The beautiful grounds of the Quarry were black with thousands upon thousands of anxious spectators, and at a signal from the aeronaut Casteno and I, amidst loud cheers from the mob in the enclosure, took our places first in the car. There was room for a third passenger, and for a few seconds the Spaniard and I debated eagerly whether we should have Doris or the hunchback as the last party in the trio, and, if so, what line we ought to take with them lest they should suspect we were not those harmless members of a curious section of the public which we had given ourselves out to be. Unfortunately, as it happened, we were destined to have as travelling companion a total stranger to both of us. All at once we saw Doris beckon to the captain, and when he approached she introduced him to a tall venerable-looking figure with a long white beard. "This is the Professor Stephen Leopardi of the Meteorological Office, whom I mentioned to you," she said in her clear, ringing tones. "He is an old friend of my father and myself from London, but just now he happens to be staying near the Wrekin, and he is very anxious, if you will take him, to make the ascent with you. He is a man of science too, of considerable reputation, and any testimony he can bear to the uses of your invention must, in the natural course of things, be very valuable to you." "Quite so! Quite so!" rejoined both Captain Sparhawk and the hunchback, whose eyes gleamed with avarice at the prospect of getting so famous an expert to go with them and to speak up for them without a fee. "We shall really be only too delighted if the professor will make the sixth in our party--if he will consent to do so. There is a very nice seat vacant in the car we have reserved for independent passengers. Will he honour us by occupying that?" And with a good many flourishes and bows on both sides the scientist, to our profound disgust, was hoisted on to a seat next to Casteno and myself, thus cutting off for good all chance of our carrying on any private conversation or of giving each other any confidential hints. 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.
