with the floating chances of the spawn!

Then the rich, sure food of mother-milk, the absolute adaptation, the
whole great living creature an alembic to gather from without, and
distil to sweet perfection, what the child needs. Contrast this with
the chances of new-born fish or fly, or even those of the bird baby,
whose mother must search wide for the food she brings. The mammal has

Then comes the highest stage of all, where the psychic gain of the race
is transmitted to the child as well as the physical. This last and
noblest step in the life process we call education. education is
differentiated motherhood. It is social motherhood. It is the
application to the replenishment and development of the race of the same
great force of ever-growing life which made the mother's milk.

Here are the three governing laws of life: To Be; To Re-Be; To Be
Better. The life force demands Existence. And we strain every nerve to
keep ourselves alive. The life force demands Reproduction. And our
physical machinery is shifted and rearranged repeatedly, with arrayed
impulses to suit--to keep the race alive. Then, most imperative of all,

thing--permanently; not merely more of this thing--continuously; but
better things, ever better and better types, has been the demand of life
upon us, and we have fulfilled it.

Under this last and highest law, as the main factor in securing to the
race its due improvement, comes that supreme officer of the life
