"But the big four came back safe and sound, and brought the enemy with them."

"You were all plucky, and I believe you never fail to get the better of all enemies in whatever form they come."

"Now, beloved commander of the Guardian-Mother, can you tell me what possible chance there is for an adventure in the excursion we have arranged?" asked Louis, rather more seriously.

"If you should undertake to capture the Rock of Gibraltar, it will be well for you to know that it is garrisoned by about five thousand soldiers of all arms; and that number of full-grown men are too many for even the big four," continued the commander, not disposed to be serious.

"The big four don't mind five thousand soldiers; if there were ten thousand of them, we might hesitate."

"Perhaps you will prefer to pick up the entire Rock and drop it into the bay; but the water is not deep enough to cover up the highest points of it, and somebody might find out what you had been about."

"Now, Captain, could you be reasonably serious for a moment, only long enough to guess the conundrum I put to you just now?" asked Louis.

"I might try. What was the conundrum?" asked the commander, smoothing off his face.

"If my mother knew I was going ashore, or off in a boat, she would immediately conclude that I was to be shot, pitched over a precipice, or sunk to the bottom of the bay with a fifty-six tied around my neck."

"Formerly she would; but Dr. Hawkes has wonderfully improved her nervous system, so that she would not conclude that anything of the sort would happen to you. You have got into so many scrapes and always come out of them without the singeing of a hair of your head, that she has acquired some confidence in your happy destiny," replied the captain.
