"What're you a goin' to town this time o' night for?" asked Sid Russell, who was strongly prejudiced against staying awake a moment later than was necessary after the sun went down.

"I've laid some plans to get some information," replied Sam, "and I'm going after it," and with that he jumped into the boat, with only Tom for company. In truth, Sam had been in search of the information that he was going after for several days, and he had reason to hope that he might get it on this particular night.

He had already learned that several of the British vessels, now lying in the bay, had sailed away some little time before, and that they had returned on the night before Bob's arrival. He knew that their voyage must have had some connection with the plans they had laid for operations against the American coast, and he thought if he could discover the nature and purpose of this recent expedition, it would give him a clew to their projects for the future. To accomplish this he had taken many risks while the ships were away, and he was now going to try a new way of getting at facts.

He sailed his boat up to the town, and before landing, said to Tom:—

"When I'm ashore, you put off a little way from land and lie-to for an hour or so. When I want you, I'll come down here to the water's edge and whistle like a Whip-Will's Widow. When you hear me, run ashore. If I don't come by midnight, go back to camp, and march at once for Mobile."

"Why can't I lie here by the shore till you come. You're going into danger and may need me."

"First, because there are ruffians around here who might put you ashore and steal the boat; but secondly, because I don't want to excite suspicion by having our boat seen around here at night. It's so dark that nobody can recognize her if you lie-to a hundred yards from shore. I'm going into danger, but you can't help me."

Avoiding further parley, Sam jumped ashore, and walked quietly up into the town, through the main street, until he came to a house built after the Spanish model, with a rickety stair-way outside. Up this stair-way he climbed, and when he had reached the top he pushed the door open and entered. He found himself in a dark passage, but by feeling he presently discovered a door. As he opened it he said:—

"It's a dark night."

"Is it dark?" answered a voice from within.
