Dick joined because it afforded him an opportunity of
seeing the wild, majestic scenery of the Rocky Mountains,
and shooting the big-horned sheep which abounded
there, and the grizzly "bars," as Joe named them, or
"Caleb," as they were more frequently styled by Henri
and the other men.
Henri joined because it was agreeable to the inclination
of his own rollicking, blundering, floundering, crashing
disposition, and because he would have joined anything
that had been joined by the other two.
