By the middle of August rabbits were noticeably less abundant
than they had heen a month earlier. Then, too, we began to find them
dead in the trails, evidently from some disease. It seemed apparent
that they were beginning to suffer from the ravages of the epidemic
that periodically reduces the northern rabbits, though from all
accounts their numbers locally had not yet reached the maximum that
was to be expected. This was but the second vear of increase since
the last period of searcity, we were told.
