serial stories of thousands of plants and animals. In the case of man,
not only do we find that there were once human beings on earth like
the caveman with low forehead and huge jaw, but nothing has ever been
found to indicate that there were any higher types of human beings in
existence in his day. And both the caveman and the handsomest human
beings of to-day--the captain of our football team, for example--have
essentially the same bodily framework as the monkey tribe. This does
not mean that man--even so low a creature as the caveman--descended
from monkeys, any more than the fact that he has a backbone means he
descended from humming-birds. But the backbones in humming-birds,
monkeys, and men show that all are descended from older types of
backboned creatures. As monkeys and men are much more alike than men
and birds they are evidently more closely related.
We might suppose, to be sure, that men and all other forms of life
which they resemble in any way were so made from the beginning; that
is, if we hadn't learned from the records of the rocks that they
_weren't_ so made from the beginning. Yet, even after that, we might go
on supposing that each species was created separately, but that the
form was changed from age to age. But in that case what are you going
to say to this:
In man's body are several organs that are useless and often harmful.
Other animals, also, contain among useful organs some that are
"out-of-date," as we would say if we were speaking of some old machines
in a machine-shop. Why, in making a brand-new species, shouldn't Nature
have all the latest improvements from the start, just as man does in
building a brand-new home? If each species was separately created it is
hard to understand why these useless or harmful organs should be kept;
but if one species grew out of another, by gradual improvement, just as
cities grow out of villages, this is exactly what we might expect.
One of these useless organs in man is called the "vermiform appendix."
It is always getting its name in the papers by giving trouble to some
prominent man. Now this appendix, while a perfect nuisance to human
beings, is just the thing for cows and other grass-eating animals. In
them it is very large and of great use in digestion, while in the case
of man and the monkey family it has shrunk into a little affair that
puts in all its time either doing nothing or getting out of fix.
III. Upward; Always Upward
These are some of the reasons why the various varieties of animals are
supposed to have descended from common ancestors and to have undergone
endless changes of form; changes as strange as anything that was ever
written into a fairy story or acted out in a Christmas pantomime. There
are other things quite as convincing and even more thrilling to read
about, such as the little theatre in the chicken's egg where strange,
changing shadows re-enact the drama of ancient life; but these I am
here passing by because my pages are running out and I want the rest
of them to speak of what seems to me to be the greatest lesson of this
whole book; the greatest and most useful and happiest lesson Science
or any kind of book can teach; namely, that not only is the universe
governed by Laws and Mind, but that all these laws act together as one
Great Law and are working out one general result, the constant advance
of all things toward a higher life.
HOW MAN HAS RISEN AS HE DESCENDED
As there was a period in human history when there were no human beings
on earth higher than the cave-dweller, so there was a time when the
highest forms of animal and vegetable life were minute creatures and
plants consisting only of a single cell. It is such low forms of
vegetable life that make the scum on the still waters of a pond. Step
by step, in both the animal and vegetable world, rose the higher forms.
The descent of man from lower forms of life used to be considered
by many people as a thought that degraded humanity, but it is the
most promising fact in all nature. The striking thing is, not that
we are related in some way to the apes and the cavemen but that such
a creature as an ape or a caveman should have helped develop such a
beautiful thing as a little child.
This progress has not been steadily upward. The world of life, like
the surface of the globe itself, has had its ups and downs. Wonderful
nations like Greece and Rome have risen and flourished and passed
away, but they left the best of themselves, the part that time cannot
destroy. The Greeks taught us literature and art and the grace of life.
The Romans gave us a science of government and a solid way of doing
practical things, such as the building of good roads and bridges. The
great lesson of history is that civilization and human liberty and all
the things that make life worth living have not only survived the fall
of empires but stand to-day on higher and firmer ground than they ever
did before.
THE WORLD THAT MOTHER MADE
But do you know who was at the bottom of it all? Mother! All the things
that men have done in the development of national life, with its arts
and industries, everything we call civilization, grew out of the life
and industry of the home, and it was mother who finally made the home.
The mother idea came into the world with the first seed that ever
started out to make its own way; for the mother plant had provided it
with food enough to keep it going until it could get well-established
in business. But the kind of mothers we know, mothers who stay with
their babies and feed them, came very late in the long story of life.
