Here is the home of the horse, the ass, and many varieties of oxen,
sheep, and goats,--those animals which, domesticated by man, have
accompanied him to all climes, adapting themselves to all circumstances.
The American turkey, the European pheasant, and the Asiatic parents of
many of our domestic fowls, also belong to the temperate zone; together
with a multitude of song birds, whose sober plumage, contrasting so
gloomily with the brilliant colors of their neighbors of the tropics, is
compensated by the sweetness of their notes. Here, also, is the home of
the honey-bee, and of the silk-worm, almost the only insects directly
useful to man.
