I now again began to search for Teddy. By the bearings I had taken before, I soon picked up the spire of Stockhurst and, descending to about 500 feet, again circled around it. I had only made one circuit when we both saw Teddy's flashes, and then we knew that all was in readiness. _The moment of our great experiment had come_! Roseye, who had taken careful instructions beforehand, prepared to manipulate the levers, while I flew the machine. To judge distance in the darkness is always extremely difficult, especially when one is flying an aeroplane. Nevertheless, I had already made calculations and, assisted by my previous experiences of night-flying, began the trial. I had been travelling at sixty miles an hour for the past few minutes, but I now slowed up and, dropping still another hundred feet or so, circled out until I gauged that I was about five hundred yards distant from the tall, thin steeple. While I pointed the nose of the machine in the direction of the church, Roseye set the secondary engine and dynamo at work. Then I drew over the little red-painted switch on the box close at my hand ere Roseye was aware of my intention. I left it there for a full minute, directing the invisible wave of electricity upon the lightning-conductor of the church. Then I released it, and wondered what result the watchful Teddy had observed.
