telling them that this was simply a squall, and would soon blow itself out, and that there was nothing to be feared.

The howling of the gale, the creaking and straining of the shrouds, the thumping and pounding and groaning of the machinery, and the tramping of men overhead made a combination of sounds that might well terrify anyone, and the older boys tried to reassure the younger ones that it would be over in a short time, and that they would soon be sailing on smooth seas again, and be laughing at their former terrors, but it took a great deal of faith to make all this believed, and some of those who urged it had very little confidence in its truth.

Herring, Merritt, and others of the same class were really terrified, and took on dreadfully, predicting all sorts of dreadful things, and declared that they were fools to have taken this voyage, and that they would never undertake another.

Jack Sheldon, Dick Percival, Harry Dickson, and even mercurial Billy Manners were quite different, however, and young Jesse W. Smith acted like a man, and although he was frightened, as any one might be, and no shame to him, did not give way to his fright, but said very wisely that he guessed the storm had been gotten up for their especial benefit so that they might know what sort of things they could do in these latitudes.

How long they were rushing before wind and sea they did not know, for it seemed ages, where they were going they could not guess either as they had come from an unexpected quarter, and so suddenly that they had not noticed its direction, and were not where they could look at the compass.

All was bright and cheerful in the cabins, but through the portholes they could see that all was dark outside with an occasional vivid flash of lightning, these coming less and less frequent at length till they ceased, and then the skies began to brighten.

Suddenly, however, before it was yet bright enough outside to make out any objects, there was a sudden rush forward as if they had been struck by a great wave, then a sudden upheaving as if they were mounting to the sky, then another long rush forward, and then a shock as if they had struck something, and for a few moments the lights went out.

When they flared up again the vessel seemed to be at anchor, and the boys said to each other:

"What is the matter, have we struck on a rock, are we sinking, what is the matter anyhow?"

There was no confusion on deck, as there would have been if what the boys feared had really happened, and presently one of the officers came below and said reassuringly:

"Well, we are all right as far as I can see, but where we are is another story. In some landlocked bay, apparently, but where it is or how we reached it I can't tell."

"We were struck by a cyclone, weren't we, Officer?" asked young Smith, with a wise air.

"That's just what it was, and when those things strike you they strike hard. Lucky for us that we happened to be going ahead of it, for if we had been head on to it we might not have survived."

"But there is no danger, we have not struck a rock or anything, we have no holes in our hull?"

"None that we can see. We are beached somewhere, and we may slide into deeper water, but as far as we can tell now we are safe enough. Where we are, however, will have to be determined when the sun comes out."

The boys were reassured by this news, and after a time some of them went out on deck, the yacht being now almost motionless, the waves just lapping their sides, and running lazily up a beach, which they could now just make out at a little distance.

It grew lighter and lighter quite rapidly, and at length the sun appeared, and they found themselves in a landlocked bay with a white beach in front of them, beyond that a thick grove of palms of various kinds, green hills on all sides and in the distance, straight ahead, a hill of considerable size crowned with a thick growth of trees.

As the sun grew brighter the scene increased in attractiveness, and the greater part of the boys were charmed by it, making many exclamations of delight, as they turned from one object to another.

"It's a fine place wherever it is," said Jack. "I suppose they will locate it to-morrow, and perhaps some one will come out to the yacht, and tell us where we are."

"I don't see any sign of dwellings," murmured Percival. "Perhaps there are no people on it. Not all of these little islands are inhabited, and I suppose it is an island?"

"Probably, for I do not think we are near the South American coast. Some one will know after a bit, doubtless. At any rate, we are safe and that is a good deal."

One of the officers came along where the two boys were standing, and Jack asked him if he knew where they were.

"No, I don't," was the answer. "We have not been able to get an observation yet, and we started off at such a gait that it was impossible to tell where we were going or at what rate. We will probably locate ourselves in the morning, but there is no danger so you can make your minds easy on that point, young gentlemen."

"There is a good deal in that, sir," said both boys.

CHAPTER IV

CAUGHT ON LOST ISLAND

The sun set gloriously, and after a short twilight common to those latitudes the full moon arose over the hills, and all the stars came out little by little till the heavens were full of them.

The moon dimmed their brightness somewhat, but they were still very brilliant, and the night was a glorious one, the air warm and balmy, the breeze just enough to temper the heat of the air, and all around them sea and shore bathed in moonlight.

After dinner, which was served in the saloon as usual, the boys went out on deck for the most part, and enjoyed the beautiful evening, being dispersed in little groups here and there, some seated and some walking the decks.

"We are safe enough, anyhow," observed Jack to Percival and a few of the boys who were seated on deck with him, "and I suppose we will not leave here till the morning at any rate."

"We are sheltered in this bay, and even if there should be a storm outside we will not feel it," returned Percival. "I hardly think there is one, and it seems strange that we should have caught that cyclone at this time of the year. Isn't it unusual?"

"You can't call anything unusual in the tropics," laughed Jack. "I believe you are liable to catch anything at any time here from yellow fever to a tornado. They seem to have them always on hand."

"Well, we are safe now, at any rate, and I am glad for that much. We will make the best of this fine night, and take other things as they come."

It was late when the last of the boys went to bed, for they all wanted to make the most of the fine night, but they were all up early the next morning, anxious to learn where they were, and if they would stay at the island or put to sea again.

Jack was the first of the boys on deck, and when he reached there he saw Dr. Wise talking to the captain and the first officer, there being a grizzled old seaman conversing with Bucephalus at a short distance.

The doctor and the officers seemed to be carrying on a very earnest conversation, and Jack heard a little of it as he came forward, and then suddenly stopped, fearing that he might be intruding.

"We are on the bottom, sir, and I don't know how long we may be there," said Captain Storms. "The next high tide may raise us, and it may not. It is my opinion that we have been on the bottom ever since we came into the bay, and how we are going to lighten her I don't know."

"But there are no holes, we have opened no seams, we have not taken in any water?" asked the doctor, looking fixedly at the captain through his big black-rimmed spectacles.

"No, there are no open seams and no water. The bottom is sandy, too, I think, and not the sharp coral rock you find in these parts that will cut a hole in anything that touches
