During the two weeks which followed, the elder Austins, under the able tutelage of Mr. Kramer, and the additional assistance of their sons, became remarkably proficient in flying the ranch plane, also, the Sky Buddies became thoroughly acquainted with the “Lark,” which was the name of their own super-machine. Then the salesman removed himself to Crofton, where his firm had a new plane waiting for him and he expected to demonstrate it for prospective purchasers. Already the sheriff was watching its performance with keen interest and it looked as if that worthy might become the possessor of one of the birds. Although the boys spent a good deal of time in the air, neither of them neglected his studies with Don Haurea, and Caldwell could hardly wait until spring came in order to put some of his information into practice. One afternoon, Mr. Austin came out of his office with a letter which had come in the morning’s mail.
“Oh, Jim.”
“Yes, sir.” The boy hurried to learn what was wanted, and presently they were seated at the big desk.
“I may go to South America,” the man announced thoughtfully.
“Golly, what a trip that will be, Dad,” the boy exclaimed. “Be gone long, sir?”
“I do not know. It’s a matter of business and I was rather hoping that my part of it could be transacted from here, but I have received a confidential letter in which one of my associates urges me to come personally and look after my interests,” he answered thoughtfully.
