"You will have to wrap up well," said the Captain. "It's jolly cold up there. It looks rather misty, and that will make it all the worse. Now then, all aboard."

Up I scrambled, or rather wriggled, between a network of wire stays, and taking my seat the camera was handed to me. I fastened it on one side of the gun-mounting and fixed a Lewis gun on the other, making sure I had spare boxes of film ready, and spare drums of ammunition. I then fastened the broad web belt round my waist, and fixed on my goggles.

I was ready for the ascent.

My companion was in his seat, and the machine was wheeled into position for starting. The mechanics were turning the propeller round to suck the gas into the many cylinders, to facilitate easier starting.

"All ready," shouted the Captain. "Right away, contact, let her go." And with a jerk the motor started.

The whirl of the huge blades developed into a deafening roar. The machine vibrated horribly. I clung to my camera, holding it tight to the socket. I knew that once in the air the shake would be reduced to a minimum. Faster and faster whirled the propeller as the Captain opened the throttle. How sweet and perfect was the hum of the giant motor. Not the slightest sound of a misfire. Being an ardent motorist, I could tell that the engine was in perfect tune. The Captain leaned over and shouted to me through the roar to fasten the telephone receiver against my ear under my leather cap.

"That," said he, pointing to a mouthpiece attached to a small rubber tube, "is the transmitter. If you want to give me any instructions shout into that. I shall hear you. All fit?" he asked.

I nodded my head. He took his seat, and opened the throttle. The engine leapt into new life. The roar was deafening. The whirring blades flung the air back into my face, cutting it as if with a whip. He dropped his arm. The men drew away the chocks from the wheels, and amid shouts of "Good luck!" from the officers present, the machine sprang forward like a greyhound, bounding over the grass, until at last it rose like a gigantic bird into the air.

The earth gradually drew away. Higher and higher we rose, and began to circle round and round to gain height.

"We will get up to three thousand feet before we strike towards the coast," he shouted through the telephone.
