"The bottom is sandy, and we shall take the ground before we reach the shore if we don't manage properly. But we can tell something by the mangroves that fringe the land," replied the pilot; "and I will go into the bow of the cutter and look out for them."

Mr. Amblen made his way to the fore sheets, and asked Boxie, who was there, for the boathook, with which he proceeded to sound. When he had done so, he raised both his hands to a level with his shoulders, which was the signal to go ahead, and the men pulled a very slow stroke. He continued to sound, after he had selected the point for landing.

When the first cutter was within three lengths of the shore, he elevated both his hands above his head, which was the signal to cease rowing, though the two bow oarsmen kept their oars in the water instead of boating them as the others did. Mr. Amblen continued to feel the way, and in a few minutes more, aided by the shoving of the two bow oarsmen, he brought the boat to the shore.

Then he gave his attention to the second cutter, bringing it to the land alongside of the first. Stepping out on the sand himself, he was followed by all the crew, with cutlass in hand, and revolvers in readiness for use. The men were placed in order for an advance, and then required to lie down on the sand, so that they could not readily be seen if any stroller appeared on the ground.

Leaving the force in charge of Mr. Flint, Christy and Amblen walked towards the battery, crouching behind such objects as they could find that would conceal them in whole or in part. The earthwork was semicircular in form, and was hardly more than a rifle pit. No sentinel could be discovered, and getting down upon the sand, the two officers crept cautiously towards the heaps of sand which formed the fort.

Christy climbed up the slope with some difficulty, for the dry sand afforded a very weak foothold. On the top of it, which was about six feet wide, they found a solid path which had evidently been a promenade for sentinels or other persons. Behind it, on a wooden platform, were four field guns, with depressions in the earthwork in front of the muzzles.

Christy led the way down the slope on the inside to the pieces, which were twelve-pounders. At a little distance from the platform was a sort of casemate, which might have been constructed for a magazine, or for a place of resort for the gunners if the fort should be bombarded. Not a man could be seen, and if there was any garrison for the place, they were certainly taking things very comfortably, for they must have been asleep at this unseemly hour for any ordinary occupation.

Not far from the battery was a rude structure, hardly better than a shanty, which Christy concluded must be the barracks of the soldiers if there were any there. He walked over to it; but there was not a human being to be seen in the vicinity. It was half past one at night, when honest people ought to be abed and asleep, and the first lieutenant of the Bronx concluded that the garrison, if this shanty was their quarters, must be honest people.

Christy walked very cautiously to the side of the building, for the entrance was at the end nearest to the fort, and found several windows there, from which the sashes seemed to have been removed, if there had ever been any. The bottom of each opening was no higher than his head, and he went to one of them and looked in.

Extending along the middle of the interior was a row of berths. It was very dark inside, and he could not make out whether or not these bunks were occupied. The windows on the other side of the shanty enabled him to see that there were two rows of berths, each backing against the other. There were two in each tier, and he judged that the barrack would accommodate forty-eight men.
