CHAPTER VI.

“WHAT WOULD YOU SAY TO A VOYAGE IN THE AIR?”

After breakfast the next morning, the professor appeared on the bridge

with Nat when the latter took his daily observation, a practice which

was, of course, in addition to the regular “shooting the sun,” which

took place at noon. The man of science had already made a deep

impression on the lad. He was eccentric to a degree; but in common with

many men of ability, this was a characteristic that in no way appeared

to affect his scientific ability. The evening before he had entertained

all hands with fascinating tales of his experiences in various parts of

the world. Already everybody felt the same respect for Professor Grigg

as was manifest in the manner of the irrepressible Tubbs.

Nat operated his instruments and then noted the result on a pad, to be

entered later in the log book. The professor peered over his shoulder

as he jotted down his figures.

“Pardon me,” he observed, “but you are a hundredth part of a degree out

of the way on that last observation.”

For an instant Nat felt nettled. He colored up and faced round on the

scientist. But Professor Grigg’s bland look disarmed him.

“Is that so, professor?” he asked. “How is that?”

“Let me test your instruments,” was the reply. “It is impossible to

tell without that.”

Nat handed the various instruments over to his learned companion. The

professor scrutinized them narrowly.

“I think,” he said finally, “that the magnetic influences of

yesterday’s storm have deflected all of them.”

“Of course,” agreed Nat. “How stupid of me not to have thought of that!

Is it possible to adjust them?”

“I will try to do so,” said Professor Grigg, and, placing a sextant to

his eye, he began twisting and adjusting a small set screw.

Several times he lowered the instrument, and, taking out a fountain pen

and a loose-leaf notebook, wrote down his readings. Nat watched him

with some fascination. There is always a pleasure to a clever lad in

watching a man doing something which he is perfectly competent to do.

The professor, the instant he laid his hands on the instruments,

impressed Nat as possessing the latter quality to a degree.

“Just as I thought,” said the professor finally, “your instruments have

been deflected. But we will set them right at noon. A few simple

adjustments, that is all. But I find that you have kept them in

wonderful shape, considering your rough and trying experiences.”

“We have always tried to,” said Nat. “We knew how much depended on

them.”

“And yet,” mused the professor, with his eyes fixed intently on Nat, as

the lad stood at the wheel, “without the ability to understand them,

those instruments would be worthless. Conradini, the Italian explorer,

learned that.”

“At the expense of his life,” put in Nat. “The lesson was lost.”

“Ah, you have heard of Conradini?” asked the professor, in seeming

surprise.

“I have read of him in that pamphlet on aerial exploration issued by

the Italian Royal Society,” was the reply.

The professor readjusted his glasses. In his astonishment, he almost

lost his latest piece of headgear—loaned him by Ding-dong. It was a not

too reputable-looking Scotch tam o’shanter.

“You have a knowledge that surprises me in one so young,” he declared

at last. “You take an interest in exploration, then?”

“That was the object of the Motor Rangers, when first we founded them,”

declared Nat. “I think,” he added, with a twinkle in his eye, “that

we’ve had our fair share of adventure.”

“From what you have told me of your enterprises, I agree with you,”

assented the professor warmly. “But you have not told me yet of the

future.”

“How do you mean?” asked Nat.

“I mean, what plans have you ahead of you? What do you intend to do

next?”

The question came bluntly. Nat answered it with equal frankness.

“I really don’t know,” he said. “As you are aware, though, our course

is now laid for Santa Barbara.”

“So you said last night, when you kindly offered us a passage home,”

said the professor.

He paused for an instant, and Nat swung the _Nomad’s_ bow around a

trifle more to the south.

“Have you no plans for further adventurous cruises or auto trips?”

pursued the man of science.

Nat laughed.

“I guess we’ve had our fill of adventure for a time,” he said; “that

cleft between the volcanic islands nearly proved our Waterloo.”

“Nonsense; such lads as you could not live without adventure,”

admonished the professor, making a frantic grab at his hat, as a

vagrant wind gave it a puff that set it rakishly sidewise above one

ear. “Do you mean to say that you feel like settling down to humdrum

life now, after all you have seen and endured?”

“I guess we all feel like taking a rest,” said Nat. “We have had a

fairly strenuous time of it lately.”

“Granted. But it has put you into condition to weather further times of

stress and trial. Ever since we had that talk last night about the

Motor Rangers, and what they have accomplished, it has been in my mind

to broach a proposition to you.”

“To us?” temporized Nat. “I don’t see where we could be of any use to

Professor Thaddeus Grigg, the most noted scientist of investigation of

this age.”

The professor raised a deprecatory hand.

“As if you had not been of the highest service to me and to my

companion already,” he exclaimed. “Had it not been for you, we might

have—oh, well, let us not talk about it. That coward of a captain——”

He broke off abruptly. Nat waited for him to resume speaking.

“What I wanted to approach you about was this,” resumed the professor,

after a minute. “From the moment I met you, you appeared to me to be

self-reliant, enterprising boys, who mixed coolness and common sense

with courage. Such being the case, you are just the combination I have

been seeking for, to carry out a project which awaits me on my return

to America. It is a scheme involving danger, excitement and rich

rewards.”

He paused impressively. In spite of himself, Nat’s eyes began to dance,

his pulse to beat a bit faster. Adventure was as the breath of life to

the young leader of the Motor Rangers, and, to tell the truth, he had

faced the prospect of a life of inactivity with mixed feelings.

“Well, sir?” was all he said, however.

The scientist continued, with apparent irrelevance.

“You three lads, from what you have told me, have operated motor cars,

motor boats, and endured much in both forms of transportation?” he

asked.

Nat nodded.

“I guess we’ve had our share of the rough along with the smooth,” he

said briefly, but he was listening closely.

“What would you say to trying a voyage in the air?” was the question

that the man of science suddenly launched at him without the slightest

warning.

Nat glanced up from his steering amazed. The scientist met the lad’s

gaze firmly.

“Well?” he demanded.

“I—I—upon my word, I don’t know,” stammered Nat.

For once in his life, the young leader of the Motor Rangers was fairly

taken aback.
