In the Warm-Temperate Zone, though the Sun never reaches the zenith, yet
during the long summer his rays are almost vertical; while the winter is
so mild that snow and ice are of rare occurrence.
Here the vegetable world is less prodigal in species, and less luxuriant
in growth, than in the tropical regions; still, verdure is continuous
throughout the year, and fruits and flowers succeed each other almost
without interruption.
The animal world shows a similar, though less marked, decrease in the
exuberance of life. The higher orders are less numerous, the individuals
less gigantic and powerful; yet the antelopes, among the most graceful
of animals, and the camel, one of the most useful, especially
characterize this zone.
