He had done more than this, for he had brought out a couple of guns and a section of artillerists to beat off the guard-boat if it interfered with the operations of the navy.
Christy had taken a course from the entrance of the sound, half way between the island and Town Point, west-southwest.

He knew that the distance was about four miles; but he could not know, except by sounding, when he came to the island, and he had bargained with the army officer to be on the lookout for him.

Captain Westover had heard the noise of the Teaser, and had hailed her, thus assuring the lieutenant that his calculation had been correct, and that he was in the vicinity of Fort Pickens.
"I had no idea that you would accomplish anything, lieutenant," said Captain Westover.
"I found everything laid out just as I should have wished it to be," replied Christy.

"We had plenty of information that the steamer would run out the first favorable night; and nothing could have been more favorable for blockade running than this fog and darkness." "But nothing has been seen of this steamer from the fort." "Where was she fitted out, Dave ?" asked Christy, turning to the steward.
"Up by Emanuel Point, sir, about a mile above the town," replied Dave.
"Then she has not shown herself in the lower bay." The conversation was interrupted by the roll of a drum on the shore.
"There you are, lieutenant," said the captain with a smile.

"When you are ready to go ahead, don't wait on my account, for I will go on board of the ship." "But what is the drum for ?" asked the lieutenant, who was in the dark in his turn.
"I am not much of a sailor, lieutenant, but I have sent a drummer to follow the shore to the west end of the island, and you will know by the racket he makes where the island is, and how far off it is," replied the army officer.
"I am much obliged to you, Captain Westover; that will be a safe guide for me," said Christy, as he rang to go ahead.
He gave out the course west by north, and he thought he should be able to keep within hail of the island, though, as he could see nothing, it would be difficult to tell when he reached the northwest corner of it.
