With these jerky sentences, the occupant of the monoplane pulled a lever and turned a wheel on the side of the body of his machine. Instantly it rose, as gracefully as a butterfly, skimmed above the corn patch, circled around the boys’ astonished heads, and then dropped lightly in front of the shed which housed its ponderous rival of the skies.

As it came to a standstill the boys ran up to greet its operator, who, although he appeared rather fat and podgy, had already leaped nimbly to the ground.

“This is Mr. Pythias Peregrine?” inquired Jack politely.

“My name—glad to see you—dropped in, as it were—how do you do?—quite well?—glad to hear it.”

“Mah goodness,” exploded Jupe, leaning on his hoe and scratching his woolly head, “dat dar Jerry Green talks lak he had a package of firecrackers in him tummy.”

CHAPTER II—THE VANISHING GUN

Mr. Peregrine, having alighted from his Red Hawk, removed his helmet and goggles and mopped his forehead vigorously—for the day was warm, it being about the middle of August. The removal of his headpiece revealed him as a round-faced, good-natured looking man, with a rosy complexion and deep-set, twinkling blue eyes. Having taken off his goggles, he replaced them by a pair of big horn-rimmed spectacles, which, somehow, gave him an odd resemblance to an amiable bull-frog. Indeed, his explosive way of talking was very much at variance with his rotund figure and appearance of “easy-goingness.”

“Naturally want to know what I came to see you about? Of course. Father at home?—No. Recollect you said in your telegram he was in Washington. Very warm, isn’t it?—It is.”

“I got on the long-distance telephone as soon as I received your message,” rejoined Jack, finding it rather hard to keep a straight face as Mr. Peregrine rapidly “popped” out the above sentences. “He said he recalled you very well as an old scientific friend, and that anything that we could do to aid you we were to do. Both my Cousin Tom and myself will be very glad to help in any way you may require. By the way,” as Mr. Jesson came up, “this is my uncle, and Tom’s father, Mr. Jasper Jesson.”

“Jasper Jesson, eh? Noted explorer?—Yes. Lost in Yucatan?—You were. Did I read about it in the papers?—I did. Columns of it. Was it interesting?—Very. Glad to meet you, sir. Glad to meet you.”
