"Oh, how glad I am to see you alive!" cried Andy, when the pair were safe.

"And I am glad, too, cap'n," put in George Dross. "I never expected to set eyes on ye ag'in."

"But how did the Holland escape?" asked the young captain.

"The explosion set us free," answered Andy. "But we had to move out lively, or we would have been crushed as flat as a pancake when the wreckage came down a second time."

Captain Oscar was now asked to tell his own story and did so. He was very weak, but a good dinner with a strong cup of coffee soon made him feel once more like himself.

"What's orders?" asked Andy, coming in the dining-room while he was eating.

"We must attack that Japanese army," answered the young captain. "They are marching for Havana, with the intention of invading Florida."

"And how are you going to do it?"

"They are marching forward in almost a solid body. As soon as they form, we will rise to the surface and throw a couple of dynamite bombs into their midst."

Orders were at once delivered to the ammunition men and the bombs were brought forth and inspected, to see that they were ready for use.
