The Flying Machine Boys on Duty / The Clue Above the Clouds
CHAPTER I
An aviator, swinging northward in a June twilight, found himself constantly annoyed by the driver of a machine whose only motive in life seemed to be to get in the way. Turn as he might to right or left, sail high or low, the obstinate and impertinent pursuer was always at hand to threaten him.
To the west, lay Bedloe’s island, showing the Statue of Liberty, ruddy in the sunlight. To the east, Governor’s island presented the battlements of Fort Columbus and Castle William. To the north, or to the northeast, to be more exact, lay Battery park, a smear of green at the lower end of Manhattan island.
For a time people on ferryboats traversing New York bay looked upward in momentary expectation of a battle in the air. Then the two flying machines passed north along the line of Broadway, crossed over Bronx park, and came to the vicinity of Pelham bay, in Westchester county.
Here the aviator who had shown such pugnacity in his dashes and swirls at the other, and who had been repulsed only by the finest skill and tact, wheeled straight to the west and was soon lost to sight in the gathering darkness.
For a moment it seemed that the aviator who had thus far acted only on the defensive was about to become the aggressor and follow in the wake of his persecutor. In fact, he was about to swing away in pursuit when the ringing of a bell at a hangar below attracted his attention. Then, with a frown showing on a boyish face, he swung to the north a short distance and volplaned to a level space in front of the hangar.
Descending from his seat, the aviator was greeted, rather anxiously it seemed, by two boys not far from his own age. Very little was said until the flying machine had been run into the great shed, and then the three turned away to a rather elaborate office building which stood in a grove of trees at the entrance to the grounds.
A chill wind was blowing off Long Island sound, and the boys found a grate fire burning brightly in a private room at the rear of the structure. They seated themselves before the leaping flames and looked expectantly into each other’s faces for a moment before speaking.
Those who have read the opening volume of this series will need little introduction to James Stuart, Ben Whitcomb and Carl Nichols. Street boys of sixteen, they had, some months before, met Louis Havens, the famous millionaire aviator, and accompanied him on a trip to Mexico which had brought both fame and fortune to every member of the party.
On their return to New York from the “Burning Mountain” the boys had planned a course in college, but, at the request of Mr. Havens, they had promised to undertake a daring commission from the New York chief of police. A short time before their return to the city the night-watchman of the Buyers’ Bank had been murdered, the monster safe dynamited, and thousands of dollars in currency and securities taken.
It was believed by the chief of police that the burglars—two of the craftiest and most desperate criminals on the continent—were in hiding in the wild and mountainous region south of Monterey bay, on the Pacific coast.
On the theory that the Flying Machine Boys would be able to visit every nook and corner of the region where the criminals were supposed to be, with comparative ease, in their new and up-to-date machines, and, also, that the appearance of the lads in that section would not be apt to arouse the suspicions of the hunted men, the chief of police had proposed the journey to Havens, and he had induced the boys to accept the almost princely offer made by the official.
On account of the hazardous nature of the proposed trip, and because of the long distances to be traveled, special attention had been given to the Louise and the Bertha, the two aeroplanes ordered made by the boys immediately upon their arrival at New York. These machines had been completed the previous day, and the trip over New York bay made by Jimmie Stuart that afternoon had been the first tryout for the Louise, a very strong aeroplane, capable of carrying, when necessity required, two passengers and at least a hundred pounds of camp equipage and provisions.
“Who’s your friend?” asked Carl Nichols, short, fat, blue of eyes and pink of skin, as the three boys sat before the open grate fire in the private room in the office building at Havens’ hangar.
“He’s no friend of mine!” Jimmie Stuart, red-headed and freckled-faced, declared. “He picked me up down on the Jersey coast and did his best to get me into a mix-up. I dodged him all the way to Bronx park because, you see, I was not quite sure of my machine.”
“Did you get a good look at the fellow?” asked Ben Whitcomb, grave-faced, athletic, and inclined to worry over troubles which had not yet materialized. “It looked to me as if you might have slapped his face, he was so near to you when you passed over Battery park.”
“Oh, yes!” Jimmie answered. “I got a view of his face from almost every angle! He’s a low-browed brute, with ears like wings, and a hunch in his shoulders which makes you think of one of the muckers at Croton dam.”
“He certainly can run a machine, though!” Carl Nichols declared, “and he has an aeroplane that can go some, too!”
“But what’s the idea?” asked Ben. “Why should he be chasing you around in that impudent way?”
“I’ve got a notion,” Jimmie replied, “that he wanted to try out the Louise. He resorted to every trick known to airmen to induce me to make some kind of an error in handling the machine. He’s an expert himself, and he evidently wanted to know whether I am capable of operating a peach of a flying-machine like the Louise.”
“I don’t believe it was just idle curiosity that made the fellow stick to you in that way,” Carl interrupted. “I’ve been thinking that the purpose of our trip to the Pacific coast may have become known to friends of Phillips and Mendosa, the men who are believed to have dynamited the safe of the Buyers’ Bank and murdered the night-watchman. The crooks may have men on guard here!”
“That seems hardly probable,” Ben suggested. “The police have a pretty good case against Phillips and Mendosa, and, so far as my knowledge goes, a crook who stands in the shadow of the electric chair has few friends willing to interest themselves in his behalf.”
“Yes, but look here,” Jimmie argued, “Phillips and Mendosa lifted thousands of dollars in currency. So far as the officers know they still have the entire proceeds of the robbery in their possession. Even murderers with so many dollars in their possession are not likely to lack capable friends.”
“I guess that’s right,” Carl put in, “and the two murderers will of course scatter money like water in order to keep out of the clutches of the law!”
“Yes,” Ben suggested, “the clues point so directly to Phillips and Mendosa that they would naturally spend every dollar they stole in order to keep away from the New York officers.”
While the boys talked, the door to the private office opened softly. Mr. Havens stood for a moment on the threshold and then stepped up to the fire. The young man was tall, slender and supple, with a dusky complexion and black hair and eyes. He was twenty-four years of age, but looked much younger. The millions he possessed had been inherited from his father, and instead of spending them along the Great White Way, he was devoting his entire attention to aviation.
“What’s the argument, boys?” he asked, standing before the grate with a smile on his face. “Machines working all right?”
“Finely!” replied Jimmie. “I had a fine ride over the bay this afternoon. The Louise motor runs like a watch!”
“I saw you from Battery park,” Havens answered.
“Then
