THE MYSTERIOUS STEAMER

In the wake of an easterly squall the sloop Arrow, Lemuel Vinton master and owner, was making her way along the low coast, southward, from Snipe Point, one of the islands in Florida Bay about twelve miles northeast of Key We st.

With every sail closehauled and drawing until the bolt ropes creaked under the strain, the Arrow laid a fairly straight course toward Key We st. She bore a startling message, the nature of which her captain had considered of sufficient importance for him to prolong a cruise he had undertaken and to hasten back to the port whence he had sailed, twenty-four hours previously, to inform the authorities.

The sloop had not sped far from the Point, and the receding shore line had scarcely grown dimly blue on the horizon under a peculiar yellow-gray sunrise, when Captain Vinton's crew began to make their appearance on deck. The crew consisted of five Boy Scouts, an older companion who was in charge of them, and a Seminole Indian guide, called Dave, who had been hired to conduct the boys on a brief exploration of the Everglades. Four of the boys belonged to a troop of scouts who had their summer headquarters at Pioneer Camp, far away among the New England hills. They had, however, formed a resolution to spend the present summer not at Pioneer Camp, where most of their younger comrades would be, but in seeing some new sections of their native land. To this end, three of them—-Hugh Hardin, his chum Billy Worth, and Chester Brownell—-had gladly accepted an invitation from the fourth, Alec Sands, to spend a month at Palmdune, the Florida residence of Alec's father, who had sent them on this cruise. With them Mr. Sands had sent his secretary, a young man named Roy Norton, who had left them temporarily at Key We st while he attended to business in Havana. When he had returned from Havana, he had found a new member of the party—-Mark Anderson, the son of the captain of Red Key Life-Saving Station.

The Arrow had been anchored off Snipe Point during the previous night, where Captain Vinton had gained the information which made him decide to return to Key We st. This knowledge, which he had already imparted to the boys, was to the effect that throughout the night before, while he and Dave alternately watched, he had seen a gray steamer or perhaps a gunboat cruising among the islands off the Point, occasionally coming close enough to the beach to be made out distinctly, but showing no lights and making no signals.

Immediately his suspicions had been aroused by this mysterious action. His impression was that the vessel belonged to a country which was then hostile to the United States. In that case she was either grappling for the cable between Key We st and the mainland terminus at Punta Rossa, which lay close inshore at Snipe Point, or was trying to make connection with some other vessel carrying supplies or ammunition from some We st Indian port, perhaps intending to run the blockade.

Why she should attempt to tamper with the cable, he could not understand, knowing the superior efficiency of the wireless system; but he thought she might be one of the elusive filibustering vessels reported to have been seen in the Gulf of Mexico several days before this.

Stories about these mysterious vessels had caused official orders to be sent to Tampa and to Galveston, Texas, concerning the departure of several transports with American troops. And Captain Vinton himself had almost encountered a notorious filibuster named Juan Bego, one night during the earlier part of this pleasure cruise; that is, he had sighted a vessel which he felt sure was the Esperanza

of Captain Bego, in waters which were supposed to be debarred to the enemy. All this had tended to make him more alert and wary than ever, even suspicious; and he had resolved to lose no time in reporting his most recent discovery.

"You boys might as well heave them old tarpon poles overboard now,"he said seriously, as he shifted the helm."That there craft I seen las'night ain't Yankee built, I'll swear; and if she should take a notion to foller us, we want to be light and shipshape, without no signs o'lubberliness that the squall may have brought to the surface. How's everything in the cabin, Dave? Tight and neat?"

The Seminole grunted, nodding his head in affirmation. Apparently he was too disturbed in mind to reply verbally; besides, like most of his kind, he was a poor sailor, and he did not enjoy the speed at which the Arrow was now sailing. It upset his mental balance as well as his bodily equilibrium.

Obeying the captain's instructions, the boys tossed overboard their heavy poles, saving only the lines and reels.

"When we get back to Key We st, what's the first thing to do, Captain?"inquired Alec.

"Report seeing that steamer to the naval authorities,"was Vinton's prompt answer.

"I didn't know there were any——-"

"The re's likely to be some there now, waiting for orders."

"And will they search for the strange vessel?"

"You bet they will! We ain't goin'to let no sneakin'furrin tub show us her heels,—-are we, lads?"

