When John heard what had happened, on his return to work, he was considerably disturbed, and suggested to his comrades the advisability of placing a night-guard on the premises for a while at least, since this unknown enemy might make an effort some night to burn or irreparably damage the Sky-Bird. The others sanctioned this precaution, and thereafter took turns in watching, although this vigilance was apparently all for naught, as no suspicious character appeared.

CHAPTER VIII

THE SKY-BIRD II

"Well, Mr. Giddings, what do you think of Sky-Bird II?" asked John
Ross, one memorable day.

There was a smile of deep satisfaction on John's own bronzed features as he put the question, a smile which was duplicated on the faces of his three co-workers—Paul, Bob, and Tom Meeks. It was the latter part of March, Easter vacation week for Paul and Bob, and the two chums had been working every one of the last three days helping John and Tom put the finishing touches on the big new airplane. And now this Friday morning it rested gracefully upon its own rubber-tired wheels, its great stretch of wings spread out as airily as those of a monster bird, its huge two-bladed propeller glistening like burnished silver, and its body running backward in a splendid symmetrical taper, to end at the well-proportioned tail. Sky-Bird II was done at last.

Mr. Giddings was so lost in admiration at the beautiful lines of the craft that he did not reply immediately to John's question. He had not seen it for almost two weeks, and in that time, under the onslaughts of the four boys, it had changed appearance in a striking way, numerous finished parts having been connected and paint and varnish having been applied.

"All I have to say, young men, is that if she performs anywhere near as well as she looks, I shall be thoroughly satisfied with the money I have invested thus far," declared the great newspaper man with an enthusiasm which he did not try to conceal. His eyes were shining, as he walked around the craft looking at it from all sides. He rubbed his fingers lingeringly over the smooth fuselage, and smiled quietly as he regarded the name "Sky-Bird II" lettered in large blue characters on her sides and underneath each long bird-like wing. Then he mounted a folding step and went through a neat door into the glass-surrounded cabin. This was deep enough to stand up in, and provided comfortable upholstered cane seats for the pilot and four passengers or assistants. All of these seats except the pilot's and observer's were convertible, forming supports for the swinging of as many hammocks, and in a small space at the rear was a neat little gasoline-burner, and over it a built-in cupboard containing some simple aluminum cooking ware.

"Well, I declare!" said Mr. Giddings in amazement at the convenience of things, "it looks as if you fellows hadn't left out a single item needed in a long and enjoyable cruise."

"There's nothing like being fixed up for all emergencies, sir," laughed John. "As you notice, we have everything for night-flying as well as day-flying. With such a machine as this there is no reason why a crew of four or five could not run nights as well as days, two operating while the others sleep in the hammocks. Cold foods can be cooked or warmed up on the gas-stove when needed, and the enclosed cabin protects all hands from the worst effects of bad storms."

"Wouldn't this glass break in a hailstorm?" asked Mr. Giddings. "It seems to be pretty thin."
