A few minutes later Doris and the hunchback entered the adjacent car. Captain Sparhawk shook hands warmly with some of his more prominent supporters and friends on the committee and followed them, and the next moment he blew a shrill call on a small whistle attached to the motor, close to which he had taken up his position, ready to set all the machinery at work.

There was a loud crash of cannon, an ear-splitting salvo of cheers as one by one the guide-ropes slipped out of their blocks, and finally the air-ship “Doris” rose free from her moorings and went sailing like a bird across the river Severn in the direction of Welshpool.

At first the sensation was delightful. The earth and its people and features dropped away from us, until we seemed to have risen out of the hollow of a basin. There was no sense of ascent at all. The world slipped away from us, and not we away from the world. One by one the sounds died out, until at last we could only catch the hoarse barking of some sheep-dogs which must have seen us with those keen eyes of theirs and thought mischief was astir. Clouds, too, began to rush swiftly towards us, and soon we found ourselves enveloped in a soft, clinging, whitish mist, which blotted out all sight of the earth we had left behind us.

We were now being carried upward with a terrific force, and insensibly all of us turned our eyes towards Captain Sparhawk to see how he was going to acquit himself and his machine now the time of real trial had come. After all, any balloon could rise like this had done. Indeed, all balloons had been able to accomplish as much since the days of the Brothers Montgolfier. It was on the steering—directing—descent that the fame of the “Doris” and all modern flying machines had to rest. How would the vessel behave in a wild upward dash like ours?

Alas! we had not long to wait for an answer.

All at once we saw Captain Sparhawk stagger and throw up his arms. The wind had blown his coat, which he had carelessly left unfastened, against the motor, and the petroleum ignition had set the dry woollen material on fire. In vain he tried to extinguish the flames. They spread with hideous rapidity, and at last, frantic with pain, he scrambled on to the framework, and dashed headlong to the earth, a seething mass of fire.

For a moment, I believe, all our hearts stood still with terror.

Freed, too, from the burden of Captain Sparhawk’s weight, the air-ship shot upward at a most amazing rate of speed. At first it gave two great violent lurches, as though the loss of that twelve or fourteen stone of ballast would send it heeling over, with its cars at a crazy angle ’twixt earth and heaven, but, luckily, in our consternation we all made various movements that served to right the vessel, and later we found ourselves safe, at all events for the moment, but perfectly helpless. By this time, too, there was not a trace of the world to be seen. We were simply surrounded with clouds, which seethed about us in white, clinging vapour and wrapped themselves about our clothes and faces as though we had been overtaken in a mist on some Scottish moor.

“Something will have to be done,” said the professor sternly, turning suddenly to Casteno and myself, his sole travelling companions in that car. “We can expect no assistance from that old hunchback or that girl, Miss Napier, in the other compartment. Do either of you gentlemen understand anything about air-ships?” And he gave a quick, scrutinising gaze at our uniforms, as though he could find thereon some badge which showed we belonged to the ballooning section of the Royal Engineers.

“We know nothing whatever,” replied José quietly, stamping up and down to keep his feet warm. “We have come, for pleasure we thought it, and here is the result.”
