CHAPTER IV.
_Our hero enlarged upon--Grumps_.
Two years passed away.

The Mustang Valley settlement advanced prosperously, despite one or two attacks made upon it by the savages, who were, however, firmly repelled.

Dick Varley had now become a man, and his pup Crusoe had become a full-grown dog.

The "silver rifle," as Dick's weapon had come to be named, was well known among the hunters and the Redskins of the border-lands, and in Dick's hands its bullets were as deadly as its owner's eye was quick and true.
Crusoe's education, too, had been completed.

Faithfully and patiently had his young master trained his mind, until he fitted him to be a meet companion in the hunt.
