“That is not nearly all that these gallant boys have done,” declared the narrator, after a time. “I could sit here for an hour and tell you innumerable instances where Rob, and some of his chums into the bargain, did things that would be counted big under ordinary conditions. Why, it has come to that pass in Hampton nowadays that when anything beyond the ordinary is attempted they have to get the scouts interested in it first, and then people begin to believe it must have some merit.”

“What you tell me is indeed wonderful,” declared the professor. “After that recommendation I am strongly disposed to offer them the carrying out of my mission if they could see their way clear to accept the task.”

“It would give them a chance to spend some weeks at the Exposition without incurring any expense, is that the idea, Professor McEwen?” asked the judge, who looked as happy as though he had discovered some wonderful bug which had been eagerly sought after for years and years by all scientists and collectors.

“Yes, a month, if they cared to stay that long,” replied the other, who seemed to have been fully convinced, and ready to throw the load of responsibility from his own shoulders to those of Rob and his chum. “The particulars can be gone over a little later, either to-night, if they care to see me again, or to-morrow. There is no great need o’ haste, though what I am carrying out to California is being eagerly expected by my colleagues there.”

“Let me congratulate you, boys, on your good fortune,” said the kindly judge, as though he wished to settle the matter in such a fashion that there could be no drawing back on the part of the gentleman. He then shook hands first with Rob and then with Andy Bowles.

Rob was looking a little pale from excitement, but there was also a happy glow in his eyes. As for Andy, he could not prevent a wide grin from spreading over his features. His father owned a livery stable in Hampton, but was not considered at all well-to-do, so that the boy had never been able to do more than dream of taking expensive trips. That one down into Mexico had come like a gleam of golden sunshine, for Tubby Hopkins’ old uncle had footed all the bills.

“Do I understand you to make this proposition to us, Professor McEwen?” Rob asked bluntly, not wishing to be laboring under any delusion.

“Aweel, aweel, I dinna ken how I could do better; and I feel that I am indebted to ye baith for my life. After hearing what bonny lads ye are, from my friend Judge Collins here, whose opinion carries great weight wi’ me, I am mair than pleased to offer to stand all the cost of a trip to California and back; as well as the expense which you will necessarily be under while seeing the great Exposition in San Francisco. Do ye think ye can ha’e the permission of the auld folks to take so lang a journey?”

“There will be no trouble on that score, Professor,” urged the judge. “These lads have so amply demonstrated their sterling ability to look out for themselves that I really believe Rob’s parents would not object if he wanted to go to hunt for the South Pole, or explore the unknown regions of tropical Brazil. And so we shall call it settled, I presume, Professor?”

“I ha’e made the offer, and shall tak’ it hard if they turn it down,” said the peculiar little man of science, whose name, Rob afterward learned, was known throughout the whole length and breadth of the world wherever men of intellect gathered to discuss their theories and discoveries.
