"There they go!" bawled the farmer, lustily.

"Stop 'em!" Sam and Tom leaped to do as bidden.

Across the field dashed the horses, badly frightened by the noise, and in a few seconds they disappeared into the timber.
"Well, by gum! Now what's to be did ?" asked the farmer helplessly.
"Let's go after 'em!" answered Tom, running for the horse he had ridden.
"We ought to be able to catch them, Mr.Marley.Dick and Sam can stay here." "All right, we'll try it," answered the farmer.

"But them critters is powerful runners, I can tell ye thet! That black don't like no better fun than to run away." "Take care of yourself, Tom," called Dick, who had now stopped the engine.
