On the islands, especially, different kinds are found.

The wood-dogs will occasionally, in calm weather, swim out to an island and kill every sheep upon it.
From the horses that were in use among the ancients the two wild species now found are known to have descended, a fact confirmed by their evident resemblance to the horses we still retain.

The largest wild horse is almost black, or inclined to a dark colour, somewhat less in size than our present waggon horses, but of the same heavy make.

It is, however, much swifter, on account of having enjoyed liberty for so long.

It is called the bush-horse, being generally distributed among thickets and meadow-like lands adjoining water.
The other species is called the hill-pony, from its habitat, the hills, and is rather less in size than our riding-horse.
