On a Torn-Away World Part 2

The sensation of being so high above the earth, and in imminent danger of being dashed headlong to it, gripped Mark Sampson like a giant hand. He felt difficulty in breathing, although it was not the height that gave him that choking sensation. There was a mist before his eyes, still the sun was shining brightly. The startling gyrations of the flying machine for some time shook the lad to the core.

But Jack's cheerful cry of "Hang on!" spurred Mark to a new activity--an activity of hand as well as brain. He knew that something had fouled and that this accident was the cause of the machine making such sickening bounds in the air. She was overbalanced in some way.

With Jack's encouraging shout ringing in his ears, Mark came to himself.

He _would_ hang on! His friends depended upon him to control the machine and to save them from destruction, and he would not be found wanting.

One lever after another he gripped and tried. It was one controlling the rising power that was fouled. He learned this in a moment. He sought to move it to and fro in its socket and could not do so. He had overlooked this lever before.

Again the _s...o...b..rd_ dashed herself from a height of five hundred feet toward the earth.

They still flew over the forest. The tops of the trees intervened, and Mark managed to counteract the plunge before the prow of the machine burst through the treetops. She rose again, and using both hands, Mark jerked the wheel stick into place.

At once the flying machine responded to the change. She rode straight on, slightly rising as he had pointed her, and Mark dared touch the motor switch again. Instantly the machine speeded ahead.

"Hurrah for Mark!" shrieked Jack. "He's pulled us through."

"He has indeed," agreed the professor, and they settled into their seats and gave attention to the working of the apparatus. Mark now had the _s...o...b..rd_ well under control.

Jack changed places with his chum and managed the _s...o...b..rd_ equally well. At his touch she darted upward at a long slant until the altimeter registered two thousand feet above the sea. And the sea was actually below them, for Jack had guided the flying machine away out from the land.

"Boys," said Professor Henderson, quietly, "you have done well--remarkably well. I am certainly proud of you. Some day the people of the United States will be proud of you. I am sure that the inventor's instinct and the scientist's indefatigable energy are characteristics you both possess."

"That's praise indeed!" exclaimed Jack, smiling at his chum. "When the professor says we've won out, I don't care what anybody else says."

"Do you think the _s...o...b..rd_ is fit for long-distance travel?" asked Mark of Professor Henderson, now displaying more eagerness than before.

"I do indeed. I think you have a most excellent flying machine. I would not hesitate to start for San Francisco in her."

"Or farther?" asked Jack.

"Certainly."

"Across the ocean?" queried Mark, quickly.

"I do not see why any one could not take a trip to the other side of the Atlantic in your 'plane," replied the professor. "With proper precautions, of course."

They reached the land and came safely to rest before the hangar without further accident. The professor was delighted with the working of his catapult and at once made ready to call the attention of the Navy Department to his improvement in the means of launching an airship from the deck of a vessel. Ere he had written to the Department, however, he and his young friends were suddenly made interested in a scheme that was broached by letter to Professor Henderson from a fellow-savant, Dr. Artemus Todd, of the West Baden University.

Professor Henderson and Dr. Todd had often exchanged courtesies; but the university doctor was mainly interested in medical subjects, while Mr. Henderson delved more in the mysteries of astronomy and practical mechanics.

The doctor's letter to Professor Henderson read as follows:

"Dear Professor:

"I am urged to write to you again because of something that has recently come to my knowledge regarding a subject we once discussed. As you know, for some years past I have been investigating not the _cause_ of aphasia and kindred mental troubles (for we know the condition is brought about by a clot of blood upon the brain), but the means of quickly and surely overcoming the condition and bringing the unfortunate victim of this disorder back to his normal state. In our age, when mental and nervous diseases are so rapidly increasing, aphasia victims are becoming more common. Scarcely a hospital in the land that does not have its quota of such patients under treatment--patients who, in many cases, have completely forgotten who and what they are and have a.s.sumed a totally different ident.i.ty from that they began life with."

"We know that, in some cases, hypnotism has benefited the aphasia and amnesia victim. His condition is not like that of the mentally feeble; he has merely lost his memory of what and who he previously was.

Believing that all disease, of whatsoever nature, can be safely treated only through the blood, _this_ ill to which human flesh is heir particularly must be treated in that way, for we know that a stagnant state of the blood in one spot, at least, is the cause of the patient's malady. Therefore I have been experimenting botanically to discover a remedium for the state in question--something that will act swiftly upon the blood, and directly dissipate such a clot as is spoken of above."

