Glad to know that he had found, not only so many kind friends, but
also several rich relatives, Dave went back again to Oak Hall. His
classmates were more than glad to see him, but others were jealous of
his success in life, and several of his enemies, including a certain
Link Merwell, did all they could to annoy him. The annoyances went
from bad to worse, and in the end one boy named Jasniff ran away from
school, and the other, Merwell, was expelled.

Dave's sister Laura had a friend, Belle Endicott, who lived in the Far
West, and through this young lady Dave and his chums and also Laura
and Jessie received an invitation to spend some time at the Endicott
place, known as Star Ranch. While in the West Dave once more fell in
with Link Merwell, and this young man, as before, tried to make

returning once again to Oak Hall. But this was not to be, for Merwell

other, Link Merwell, managed to make his escape.

During Dave's next term at school there was much trouble with one of
the teachers, who was harsh and unsympathetic, and as a result some of
the boys ran away. It was Dave who went after them and who, in spite
of a fearful flood, managed to bring them back and make them face the
music. Then came the graduation exercises at Oak Hall, Dave receiving
high honors.

Our hero had promised Roger Morr that he would pay the senator's son a
visit. During this time Dave heard of a gold mine belonging to Mrs.
Morr which had been lost because of a landslide. All the boys went out
West in an endeavor to relocate this claim. Their adventures were both
numerous and hazardous, and once more Dave fell in with Link Merwell.
But all went well with our young friends, and they had a glorious
