"I'll come over there and crook fingers on the bargain," said Ben, settling the rail and running over it to the tuft, then bridging another pool and crossing again till he came to the stump.

"I never thought of that way," said Sam, watching him with much inward chagrin at his own failure.

"I should think you'd written 'Look before you leap,' in your copy-book often enough to get the idea into your stupid head. Come, crook," commanded Ben, leaning forward with extended little finger. Sam obediently performed the ceremony, and then Ben sat astride one of the horns of the stump while the muddy Crusoe went slowly across the rail from point to point till he landed safely on the shore, when he turned about and asked with an ungrateful jeer,—

"Now what's going to become of you, old Look-before-you-leap?"

"Mud turtles can only sit on a stump and bawl till they are taken off, but frogs have legs worth something, and are not afraid of a little water," answered Ben, hopping away in an opposite direction, since the pools between him and Sam were too wide for even his lively legs.

Sam waddled off to the brook in the lane to rinse the mud from his nether man before facing his mother, and was just wringing himself out when Ben came up, breathless but good natured, for he felt that he had made an excellent bargain for himself and friends.

"Better wash your face; it's as speckled as a tiger-lily. Here's my handkerchief if yours is wet," he said, pulling out a dingy article which had evidently already done service as a towel.

"Don't want it," muttered Sam, gruffly, as he poured the water out of his muddy shoes.

"I was taught to say 'Thanky' when folks got me out of scrapes. But you never had much bringing up, though you do 'live in a house with a gambrel roof,'" retorted Ben, sarcastically quoting Sam's frequent boast; then he walked off, much disgusted with the ingratitude of man.

Sam forgot his manners, but he remembered his promise, and kept it so well that all the school wondered. No one could guess the secret of Ben's power over him, though it was evident that he had gained it in some sudden way, for at the least sign of Sam's former tricks Ben would crook his little finger and wag it warningly, or call out "Bulrushes!" and Sam subsided with reluctant submission, to the great amazement of his mates. When asked what it meant, Sa, turned sulky; but Ben had much fun out of it, assuring the other boys that those were the signs and password of a secret society to which he and Sam belonged, and promised to tell them all about it if Sam would give him leave, which, of course, he would not.
