A new influence appears on the scene; it is
commonly called the plague, though it is not one disease but many
run epidemic riot, and, in a few weeks usually, the Rabbits are
wiped out.
This is an outline of the established routine in Rabbit vital
statistics. It, of course, varies greatly in every detail, including
time and extent of territory involved, and when the destruction is
complete it is an awful thing for the carnivores that have lived
on the bunny millions and multiplied in ratio with their abundance.
Of all the northern creatures none are more dependent on the Rabbits
than is the Canada Lynx. It lives on Rabbits, follows the Rabbits,
thinks Rabbits, tastes like Rabbits, increases with them, and on
their failure dies of starvation in the unrabbited woods.
It must have been a Hibernian familiar with the north that said:
"A Lynx is nothing but an animated Rabbit anyway."
The Rabbits of the Mackenzie River Valley reached their flood
height in the winter of 1903-4. That season, it seems, they actually
reached billions.
Late the same winter the plague appeared, but did not take them at
one final swoop. Next winter they were still numerous, but in 1907
there seemed not one Rabbit left alive in the country. All that
summer we sought for them and inquired for them. We saw signs of
millions in the season gone by; everywhere were acres of saplings
barked at the snow-line; the floor of the woods, in all parts visited,
was pebbled over with pellets; but we saw not one Woodrabbit and
heard only a vague report of 3 that an Indian claimed he had seen
in a remote part of the region late in the fall.