"Not if we can help it!"exclaimed Hugh."I guess one of Uncle Sam's revenue cutters will give chase to that steamer, or gunboat, or whatever she may be."

"Not if she's a gunboat, I reckon!"quoth Vinton with a chuckle."Cripes! that vessel was certainly a clipper for goin'! Her cap'n was wise enough to keep to wind'ard, for he seemed to know where the rough water begins to rise and how to make the most o'them keys. Never mind; off Nor'west Cape he'll have to come out like a seaman and take his duckin'! H'ist that there jib, Billy, and make Dave move his carcass where it'll do some good."

But Dave did not want to bestir himself from his position on the weather gunwale, where he crouched dejectedly, letting the stiff breeze dry his spray-soaked garments. He groaned, protested, grunted, and finally swore volubly as Alec prodded him, while Billy hoisted the flying jib.

"What for so much hurry?"he grumbled."Get to Key We st by afternoon, anyhow. Dave want plenty sleep."

"You slept like a top for six hours last night!"declared Alec.

"No-o; Dave watch, saw steamer,—-no more sleep, no forty winks."

"Oh, come!"laughed Billy."I heard you snoring, Dave; you woke me up! I thought it was thunder!"

"Nothing less than thunder or a cannon firecracker would wake you up, Billy,—-as a general rule,"said Hugh, flinging one arm over his chum's shoulders and giving him a vigorous hug.

"Look yonder, boys!"shouted Captain Vinton at the helm. He pointed aft, and the four lads sprang to their feet and hurried toward him, alert and eager for a new surprise.

Some distance behind them, toward the mainland, a thin trail of smoke which had not been seen for two or three hours was now visible inside the keys. Could there be any reason for the reappearance of that smoky blur against the sky? Was it made by the mysterious steamer? If so, was she following the Arrow?

"By the shades o'shad, I orter know that boat!"exclaimed Vinton in puzzled chagrin."See? She's coaled up, goin'for all she's worth. Alec, git out my glass from the cabin, take a look, and see if there's many men aboard."

Alec ran to do the captain's bidding. Descending into the cabin, he took from a locker an old-style marine telescope with which he hurriedly returned to the deck. After some focusing he managed to catch a glimpse of the steamcraft, just before she partially disappeared from sight behind one of the sandy reefs that fence off the sound.

"The crew of the steamer seem to be quite excited,"Alec said, as he trained the telescope upon them."I can see sailors running across her deck, and two of them have just hoisted an American flag. Some others are waving signals and—-"

"What?"shouted the captain."American flag, did you say?"

"Yes. What do you think of that?"

"Reckon she wants to speak us."

"Why?"asked Chester.

"Looks like this is the first time she's seen us,"said Vinton, taking the marine glass from Alec."But it can't be the same craft we sighted back yonder, last night. Anyhow, if they're wavin'signal flags,—-and they are, sure enough!—-they must want to speak the

Arrow. That's plain. I'm goin'to ease in more and see who's aboard. Look! the dinged old boat is comin'out from behind the bar now."

Pondering some contingency which he did not explain to the boys, Vinton shifted the helm; and his sloop, hitherto heading in a southwesterly direction, now began to edge closer to the line of keys. Had Vinton not known his course so thoroughly from long experience in sailing these channels, inlets, and lagoons, it would have been dangerous; but he dexterously eluded the various reefs and oyster bars and brought the Arrow safely into smoother water. Meanwhile, the boys noticed that the wind, which had blown so strongly, was beginning to slacken, thus allowing the steamer to gain on the Arrow quite perceptibly. They saw then that she was a small steamer, like a steam yacht, and light gray in color,—-perhaps one of the United States revenue cutters.

Captain Vinton was astonished. He had already begun to have serious doubts that this could be the same mysterious vessel he had seen cruising about the islands the night before. All at once, unexpectedly, his doubts were resolved into a certainty that it was not the same, for even while he was wondering, a strange thing happened:

A long, low, gray shape, something like a built-for-speed tug-boat with a short funnel, darted into view from between two keys, and, crossing the wake of the revenue cutter, glided swiftly along the very course the Arrow had taken, heading back toward Snipe Point. Before the sloop and the steamer had come within hailing distance of each other, the strange craft, not depending on the dying easterly wind, was well along the course, sending back—-toward a trail of darker smoke.
