They brought cattle, sheep, goats, and dogs; why not the horse, the delight of savage hordes?
Horses thrive well in the Cape Colony when imported.

Naturalists point out certain mountain ranges as limiting the habitat of certain classes of animals; but there is no Cordillera in Africa to answer that purpose, there being no visible barrier between the northeastern Arabs and the Hottentot tribes to prevent the different hordes, as they felt their way southward, from indulging their taste for the possession of this noble animal.
I am here led to notice an invisible barrier, more insurmountable than mountain ranges, but which is not opposed to the southern progress of cattle, goats, and sheep.

The tsetse would prove a barrier only until its well-defined habitat was known, but the disease passing under the term of horse-sickness (peripneumonia) exists in such virulence over nearly seven degrees of latitude that no precaution would be sufficient to save these animals.

The horse is so liable to this disease, that only by great care in stabling can he be kept any where between 20 Deg.
and 27 Deg.
