It was in this craft that the seekers after the diamond makers proposed undertaking the trip. Mr. Damon came on from his home in Waterfield about two days before the date set to leave, and Mr. Jenks, had, three days before this, taken up his abode at the Swift home. Mr. Parker, as has been stated, was already there, and he had put in his time making a number of scientific observations, though he had made no more predictions.
Nothing more had been seen of the mysterious man who had warned Tom, and the young inventor and Mr. Jenks began to hope that they had thrown their enemies off the track.
"Though I don"t imagine they"ll give up altogether," said Mr. Jenks.
"They"re too desperate for that. We"ll have trouble with them yet."
"Well, it can"t be helped," decided Tom. "We"ll try and be ready for it, when it comes," and then, dismissing the matter from his mind, he busied himself about the airship.
The food and supplies had all been put aboard, and they expected to start the next morning. In order to make sure that any stones which they might succeed in getting from the diamond makers were real gems, a set of testing apparatus was taken along. Mr. Parker had had some experience in this line, and, in spite of the fact that he might make direful predictions, Tom was rather glad, after all, that the scientist was going to accompany them.
"But what is worrying me," said Mr. Damon, "is what we are going to do after we get to Phantom Mountain. What are your plans, Mr. Jenks? Will you go in, and demand your share of the diamond-making business?"
"I have a right to it, as I invested a large sum in it, and I am ent.i.tled to more than a half-share. But, of course, I can"t say what I"ll do until I get there. We may have to act very secretly."
"I"m inclined to think we will," said Tom. "My plan would be to gain access to the cave, if possible, and watch them at work. We might be able to discover the secret of making diamonds, and, after all, that"s what you want, isn"t it, Mr. Jenks?"
"Yes, I paid my money for the secret, and I ought to have it. If I can get it quietly, so much the better. If not, I"ll fight for my rights!"
and he looked very determined.
"Bless my powder horn!" cried Mr. Damon. "That"s the way to talk! And so we"re to go cruising about in the air, looking for a mountain shaped like a man"s head."
"That"s it," agreed Mr. Jenks, "and when we find it we will be near Phantom Mountain, and the diamond makers."
The final details were completed that night. The last of the supplies had been put aboard, the larder was well stocked, the diamond testing apparatus was stored safely away, and all that remained was for the adventurers to board the Red Cloud in the morning, and soar away.
That night Tom was uneasy. Several times he got up, and looked toward the shed where the airship was stored. He could not rid himself of the idea that the men to whose interest it was that the diamond-making secret remain undiscovered, might attempt to wreck the airship before the start. Consequently both Eradicate Sampson and Engineer Jackson were on guard. Tom looked from his window, to the shed where the Red Cloud was housed. He saw nothing to cause him any uneasiness.
"I guess I"m just nervous," he mused. "But, all the same, I"ll be glad when we"ve started."
They were all up early the next morning, Mr. Damon beginning the day by blessing the sunrise, and many other things that struck his fancy.
The airship was wheeled out of the shed, and Tom gave her a final inspection.
"It"s all right," he declared. "All aboard!"
"Now, do be careful," begged Mr. Swift. "Don"t take too many chances, Tom."
"I"ll not."
The adventurers were in the forward part of the ship, and Tom had taken his place at the wheels and levers in the pilot house. As he was about to start the motor he looked toward the road, and saw a horse and carriage. In the vehicle was a girlish figure, at the sight of which Tom blushed and smiled. He waved his hand.
"I came to wish you good luck!" cried Mary Nestor, for it was she in the carriage.
"Thanks!" cried Tom, leaning from the window of the pilot house. "It was good of you to get up so early."
"Oh. I"m always up early," she informed him.
"Look out that the motor doesn"t scare your horse," Tom warned her.
"Old Dobbin doesn"t mind anything," was her answer. "I"ll see that he doesn"t run away with me, as long as you"re not on earth to rescue me.
Good-by, Tom!"
"Good-by!" he called, and then he pulled the lever that set in motion the motor, and whirled the great propellers about. They whizzed around with a roar, and the Red Cloud, shivering and trembling with the vibration, rose in the air like some great bird.
"We"re off for the West and Phantom Mountain!" called Tom to his companions.
As the airship soared upward, Eradicate Sampson ran forward from where he had been standing near his mule Boomerang. He waved his hands, and shouted something.
"Bless my hatband! What does he want?" asked Mr. Damon, watching him curiously.
"It sounds as if he were calling to us to come back," spoke Mr. Parker.
"It"s too late now," decided Tom. "Maybe he forgot to tell us good-by,"
but, he felt a vague wonder at Eradicate"s odd motions; for the colored man was pointing toward the stern of the airship, as if there was something wrong there. But the Red Cloud soared on.
CHAPTER IX--A WARNING BY WIRELESS
Rapidly the airship ascended, and, when it was high over the town of Shopton, Tom headed the craft due west. Looking down he tried to descry Mary Nestor, in her carriage, but the trees were in the way, their interlocking branches hiding the girl. Tom did see crowds of other persons, though, thronging the streets of Shopton, for, though the young inventor had made many flights, there was always a novelty about them, that brought out the curious.
"A good start, Tom Swift," complimented Mr. Parker. "Is it always as easy as this?"
"Starting always is," was the answer, "though, as the Irishman said, coming down isn"t sometimes quite so comfortable."
"Bless my gizzard! That"s so," cried the eccentric Mr. Damon. "Can we vol-plane to earth in the Red Cloud, Tom?"
"Yes, but not as easily as in the b.u.t.terfly. However I hope we will not have to. Now, Mr. Damon, if you will just take charge of the steering apparatus for a minute, I want to go aft."
"What for?"
"I wish to see if everything is all right. I can"t imagine why Eradicate was making those queer motions."
Mr. Damon, who knew how to operate the Red Cloud, was soon guiding her on the course, while Tom made his way to the rear compartments, through the motor room, where the stores of supplies and food were kept. He made a careful examination, looking from an after window, and even going out on a small, open platform, but could discover nothing wrong.
"I guess Rad was just capering about without any special object," mused Tom, but it was not long after this that they learned to their dismay, that the colored man had had a method in his madness.
On his way back through the motor room Tom looked to the machinery, and adjusted some of the auxiliary oil feeders. The various pieces of apparatus were working well, though the engine had not yet been speeded up to its limit. Tom wanted it to "warm-up" first.
"Everything all right?" asked Mr. Damon, as Tom rejoined them in the pilot house, which was just forward of the living room in the main cabin.
"Yes, I can"t imagine what made Rad act that way. But I"ll set the automatic steering gear now, Mr. Damon, and then you will be relieved."
Mr. Jenks was gazing off toward the west--to where he hoped to discover the secret of Phantom Mountain.
"How do you like it?" asked Tom.
