laden with auriferous earth, from his claim to
the river. Billy, rapidly gaining strength, was quite equal to the task,
but alas! not his inborn propensity. An incautious gesture from the
first passing miner Billy chose to construe into the usual challenge.
Lowering his head, from which his budding horns had been already pruned
by his master, he instantly went for his challenger, cart and all. Again
the scientific law already pointed out prevailed. With the shock of
the onset the entire contents of the cart arose and poured over the
astonished miner, burying him from sight. In any other but a Californian
mining-camp such a propensity in a draught animal would have been
condemned, on account of the damage and suffering it entailed, but in
Rocky Canyon it proved unprofitable to the owner from the very
amusement and interest it excited. Miners lay in wait for Billy with
a "greenhorn," or new-comer, whom they would put up to challenge the
animal by some indiscreet gesture. In this way hardly a cartload of
"pay-gravel" ever arrived safely at its destination, and the unfortunate
M'Ginnis was compelled to withdraw Billy as a beast of burden. It
was whispered that so great had his propensity become, under repeated
provocation, that M'Ginnis himself was no longer safe. Going ahead
of his cart one day to remove a fallen bough from the trail, Billy
construed the act of stooping into a playful challenge from his
master,--with the inevitable result.

The next day M'Ginnis appeared with a wheelbarrow, but without Billy.
From that day he was relegated to the rocky crags above the camp, from
whence he was only lured occasionally by the mischievous miners, who
wished to exhibit his peculiar performances. For although Billy had
ample food and sustenance among the crags, he had still a civilized
longing for posters; and whenever a circus, a concert, or a political
meeting was "billed" in the settlement, he was on hand while the paste
was yet fresh and succulent. In this way it was averred that he
once removed a gigantic theatre bill setting forth the charms of the
"Sacramento Pet," and being caught in the act by the advance agent, was
pursued through the main street, carrying the damp bill on his horns,
eventually affixing it, after his own peculiar fashion, on the back of
Judge Boompointer, who was standing in front of his own court-house.

In connection with the visits of this young lady another story
