CHAPTER XI.

LOST IN THE FOG.

It is a week after the race and the Hempstead Plains cup proudly reposes in a place of state in the Chester boys' home. On the morning in question the boys and their chums are getting ready for a test of Frank's pontoons, which, as our readers know, he had already begun to figure on as soon as Bluewater Bill had unfolded his strange tale of the Golden Galleon of the Sargasso.

In a quiet bay on the north shore of Long Island the tests were to be made, and a launch had been engaged for the occasion. At the commencement of this chapter our readers are to imagine the boys on a train speeding toward Lone Cove, where they plan to embark. In the baggage car are the "pontoons," which in reality are two cylinders of aluminum, about twenty feet in length by three in diameter and capable of sustaining a weight of almost a ton. To the bottom of each, Frank had riveted a thin "keel" of manganese bronze with a heavy fin of lead affixed to it. This was to give stability in the rough waters they ran a chance of encountering on the outskirts of the Sargasso.

A space of about two feet at each end of the pontoons had been partitioned off, so as to form four tanks in which water and gasolene could be stored. Caps screwed over vent-holes provided opportunity to insert a small pump when it was necessary to draw on the emergency supplies or water ballast thus carried.

Lone Cove, a small sand-bordered inlet off the Sound, was reached after a run of about two hours and the tanks—boxed in long wooden cases so as to avoid the scrutiny of any villagers who might prove too curious—were transferred to a wagon and carried to the small wharf where the Ocean Spray, the launch the boys had chartered for their experiments, lay at anchor.

Her owner, an old beachman, at once turned the craft over to the party and expressed a lot of curiosity, which was not gratified, as the boys knocked the cases off the "pontoons" and then floated them. With the boards from the cases, a sort of platform was then constructed between the floating tanks and lashed to them with stout wire. The wonderment of the old waterman was in no wise decreased when he saw the boys then fall feverishly to work and load the dinghy, attached to the launch, with large stones. When they had her piled to the water line, they pulled out to where they had anchored the tanks with their bridge-like platform, and commenced to place the rocks on board till Frank estimated that there was as much weight reposing on the pontoons as they would be called upon to bear when the Golden Eagle was super-imposed on them.

As Frank had figured, the tanks were immersed for about a third of their depth under the weight, and when the burden of the boys and Bluewater Bill was added, they sank till about half their circumference was above and half below the water. The whole contrivance was then taken in tow of the Ocean Spray, in order to ascertain just how she would behave under the speed at which it was hoped the propellers of the Golden Eagle would drive her when the contrivance was affixed to her bed plates.

It was a perfect day, and as the boys emerged from the mouth of the inlet and the blue expanse of the Sound spread before them, they fairly shouted with delight at the sparkling water and invigorating air.

"How long are you going to stay out?" asked Bluewater Bill, as the Ocean Spray plunged bravely forward and the sharp-nosed pontoons, to the boys' delight, clove the water behind without making any noticeable resistance.

"The Golden Eagle will drive over any seaweed that ever floated on these," shouted Billy excitedly as he gazed back.

"How long are we going to stay out?" repeated Frank, in reply to Bluewater Bill's question. "Oh, not more than an hour or so, but it's such a glorious day I'd like to keep on going for a while."

"So would we," chorused the others.

"Wall," was the old-sailor's rejoinder, "I don't want to be a spoil-sport, boys, but do you see that haze yonder?"

Frank nodded.

Over on the Connecticut shore, which lay a low, blue line on the opposite horizon, a sort of haze, floating like a silken scarf, was indeed quite observable when attention was called to it.

"What is it?" asked Frank.

"It looks to me like fog," said Bluewater Bill, slowly, "but it may be nothing. Anyhow we've got time for a cruise afore it comes up, I reckon."

"Oh, lots of time," rejoined Frank confidently, as he gave the wheel a twist and sent the little Ocean Spray, a twenty-five foot craft, dancing clear into the sparkling seas that came tumbling along. As her sharp bow encountered them, the speedy little craft tossed the water in glittering cascades back over her foredeck. The pleasantly stinging spray blew in a moist cloud back in the young voyagers' faces.

"Say, Frank," exclaimed Billy, suddenly, "let me take a cruise on those pontoons, will you? I've read about rafts ever since I was knee-high to a bicycle pump, but I never rode on one."

"All right, Billy," laughed Frank, and after the queer craft astern had been drawn up by the tow-line the young reporter jumped aboard.

