"Oh, yes, first rate. But we can't go any farther."

"Can't go any farther? What's the matter, did your boat sink?"

"No, but we're stuck in Lemby Creek. Mr. Hardee, a farmer who owns land on both sides of the creek, has put a wire fence across to stop us from going on to Lake Romano."

"Is that so! Well, that's too bad. How did it happen?"

"I'll tell you," said Mr. Bobbsey.

Then he told the story of stopping the angry farmer from beating Will Watson, and how the fence had been built in the night.

"Well, that certainly was a mean trick on the part of Mr. Hardee,"

said Mr. Murphy. "And so the boy ran away?"

"Yes, and Mr. Hardee accused me of knowing something about him, but I don't--any more than you do."

"I suppose not. But now the question is, How are you going to get past that wire fence?"

"I don't know. The only way I see is to get Mr. Hardee to cut it, or take it down, and he says he won't do either."

"Humph! Let me see. There ought to be a way out of it. I believe he has the right, as far as the law goes, to put that fence up, but no one else would be so mean. I guess we'll just have to force him to cut those wires, as your little boy, Freddie, suggested."

"Yes, but how can we do it?" asked Mr. Bobbsey. "Mr. Hardee is very headstrong, and set in his ways."

"Let me see," spoke Mr. Murphy slowly, "isn't his name Jake Hardee?"

"Yes, I believe it is."

"And didn't he buy from you the lumber to build his house?"

"Yes, I sold him the lumber, but he paid me for it," said Mr. Bobbsey.

"I couldn't get any hold on him that way. He paid for the lumber in cash."

"Yes," cried Mr. Murphy, "but he got the money from me to pay you, and he hasn't paid ME back. He still owes ME the money, and he gave me a mortgage on his house as security. I've got a hold on him all right.

He owes me some interest money, too."

I might say to you little children that when a man wants to build a house and has not enough money, he goes to another man and borrows cash, just as your mamma sometimes borrows sugar, or tea, from the lady next door.

When the man borrows money to build his house, he gives to the man who lends him the cash, a piece of paper, called a mortgage. That paper says that if the man who borrowed the money does not pay it back, and also pay interest for the use of it, the man who lent him the money can take the house. The house is "security" for the loaned money.

It is just as if your mamma went next door to borrow a cup of sugar, and said:

"Now, Mrs. Jones, if I don't pay you back this sugar, and a little more than you gave me, for being so kind as to lend it to me--if I don't pay it back in a week, why you can keep my new Sunday hat." And your mamma might give Mrs. Jones a Sunday hat as "security" for the cup of sugar. Of course ladies do not do those things, but that is what a mortgage is like.

"Yes." said Mr. Murphy to Mr. Bobbsey, "Mr. Hardee borrowed from me the money to buy from you the lumber for his house. And he hasn't paid me back the money, nor any interest on it. I think I'll go up and have a talk with him. And, when I get through talking, I guess he'll let you go through his wire fence."

"I hope he will," said Mr. Bobbsey, "for it would be too bad to have our trip spoiled."

"I'll go right back with you," offered Mr. Murphy.

So it happened that Mr. Bobbsey, with his friend, reached the houseboat, in Lemby Creek, shortly after dinner.

"Oh, back so soon?" asked Mrs. Bobbsey. "What are you going to do, Mr.

Murphy?"

"Have a talk with Mr. Hardee."

Mr. Bobbsey and Mr. Murphy walked down the bank of the creek to the farm. They found Mr. Hardee mending a broken harness.

"Mr. Hardee," said Mr. Murphy, "I hear you have put a wire fence across Lemby Creek, so my friend, Mr. Bobbsey, can't get past with his houseboat."

"Yes, I have," growled the farmer, "and that fence is going to stay up, too! I'll show him he can't come around here, interferin' with me when I try to punish my help. He made Will run away too."

"No, I did not. I know nothing of him," said Mr. Bobbsey.

"Mr. Hardee," went on Mr. Murphy. "I want you to take down that fence, and let the houseboat go on up the creek."

"And I'm not going to!"

"Very well, then," said Mr. Murphy, quietly, "perhaps you are ready to pay me the interest on my mortgage which has been due me for some time, Mr. Hardee."

The farmer seemed uneasy.

"Well, to tell you the truth," he said, "I haven't got that money just now, Mr. Murphy. Times have been hard, and crops are poor, and I'm short of cash. Can't you wait a while?"

"I have waited some time."

"Well, I'd like to have you wait a little longer. I'll pay you after a while."

"And I suppose you'll take down that wire fence, and let Mr. Bobbsey and the twins go past--after a while?"

"Well--maybe," growled the mean farmer.

"Maybe won't do!" exclaimed Mr. Murphy. "I want you to take the wire fence down RIGHT AWAY."

"Well, I'm not going to do it. He interfered with me, and made that boy run away, and I'm not going to let him go up my part of the creek."

"Well, then, Mr. Hardee, if you can't do something for Mr. Bobbsey, as a favor, I can't do anything to oblige you. Mr. Bobbsey is a friend of mine and unless you cut your wire fence, I'll have to foreclose that mortgage, and take your house in payment for the money you owe me.

That's all there is about it. Either pay me my money--or cut that fence. It must be one or the other."

Mr. Hardee squirmed in his seat, and seemed very uneasy.

"I--I just can't pay that money," he said.

"Then I'll have to take your house away."

"I--I don't want you to do that, either."
