That brought the great Dicky to his senses. He sat up on an elbow, still blinking at Alec with half-open eyes. Then those sharp orbs of his opened widely, the light of full understanding returned to them, and in an instant he was out of bed.
"My word, but I've been dreaming the whole affair over again, and couldn't think it could be true. And it's real? Eh? Actually a fact that I'm on board an airship high in the air. How high did you say?"
Alec made no answer. He stepped across the carpeted floor of this roomy cabin, with its milk-white walls and furniture, and its pictures secured to those same walls by tiny cleats of transparent material, and turning back some hangings exposed a window three times the size of an ordinary porthole, and provided with a pane of what one would have imagined was glass. But it bent with the force of the wind. Half open, the frame projected into the room at an angle to Dick, and glancing at it he caught a reflection of the sun, now bright, and a second later blurred as the pane bent and the surface was altered. The simple fact brought him bounding after Alec. He ran his fingers over both sides of the pane, bent the material backward and forward, and then tapped it with his knuckles. That done he suddenly gazed upward, only to find himself disappointed.
"You don't expect to have transparent roofs to your cabins too, do you?" laughed Alec. "A fellow couldn't undress without half the crew seeing him. No, the ceilings of the dressing-rooms, cabins, and so forth are made opaque. But this window gives you a good idea of the stuff of which the ship's made. Now, take a squint below."
Dick did as he was bidden, and instantly clutched tight to the frame of the window. For down below, down a terrible distance, was a smooth, oily surface which he guessed was the ocean. And on it were a number of minute dots at irregular intervals, while away to the right was a blurred patch of white, which might be land or anything else. The sight made him absolutely giddy. A glance away to his right showed him the under-surface of this enormous ship, transparent, it is true, but of a bluish-grey colour owing to the shadows cast upon it. It was immense. It stretched away from him in an easily-curving line till it was lost in the distance. And beneath it there was nothing, nothing but thin elusive air, and far, far below that muddy ocean.
"Jingo!" he gasped.
Alec grinned. "Makes a chap feel queer at first," he said. "But, as I've told you before, it's as safe as houses. Here, tumble into a tub. It'll buck you up, and when you've been on top with me and had a general look round you'll feel as right as a trivet. Shave?"
"Eh?" asked Dick.
"Do you shave?"