"Let out lots of rope," he cried, as the stone-laden contrivance bobbed about on the waves, "this is bully. A regular private yacht.

"Oh, a sailor's life is the life for me,
Out on the ocean, out on the sea;
Out with the whales, out with the shark,
If a cat-fish mews does a dog-fish bark?"

The Ocean Spray once more forged ahead, and so absorbed were the boys in putting the little ship through her paces that not one of them noticed a curious change that was gradually taking place in the weather. The air had grown more chilly and an almost imperceptible film of mist was creeping over the sun-warmed waters. If Bluewater Bill had not dropped into the little cabin for a snooze he would have warned the boys of their peril, but, as it was, their first realization of the fact that the fog was upon them was their complete envelopment in a dense blanket of dripping mist.

If a curtain had rolled down all about them they could not have been more completely blotted out from their surroundings.

Everywhere the soft white mist baffled sight. From the stern of the
Ocean Spray it was impossible to make out the tiny vessel's bow.

The smothering blanket of pearly-gray vapor had enwrapped them so completely that in their first excitement they lost all sense of their bearings, and as they had no compass they were in a bad fix indeed.

Hastily Frank awoke Bluewater Bill.

The old sailor uttered a sharp exclamation as he emerged from the cubby hole in which he had been sleeping and gazed about him. The fog settled in glittering masses on his bushy eyebrows and whiskers, as he scanned the impenetrable mist in every direction.

"Whereabouts was you when the fog came up?" he asked suddenly.

"About in the middle of the Sound," announced Frank.

"Couldn't be in a worse place," commented Bill, "right in the track of the Fall River steamers and any other craft that happens to come up or down the Sound."

Even as he spoke there came the long melancholy boom of a steamer's whistle from somewhere in the obscurity.

Bill hastily searched the Ocean Spray's cabin.

"Well, we are in a fix, boys," was his comment as he concluded his examination of the lockers and cupboards.

The boys looked their questions.

"Ain't a fog-horn nor a bell aboard this craft," was Bill's alarming intelligence, "we may get run down any minute."

Again through the fog came the roar of the approaching steamer's whistle.

Ominous, full of sinister possibilities, the voice of the nearing peril roared through the fog.

Suddenly there was a shout from astern.

"Hey there, I don't want to squeal, but I'm getting nervous. Have you forgotten me or am I adrift?"

"Billy Barnes!" cried Frank, "I had clean forgotten about him. Come on, boys, lay a hand on the tow-rope and we'll get him aboard."

The engine of the Ocean Spray had been cut off by Bill, when he first discovered that the little craft was as helpless to aid herself as a drifting log in the dense smother. She now rode the swells silently and powerless.

In response to Billy's hail, the boys shouted back:

"All right, Billy, we'll have you aboard in a minute."

"Hurry up, it's awful lonesome out here," came back Billy's cheerful hail through the fog.

Frank and Harry laid on to the rope and started to haul the pontoons and their freight inboard, but even as their hands closed on the rope the booming roar of the menacing steamer's whistle permeated the fog once more.

It seemed as if this time it was directly over them.

"Start the engine," cried Harry, as the full sense of their peril was borne in on him.

The shriek of the large vessel's whistle was now sounding almost in their ear-drums. Frank expected every minute to see the obscurity pierced by a huge black prow.

But as this thought flashed across him there came a sudden diversion. The tow-rope they were hauling on suddenly was torn from their hands, almost dragging them overboard, and though they could hardly see it they could "feel" the presence of a huge vessel going past not twenty feet astern.

"Billy!" shouted Frank as the tow-rope was jerked from his grasp.

The only reply was a grinding, rasping crash as if some great object were brushing resistlessly past a smaller one, and then the whistle boomed out again.

This time, however, its sound came in diminishing form and as the Ocean Spray cruised round blindly in the fog, searching in vain for any trace of the raft, it grew fainter and fainter and finally died away into the distance.

Half an hour later a breeze sprang up, the fog lifted almost as suddenly as it had closed in and the Sound once more shone in the sparkling rays of the afternoon sun.

The boys uttered a shout as they perceived not a mile from them the raft bobbing about on the waves as buoyant as a cork. It had, then, evidently survived the collision, but in the same glance they saw that it had no occupant.

Billy Barnes had vanished.

They spent the rest of the day till sunset circling about in the vain hope of coming across some trace of the missing lad; but in vain.

If the sea had indeed, as the boys now feared with sinking hearts, swallowed their young companion, he could not have vanished more completely.
