over to see what you think of my house inside. Just follow me."

Paddy dived, and Jerry dived after him. He followed Paddy in at
one of the three doorways under water and up a smooth hall right
into the biggest, nicest bedroom Jerry had ever seen in all his
life. He just gasped in sheer surprise. He couldn't do anything
else. He couldn't find his tongue to say a word. Here he was in
this splendid great room up above the water, and he had been so
sure that there wasn't any room at all! He just didn't know what
to make of it.

Paddy's eyes twinkled. "Well," said he, "what do you think of
it?"

"I--I--think it is splendid, just perfectly splendid! But I don't
understand it at all, Cousin Paddy. I--I--Where is that great
pile of mud I helped you build in the middle?" Jerry looked as
foolish as he felt when he asked this.

"Why, I've dug it all away. That's what made the water so muddy,"
replied Paddy.

"But what did you build it for in the first place?" Jerry asked.

"Because I had to have something solid to rest my sticks against
while I was building my walls, of course," replied Paddy. When I
got the tops fastened together for a roof, they didn't need a
support any longer, and then I dug it away to make this room. I
couldn't have built such a big room any other way. I see you
don't know very much about house-building, Cousin Jerry."