"My dear Professor! I can announce with joy that this remedium is discovered. I obtained a specimen of a very rare plant brought back from Alaska by a miner who wandered into the fastnesses of the Endicott Range, far beyond the usual route of gold miners and in a district which, I understand, is scarcely ever crossed by whites and which is, indeed, almost impa.s.sable, even in the summer months. With the aid of this herb--_Chrysothele-Byzantium_ (it was known to the ancients, but very rare)--I have brewed a remedium which, in one case at lest, instantly cleared the blood vessels of the patient and brought him back to a knowledge of his real self."

"But my supply of the herb is gone. It reached me in its dry state, or I should have first tried to propagate it. It seeds but once in seven years and therefore is rare and hard to grow. But I must have a supply of the _Chrysothele-Byzantium_ seeds, plants, and all.

I look to you, my dear Professor Henderson, for help. To you s.p.a.ce and the flight of time are merely words. You can overcome both if you try.

I need somebody to go to the northern part of Alaska--that is, beyond the Endicott Range--to obtain this rare plant for me. You have already flown over the North Pole and a trip which carries one only three or four degrees beyond the Arctic Circle is a mere bagatelle to you."

"Yes! it is in you I place my hope, Professor. The hopes of many, many afflicted people may be placed in you, too. I ask you to fly to this distant place and obtain for me the herb that will do humanity such great good. Under another enclosure I send you drawings of the plant in its several states and a full and complete description of how it was found. You can make no mistake in the _Chrysothele-Byzantium_.

You know that I am a cripple, or I would offer to join with you in this search. But at least I am prepared to pay for any expense you may be under. Draw upon me for ten thousand dollars to-morrow if you so desire, and more if you need before the start. The Ma.s.sachusetts Bay Trust Company, of Boston, will honor the draft. Make up the expedition as you see fit. Take as many men with you as you think necessary. Make all preparations which seem to you fit and needful. I limit you in nothing--only bring back the herb."

"Remember I shall impatiently await your return and look for your success--I expect nothing but unqualified success from your attempt.

You who have achieved so much in the past surely cannot fail me in this event. I await your agreement to attempt this voyage with confidence. I must have the herb and you are the only person who can obtain it for me."

"Your friend and co-worker for the betterment of humanity, ARTEMUS TODD, M.D., Ph.D."

Professor Henderson read this strange letter aloud in the evening as he and his friends were sitting before the small, clear fire of hickory logs in the big living room of the bungalow in the woods, built beside the great workshops and laboratory. With the scientist and the two boys was Andy Sudds, the old hunter, who sat cleaning his rifle, and Washington White was busy in and out of the room as he cleared away the supper and set the place in order.

"Well! what do you know about that!" exclaimed Jack Darrow, always ready with a comment upon any subject. "Dr. Todd is certainly some in earnest; isn't he?" "But what a cheek he has to ask you to go on such a journey!" cried Mark. "He talks as though he expected you to start immediately for the Arctic Circle."

"There would be good hunting up there in the mountains," said Andy Sudds, succinctly. "I wouldn't mind that."

"An'disher chrysomela-bypunktater plant he wants," grunted Washington.

"Hi, yi! ain't dat de beatenest thing? Who ebber heard of sech a plant befo'?"

"n.o.body but you, I guess, Washington," said the professor, quietly.

"_That_ seems to be a plant of your own invention."

"But, sir!" cried Mark, "you have no idea of taking this trip he suggests; have you?"

"Dr. Todd has done me many a favor in the past," said Professor Henderson, thoughtfully.

"Well, if you're going, count me in," said Jack, quickly. "I don't mind a summer trip to the Arctic. Say! it can't be much cooler up there than it is here right now. This fire doesn't feel bad at all."

"Humph!" muttered Mark, who never was as sanguine as his chum. "This cool spell will only last a day or two here; but I understand the tops of the Endicott Range are always white."

"B-r-r!" shivered Washington, at this statement. "Dis chile don't t'ink much ob such a surrept.i.tious pedestrianation as dat, den. Don't like no cold wedder, nohow! And b.u.t.tsy don' like it, needer."

"Who's b.u.t.tsy?" demanded Jack, grinning.

"Why, fo' suah," said the darkey, gravely, "you knows Christopher Columbus Amerigo Vespucci George Washington Abraham Lin----"

"But you wouldn't expect to take Christopher Columbus And-so-forth to Alaska with us; would you?" asked Andy Suggs.

"Why not?" demanded the darkey. "He flowed to de moon in de perjectilator; didn't he? Huh! In co'se if de perfessor goes after disher chrysomela-bypunktater, I gotter go, too; and in co'se if I go, b.u.t.tsy done gotter go. Dat's as plain as de nose on yo' face, Andy."

The hunter rubbed his rather prominent nasal organ and was silenced.

Jack and Mark had turned more eagerly to the professor as the latter began to speak:

"Yes, Dr. Todd is my good friend. He turns to me for help quite properly; who else should he turn to?"
