With old Theed as sentry, we worked away in the farmyard, the doors of which were carefully closed, assembling the machine. That work took three days, though we all strove with a will, leaving Mulliner to act as housekeeper and prepare our meals.

Every day Theed’s son took the farmer’s cycle and went to get us a paper at Forest Row Station on the line between Tunbridge Wells and Horsham, that being the only connexion we held with the world outside. The good farmer I had paid handsomely, and had frankly told him that we were making some secret experiments with a new aeroplane against the Germans, whereupon he, as a good Englishman, had promised to hold his tongue.

That week passed rapidly—a week of arduous work, of intense anxiety and excitement. Sometimes a part would not fit, or was missing, and then our spirits would instantly flag. Still, after much eagerness—and sometimes a few bad words, sotto voce, of course—we gradually got the machine into readiness, and began the engine-test.

So powerful were those twin engines, with their wide throttle range, that their roar could be heard miles away, for I had not been able to silence them. Nevertheless, nowadays, country people are happily so used to hearing the rhythmic throb of aeroplane engines, that they scarcely take notice of it. Mine, however, were unusually fierce, especially when both were working, one for the propeller, and the other either for the searchlight or the directive sparking apparatus.

They had both been run “upon the bench” for many hours, of course, and passed as perfect by the makers. Yet a pilot never likes to trust himself upon something he has not tested with his own hands.

Each one of us had his or her own work, and each one of us worked with a true spirit of patriotism. I had argued that if the Anti-Aircraft Service were unable to bring down Zeppelins, then I, as a private individual and a pilot who had had some experience in the air, was ready to risk my own life in the attempt. And in this Teddy was whole-heartedly with me.

Naturally, Roseye often grew apprehensive. It was because of that she made me repeat many times the promise I had given her—that she should make the first flight with me in the newly-constructed machine.

Each day Teddy and I, aided by young Theed, worked testing, tightening strainers, seeing to pins and washers, adjusting bolts and other things. And at evening, while the Theeds and Mulliner gossiped in the kitchen, we three made ourselves comfortable before the great log fire in the farmer’s best room, and sometimes passed the time with cards, a well-thumbed pack of which Roseye had discovered in a drawer.

One evening we had played cards and Teddy had wished us good night, taken his candle and ascended the narrow creaky stairs, worn hollow by the tread of generations of farmers.

“Claude,” exclaimed my love, when we were alone, “I feel so very worried over you! I know how keen you are to act your part in this war, and to put your theory to the test. But is it really wise? Remember that you are going to risk your life. The creation of that electric wave, when in the air, may re-act upon your own engines and seize them—or it may create a spark across your own petrol-tank. In that case you would be blown up in mid-air!”
