Then having piled the three on the fourth, he scattered filth over
them to express his utter contempt for my devices. After this he
left my drag and went about his business with the pack he guarded
so effectively.

This is only one of many similar experiences which convinced me
that poison would never avail to destroy this robber, and though I
continued to use it while awaiting the arrival of the traps, it was
only because it was meanwhile a sure means of killing many
prairie wolves and other destructive vermin.

About this time there came under my observation an incident that
will illustrate Lobo's diabolic cunning. These wolves had at least
one pursuit which was merely an amusement; it was stampeding
and killing sheep, though they rarely ate them. The sheep are
usually kept in flocks of from one thousand to three thousand
under one or more shepherds. At night they are gathered in the
most sheltered place available, and a herdsman sleeps on each side
of the flock to give additional protection. Sheep are such senseless
creatures that they are liable to be stampeded by the veriest trifle,
but they have deeply ingrained in their nature one, and perhaps
only one, strong weakness, namely, to follow their leader. And this
the shepherds turn to good account by putting half a dozen goats in
the flock of sheep. The latter recognize the superior intelligence of
their bearded cousins, and when a night alarm occurs they crowd
around them, and usually are thus saved from a stampede and are
easily protected. But it was not always so. One night late in last
November, two Perico shepherds were aroused by an onset of
wolves. Their flocks huddled around the goats, which, being
neither fools nor cowards, stood their ground and were bravely
