while the pine, walnut, and chestnut may be found at or near the extreme
southern limits.

In all of these three grand divisions of climate, however, exceptional
localities exist where there is a marked nonconformity to the prevailing
characteristics. The peninsula of Florida is such an exception, owing to
its peculiar location, and the great humidity of its atmosphere during a
considerable fraction of the year. Here we have a fully developed season
of periodical rains, beginning usually in June and ending in the latter
part of September. The winter is the dry season, being contrary to the
general rule applying to tropical and sub-tropical areas, and forms,
