endure had the llama and alpaca not existed, for their cogeners, the
huanacu and the vicuna, are hardly to be domesticated.

Zebras, speaking broadly, are unmanageable. The Dutch Boers
constantly endeavour to break them to harness, and though they
occasionally succeed to a degree, the wild mulish nature of the
animal is always breaking out, and liable to balk them.

It is certain that some animals have naturally a greater fondness
for man than others; and as a proof of this, I will again quote
Hearne about the moose, who are considered by him to be the easiest
to tame and domesticate of any of the deer tribe. Formerly the
closely-allied European elks were domesticated in Sweden, and used
to draw sledges, as they are now occasionally in Canada; but they
have been obsolete for many years. Hearne says:--

"The young ones are so simple that I remember to have seen an Indian
paddle his canoe up to one of them, and take it by the poll, without
experiencing the least opposition, the poor harmless animal seeming
at the same time as contented alongside the canoe as if swimming by
the side of its dam, and looking up in our faces with the same
fearless innocence that a house lamb would."

On the other hand, a young bison will try to dash out its brains
against the tree to which it is tied, in terror and hatred of its
captors.

It is interesting to note the causes that conduce to a decided
attachment of certain animals to man, or between one kind of animal
and another. It is notorious that attachments and aversions exist in
nature. Swallows, rooks, and storks frequent dwelling houses;
ostriches and zebras herd together; so do bisons and elks. On the
other hand, deer and sheep, which are both gregarious, and both eat
the same food and graze within the same enclosure, avoid one another.
The spotted Danish dog, the Spitz dog, and the cat, have all a
strong attachment to horses, and horses seem pleased with their
company; but dogs and cats are proverbially discordant. I presume
that two species of animals do not consider one another companionable,
or clubable, unless their behaviour and their persons are
reciprocally agreeable. A phlegmatic animal would be exceedingly
disquieted by the close companionship of an excitable one. The
movements of one beast may have a character that is unpleasing to
the eyes of another; his cries may sound discordant; his smell may
be repulsive. Two herds of animals would hardly intermingle, unless
