It was not a difficult thing for so many men to carry the whaleboat across the island, and they were disposed to make merry over the novelty of the task; but they had been instructed not to speak a loud word after the party left the south side of the island. The noise to which Christy and Flint had listened indicated that something was going on, though they could not decide what it was. In the stillness of the night, and in the absence of any roar of breakers, sounds could be heard a long distance, though whether they came one mile or two, they could not determine.

"Get out those cloths, Beeks," said Christy, as soon as the boat had been put into the water. "Every oar must be very carefully muffled, and you will see that it is properly done."

"I will have it done in a few minutes, sir," replied the acting coxswain.

213 "As I said before, we are in no hurry, and you may take your time to do it properly," added the lieutenant.

"Those sounds are still to be heard," said Flint, who had been a short distance from the boat to listen for them.

"I hear them," replied Christy, walking away from the boat to continue the investigation while they were waiting. "Some kind of a job is in progress at no great distance from us. From how far off do you calculate that those sounds come?"

"I think they must come a mile; and I don't believe I can guess any nearer to it than that, though it is possible they come two miles. I know little or nothing of the region about here. Suppose we should go a mile north-northeast from this spot, what should we find there, Mr. Passford?" asked Flint, apparently greatly interested in the question.

"It would be a point on Pensacola Bay, about half-way between this island, where we stand, and Town Point," replied Christy. "I should say it would be in the channel leading into Santa Rosa Sound."

"Precisely so!" exclaimed Flint, in an energetic 214 whisper. "That's the way they are going to take the Teaser out, and they are doing something over there to prepare her for the trip in shallow water."

The master's mate was not aware that Christy had suggested to the captain this way of escape for the Teaser, and he had abandoned the idea himself. Flint had reached his conclusion from his own premises. They discussed the matter for some time, though it was impossible to arrive at any conclusion for the want of data on which to base their reasoning.

"All ready, sir," reported Beeks, coming up to them at this moment.

"How far is the entrance to the sound from Fort Pickens, Mr. Passford?" asked Flint.

"About four miles."

"Then why should they choose such a night as this for their work?"

"The Bellevite, floating in four fathoms of water on the other side of the island, could shell them out if they were seen, as they certainly would be from Fort Pickens," replied Christy.

"That makes it plain enough," added Flint, as they walked towards the boat.

"But I am not quite willing to believe yet that 215 the Teaser will go out through the sound. If she could get through at all, it would only be after getting aground no end of times, and if to-morrow should be a clear day, she could be seen anywhere on her course," persisted Christy. "She cannot expect to make eight or ten knots an hour in that shallow water."

The lieutenant ordered the men into the boat, after she was shoved off the beach. They worked with such care that not a sound came from her. The oars were shipped, and the sailors began to row. As instructed, they pulled very slowly, though such work could not be done in perfect silence.

"Look out for that binnacle, Beeks," said Christy. "The light from it may betray us."

"You have not given me the course, sir," replied the coxswain, as he obeyed the order.

"North-northeast," added Christy, as he settled back in the stern sheets.

No one was allowed to speak in the boat, and the lieutenant set the example of silence. But he kept his ears wide open, though the little noise made by the oars and the rippling of the water prevented him from hearing anything at first. It 216 was so dark that one could hardly see another in the boat. It was in vain that Christy watched in the gloom for the glow of a light; for all was nearly total darkness in every direction.

In about half an hour they began to hear the sounds which had attracted their attention on the island, and they proceeded from directly ahead, indicating that the operations, whatever they were, came from the entrance to the sound. The workmen were not likely to hear the approach of the boat while they were making so much noise themselves. In addition to the sounds they had heard before, they recognized the noise of escaping steam.

This last discovery made it certain that a steamer was there, though the listeners could not know whether it was the Teaser or not. Both of the officers of the expedition, in the uselessness of their eyes, made the best use they could of their ears. Christy listened to ascertain if there was more than one steamer present. In a whisper he asked Flint to consider this question. There was no doubling of the sounds to indicate more than one steamer.

For ten minutes more Christy listened and was silent; but he was doing some very heavy thinking, 217 for by this time the boat was very near the scene of operations, if it could be a scene in that dense darkness. Every sound, even to the speech of the men, could be distinctly heard. Still nothing could be seen, and Christy knew that there was a............
