n the womb will be called upon to nourish and support a
child. If it did not get rid of the old blood, it would not be in a
healthy condition to nourish and take care of a baby, nor would its
interior be ready to supply new fresh blood for the growth of the
infant. Hence nature constructs and builds a new "nest" in the interior
of the womb each month. It very much resembles the new home into which
the bride and groom, go to begin housekeeping.

When you told your little girl the story of life, you particularly drew
her attention to the important fact that every living thing is created
by the union of a male and female principle, and, therefore, has a mamma
and papa. This applies to trees, flowers, vegetables, fish, animals,
birds, insects,--every living thing, including human beings. We have
seen that the ovule from the ovary is the female egg, or principle. It
is the part the female contributes toward the future child. Before a
child is possible, however, the ovule must meet the egg from the male.

THE MALE OR PAPA EGG.--The male or papa egg is called a "spermatozoa."
It reaches the interior of the womb through the lower opening, which you
will remember opens into the vagina. Emphasize to your daughter that the
female ovule or egg, and the male egg, or spermatozoa, are minute
objects, so microscopically small that a hundred million of them could
comfortably lie upon a ten-cent piece.

THE FUNCTION OF THE SPERMATOZOA.--God gave the male spermatozoa the
power to move. To watch them under the microscope you would imagine you
were looking into a bowl of water, in which there were hundreds of
little fish all squirming around. But the most wonderful thing about
them is, they can only move in an upward direction,--they seemingly
cannot move downward, or sideways. If you think for a moment you will
understand why God gave them this marvelous property. When the male
semen is deposited in the female vagina, there are thousands of these
minute, living, moving spermatozoa in it. The womb is above the vagina,
and the female egg is in the womb, consequently, to reach this egg, the
spermatozoa must travel upward. To travel in any other direction would
be fruitless energy. There is only one female egg, but there are
thousands of male eggs, or spermatozoa; it is easy, therefore, to
comprehend how one of these spermatozoa should exactly be in line with
the female egg in its upward path, since there are so many of them. It
is only nece
