But they were glad eyes, which began to make an appeal.

Presently, when Wade came to a rough place, the dog slipped under a shelving rock, and thence through a half-concealed hole in the fence; and immediately came back through to wag his stump of a tail and look as if the finding of that hole was easy enough.
"You old fox," declared Wade, very much pleased, as he patted the dog.
"You found it for me, didn't you?
Good dog! Now I'll fix that hole, an' then you can come to the cabin with me.

An' your name's Fox." That was how Fox introduced himself to Wade, and found his opportunity.
The fact that he was not a hound had operated against his being taken out hunting, and therefore little or no attention had been paid him.
Very shortly Fox showed himself to be a dog of superior intelligence.
The hunter had lived much with dogs and had come to learn that the longer he lived with them the more there was to marvel at and love.
Fox insisted so strongly on being taken out to hunt with the hounds that Wade, vowing not to be surprised at anything, let him go.

It happened to be a particularly hard day on hounds because of old tracks and cross-tracks and difficult ground.

Fox worked out a labyrinthine trail that Sampson gave up and Jim failed on.
