was cause for vengeance, the proof should be written in blood and flame over all the wide dominions of the Tsar. Grief might come after, when there was time for it; but this was the hour of action, and a strange savage joy seemed to come with the knowledge that the safety of the woman he loved now depended mainly upon his own skill and daring.
Colston respected his silence, and waited until he spoke. When he did he was astonished at the difference that those few minutes had made in the young engineer. The dreamer and the enthusiast had become the man of action, prompt, stern, and decided. Colston had never before heard from his lips the voice in which he at length said to him —
“Where is this place? How far is it as the crow flies from here?”
“At a rough guess I should say about two thousand two hundred miles, almost due east, and rather less than two hundred miles on the other side of the Ourals.”
“Good! That will be twenty hours’ flight for us, or less if this south-west wind holds good.”
“What!” exclaimed Colston. “Twenty hours, did you say? You must surely be making some mistake. Don’t you mean forty hours? Think of the enormous distance. Why, even then we should have to travel over sixty miles an hour through the air.”
“My dear fellow, I don’t make mistakes where figures are concerned. The paradox of aërial navigation is ‘the greater the speed the less the resistance.’
“In virtue of that paradox I am able to tell you that the speed of the Ariel in moderate weather is a hundred and twenty miles an hour, and a hundred and twenty into two thousand two hundred goes eighteen times and one-third. This is Wednesday, and we have to be on the Asiatic frontier at daybreak on Friday. We shall start at dusk to-night, and you shall see tomorrow’s sun set over the Ourals.”
“That means from the eastern side of the range!”
“Of course. There will be no harm in being a few hours too soon. In case we may have a long cruise, I must have additional stores, and power-cylinders put on board. Come, you have not seen the Ariel yet.
“I have made several improvements on the model, as I expected to do when I came to the actual building of the ship, and, what is more important than that, I have immensely increased the motive power and economised space and weight at the same time. In fact, I don’t despair now of two hundred miles an hour before very long. Come!”
The engineer and the enthusiast had now come to the fore again, and the man and the lover had receded, put back, as it were, until the time for love, or perchance for sorrow, had come.
He put his arm through Colston’s, and led him up a hill-path and through a little gorge which opened into a deep valley, completely screened on all sides by heather-clad hills. Sprinkled about the bottom of this valley were a few wooden dwelling-houses and workshops, and in the centre was a huge shed, or rather an enclosure now, for its roof had been taken off.
In this lay, like a ship in a graving-dock, a long, narrow, grey-painted vessel almost exactly like a sea-going ship, save for the fact that she had no funnel, and that her three masts, instead of yards, each carried a horizontal fan-wheel, while from each of her sides projected, level with the deck, a plane twice the width of the deck and nearly as long as the vessel herself.
They entered the enclosure and walked round the hull. This was seventy feet long and twelve wide amidships, and save for size it was the exact counterpart of the model already described.
As soon as he had taken Colston round the hull, and roughly explained its principal features, reserving more detailed description and the inspection of the interior for the voyage, he gave the necessary orders for preparing for a lengthy journey, and the two went on board the Lurline to dinner, which Colston had deferred in order to eat it in Arnold’s company.
After dinner they carefully discussed the situation in order that every possible accident might be foreseen, argued the pros and cons of the venture in all their bearings, and even went so far as to plan the vengeance they would take should, by any chance, the rescue fail or come too late.
The instructions, signed by Natas himself, were very precise on certain essential points, and in their broad outlines, but, like all wisely planned instructions to such men as these, they left ample margin for individual initiative in case of emergency.
Some of the stores of the Lurline had to be transferred to the Ariel, and these were taken ashore after dinner, and at the same time Colston made his first inspection of the interior of the air-ship, under the guidance of her creator. What struck him most at first sight was the apparent inadequacy of the machinery to the attainment of the tremendous speed at which Arnold had promised they should travel.
There were four somewhat insignificant-looking engines in all. Of these, one drove the stern propeller, one the side propellers, and two the fan-wheels on the masts. He learnt as soon as the voyage began, that, by a very simple switch arrangement, the power of the whole four engines could be concentrated on the propellers; for, once in the air, the lifting wheels were dispensed with and lowered on deck, and the ship was entirely sustained by the pressure of the air under her planes.
There was not an ounce of superfluous wood or metal about the beautifully constructed craft, but for all that she was complete in every detail, and the accommodation she had for crew and passengers was perfectly comfortable, and in some respects cosy in the extreme. Forward there was a spacious cabin with berths for six men, and aft there were separate cabins for six people, and a central saloon for common use.
On deck there were three structures, a sort of little conning tower forward, a wheel-house aft, and a deck saloon amidships. All these were, of course, so constructed as to offer the least possible resistance to the wind, or rather the current created by the vessel herself when flying through the air at a speed greater than that of the hurricane itself.
All were closely windowed with toughened glass, for it is hardly necessary to say that, but for such a protection, every one who appeared above the level of the deck would be almost instantly suffocated, if not whirled overboard, by the rush of air when the ship was going at full speed. Her armament consisted of four long, slender cannon, two pointing over the bows, and two over the stem.
The crew that Arnold had chosen for the voyage consisted, curiously enough, of men belonging to the four nationalities which would be principally concerned in the Titanic struggle which a few weeks would now see raging over Europe. Their names were Andrew Smith, Englishman, and coxswain; Ivan Petrovitch, Russian; Franz Meyer, German; and Jean Guichard, Frenchman. Diverse as they were, there never were four better workers, or four better friends.
They had no country but the world, and no law save those which governed their Brotherhood. They conversed in assorted but perfectly intelligible English, for the very simple reason that Mr. Andrew Smith consistently refused to attempt even the rudiments of any other tongue.
While the stores were being put on board, Arnold made a careful examination of every part of the machinery, and then of the whole vessel, in order to assure himself that everything was in perfect order. This done, he gave his final instructions to those of the little community who were left behind to await the arrival of the steamer, and as the sun sank behind the western ridges of the island, he went on board the Ariel with Colston, took his place at the wheel, and ordered the fan-wheels to be set in motion.
Colston was standing by the open door of the wheel-house as Arnold communicated his order to the engine-room by pressing an electric button, one of four in a little square of mahogany in front of the wheel.
There was no
