“Could you help us to escape?” asked the child.

“Why, I don’t know how,” admitted Cap’n Joe.  “There’s magic all around us, and we slaves are never allowed to leave this great cave.  I’ll do what I can, o’ course, but Sacho is the boy to help you if anyone can.  That little chap knows a heap, I can tell you.  So now, if nothin’ more’s wanted, I must get back to work.”

“What work do you do?” Cap’n Bill asked.

“I sew buttons on Zog’s clothes.  Every time he gets mad, he busts his buttons off, an’ I have to sew ’em on again.  As he’s mad most o’ the time, it keeps me busy.”

“I’ll see you again, won’t I, Joe?” said Cap’n Bill.

“No reason why you shouldn’t, if you manage to keep alive,” said Cap’n Joe.  “But you mustn’t forget, Bill, this Zog has his grip on you, an’ I’ve never known anything to escape him yet.”

Saying this, the old sailor began to stump toward the door, but tripped his foot against his wooden leg and gave a swift dive forward.  He would have fallen flat had he not grabbed the drapery at the doorway and saved himself by holding fast to it with both hands.  Even then he rolled and twisted so awkwardly before he could get upon his legs that Trot had to laugh outright at his antics.  “This hick’ry leg,” said Cap’n Joe, “is so blamed light that it always wants to float.  Agga-Groo, the goldworker, has promised me a gold leg that will stay down, but he never has time to make it.  You’re mighty lucky, Bill, to have a merman’s tail instead o’ legs.”

“I guess I am, Joe,” replied Cap’n Bill, “for in such a wet country the fishes have the best of it.  But I ain’t sure I’d like this sort o’ thing always.”

“Think o’ the money you’d make in a side show,” said Cap’n Joe with his funny chuckling laugh.  Then he pounded his wooden leg against the hard floor and managed to hobble from the room without more accidents.

When he had gone, Trot said, “Aren’t you glad to find your brother again, Cap’n Bill?”

“Why, so-so,” replied the sailor.  “I don’t know much about Joe, seein’ as we haven’t met before for many a long year, an’ all I remember about our boyhood days is that we fit an’ pulled hair most o’ the time.  But what worries me most is Joe’s lookin’ so much like me myself, wooden leg an’ all.  Don’t you think it’s rather cheeky an’ unbrotherly, Trot?”

“Perhaps he can’t help it,” suggested the child.  “And anyhow, he’ll never be able to live on land again.”

“No,” said Cap’n Bill with a sigh.  “Joe’s a fish, now, an’ so he ain’t likely to be took for me by one of our friends on the earth.”

THE MAGIC OF THE MERMAIDS

CHAPTER 15

When Trot and Cap’n Bill entered the Rose Chamber they found the two mermaids reclining before an air fountain that was sending thousands of tiny bubbles up through the water.
