"The game is up," the skipper said. "They will be alongside in a few minutes. Dark as it is they cannot miss us. They will know that we must have drifted straight down. We must take to the boats and row for it."

"I should say, captain," Ned said, "we had best take to the boat and row off for a short distance, and then wait. As likely as not they may think when they board her that she has simply drifted out from the town, having been carelessly moored. In that case they may let drop her anchor and return to their ship."

"That is a happy thought," the captain said; and running forward he told the crew to take the boat at once.

"I have another idea, captain," Ned said, just as they were about to push off. "As we saw when we were passing the ship we are drifting stern foremost. If we can fasten a long line to her stern we can hang on to it. They will not be able to see us if we are twenty fathoms astern. Then, if they anchor, and, as is likely enough, leave two or three men on board, we can haul ourselves noiselessly up with the rope and board her."

"Capital!" the captain replied. "I was wondering how we should find her again in the dark. That would be the very thing."

He sprang on board again, fastened a light line to the rudder, and dropped down into the boat again.

"Now, back her astern, lads, very gently. I can hear their oars."

In a minute the captain gave orders to cease rowing, for the line had tightened. The Spanish ship was showing a bright light in her stern. This acted as a guide to the boats, and in two or three minutes after the crew had left the smack two large boats full of soldiers came alongside. Those in the little boat, lying but fifty or sixty yards away, could hear every word that was spoken. First came a volley of angry exclamations of disappointment as the Spaniards found that they had been called from their beds only to capture an empty little coaster. As Ned had expected, they speedily came to the conclusion that having been carelessly fastened up alongside the wharves, without any one being left in charge, she had drifted out with the tide.

"It would serve them right if we were to set her alight," one of the officers said.

"We had best not to do that," another replied. "It might cause an alarm in the town; and, besides, boats are wanted. We had better drop her anchor, and leave four men on board to take care of her. In the morning the knaves to whom she belongs will come out to claim her; and I warrant you the captain will punish them sharply for the trouble they have given us."
