Luckily the line was just where the farmer supposed it would be, and away went man and boy, Dick leading, until the river bank was again reached.

“There he is, Mr. Darrel.  How can we best help him, do you think?”

The farmer scratched his head in perplexity.

“Hang me if I jess know, Dick,” he said slowly.

“If we try to pull him straight to shore the current will carry him over the rocks in spite of the line.”

“How long do you suppose the line is?”

“It is fifty yards, and all good and strong, for I bought it of Woddie only last week.”

“Fifty yards —­ that is a hundred and fifty feet.  Do you see that spur of rock just above there?”

“I do.”

“Is it more than a hundred and fifty feet from that rock to the tree?”

“Hardly; but it’s close figuring.”

“Let us try the line and see.”

Both walked up to the spur of rock they had in view.  It jutted out into the river for several yards, and was rather wet and slippery.

“Take care, or you’ll go in too,” cautioned Joel Darrel.  “Shall I throw the rope out?”

“You might try it,” answered Dick.  “I’ll hold fast to your leg,” and he squatted down for that purpose.

The line was uncoiled and thrown three times, but each time it fell short and drifted inshore again.

“Hurry up!” suddenly yelled Sam.  “The tree is beginning to turn, and it will break loose before long.”

“Let me try a throw,” said Dick, and took the wash line.  As he made the cast, Tom came up on a walk, his head tied up in a handkerchief.

“Where is Sam?”

“Out there,” said Joel Darrel, and watched the casting of the line with interest.  Again it fell short, but Dick’s second throw was a complete success, and soon Sam held the outer end of the line fast.

“It reaches, and we have about fifteen feet to spare,” said Dick joyfully.  “Sam, tie it around you.”  Scarcely had the word left the younger brother’s lips than the tree upon which he rested wobbled and went over, and he found himself thrown into the foaming water.

“Pull away, all hands!” cried Dick, and hauled in desperately, while Joel Darrel did the same.  Tom was not equal to the task, but contented himself with holding fast to Dick’s coat, that his elder brother might not slip from the rock.

It was no light work to get Sam up the first rise of the rapids, but once this rise was passed the rest was easy by comparison.  They pulled in steadily, and presently the boy reached the rock and came up, looking very much like a dripping seal as he clambered to safety.

“Thank fortune, you are safe!” cried Dick when it was all over; and Tom said “Amen,” under his breath.  Joel Darrel looked well satisfied as he coiled up the wash line.

“It was a narrow escape,” he remarked presently.  “You want to be careful how you try to cross the river at this point.  What were you doing on the tree?”
