Although this competition is nowhere more active, and the dangers to which each individual is exposed nowhere more numerous, yet nowhere is this enjoyment more vividly displayed. If vegetation had feeling, its vigorous and rapid growth, uninterrupted by the cold sleep of winter, would, one would think, be productive of pleasure to its individuals. In animals, the mutual competition may be greater, the predacious species more constantly on the alert, than in temperate climates; but there is at the same time no severe periodical struggle with inclement seasons. In sunny nooks, and at certain seasons, the trees and the air are gay with birds and insects, all in the full enjoyment of existence; the warmth, the sunlight, and the abundance of food producing their results in the animation and sportiveness of the beings congregated together.
