Man, at first an eager hunter of game, collected flocks and became a shepherd in order to profit by his possessions in time of dearth.

Further progress inspired him to till the earth and sow; a method which assured him of a certain living.

Evolution from the defective to the mediocre, and from the mediocre to the abundant, has led to the resources of agriculture.
The lower animals have preceded us on the way of progress.

The ancestors of the Philanthus, in the remote ages of the lacustrian tertiary formations, lived by capturing prey in both phases--both as larvae and as adults; they hunted for their own benefit as well as for the family.
They did not confine themselves to emptying the stomach of the bee, as do their descendants to-day; they devoured the victim entire.

From beginning to end they remained carnivorous.