In the early days the world was not only without flowers and birds
and the beautiful trees and varied landscapes we know, but it was
motherless, in the sense that we understand mothers. In the lowest
forms of life, such as the insects, the mothers and children never
saw each other at all; for among the insects just as it is to-day the
mother simply laid the eggs and then, before the little insects were
born, passed away. Even among the fish, who are much closer relations
of ours than the insects--since fish belong to the great brotherhood
of the backbone--the sense of motherhood doesn't get beyond looking
after the eggs. So with the next higher group to which the frogs
belong; and the next, the reptiles. Only with the birds, the next group
above the reptiles, do we begin to see what motherhood means. Then at
the very top of the list come the class of animals whose very name has
"mamma" in it; the "mammalia." Among these, even outside the human
race, we find very striking examples of family love and devotion. The
gorillas, for instance, although they haven't what one would call an
attractive face, are good to their folks. Not only does Mamma Gorilla
nurse her babies and carry them in her arms much as a human mother
does, and fight and die for them, but a famous African traveller tells
of a Mamma Gorilla who stayed safe with the babies in their humble home
of sticks in the fork of a tree while Papa Gorilla sat all night at the
foot of it, with his back against the trunk, to protect them from a
leopard that had been seen prowling around.
Among most animals below man the babies are soon able to leave mother
and shift for themselves, but in the case of human beings the baby is
helpless for a much longer time. So, even among the lowest savages, it
was necessary for father and mother to keep together and look after
their children. Thus grew up family life; and out of the family the
tribe; and out of many tribes living together and closely related, grew
first small and then larger nations. Yet, always at the beginning, it
was the mother, more than the father, who looked after the children and
taught them, so bringing before the world the idea of doing things, not
for one's self alone but for others. From this came the mutual giving
and helping which made national life possible, and that is making this
a better and better world to live in.
IV. The Great Unseen
So it is very plain not only that the end, the purpose of all this
machinery and march of things that we have been going through since the
beginning of Chapter I, is to make life better, more beautiful both
in form and character, but to show that "all nature is on the side of
those who try to rise."[59] It is plain also that this end must have
been foreseen and intended from the beginning; for, from the very start
each change in the world and in life was a preparation for another
and a greater change. The change from rock to soil made plant life
possible; the growth of plants made animal life possible, and so on up
through the long succession of changes in this tree of life by which
all things are related and which gave us the infinite variety of good
things we already have--fruit, homes, churches, schools, art galleries,
books, railroads and steamships that make the whole world neighbors;
the telegraph, the newspapers, and the magazines that carry thought and
knowledge and plans for the common good so fast and far that already
it is as if a whole nation with its millions had a heart and brain in
common.
[Footnote 59: Drummond: "The Ascent of Man."]
Man himself, you see, has become one of the great forces of nature in
the evolution of nature, in the blossoming out and fruit-bearing of
things. But now notice this: Back of all that man does and all that the
rest of nature does is the great controlling force called Mind; and
this Mind is invisible. If I should say of some great man that he had a
powerful mind you would know just what I meant; but if anybody should
ask "What did his mind _look_ like?" you would think that was an odd
question, wouldn't you?

THE FIRST DAY OF CREATION
]
THE MYSTERIOUS PRINCESS HIDDEN IN THE BUD
So it is and has been from the beginning. We can see the _results_ of
changes of one thing into another but never just how the changing is
done. While it is no longer believed that species were given a certain
form in the beginning and that they have always kept that form, it
is still true that each species comes into being from some unseen
cause--"all of a sudden," as it were. Because species thus seem to vary
of themselves, and not for any reason that we can see these changes are
called "spontaneous variations." Always back of the material nature we
can see is a nature that is not material; a part of nature that, like
the mind of man, we can neither see nor hear nor feel nor know by any
of our five senses. Some Unseen Power forms the baby plant out of the
seed; some power changes the leaves hidden away in the bud into the
petals of the flower. When the leaves gather to form the bud, like
little hands playing "button, button, who's got the button," where do
you suppose the flower is? It _isn't_. It has not yet begun to be. But
soon, as if some magician had waved his wand and said "Presto! Change!"
the pink petals begin to form there in the dark of the cup and, first
thing we know, out steps Miss Blossom, all in her pink and gold like a
princess dressed for a ball!
But always hidden in a mystery these changes take place. We can peep
into the growing bud as often as we like and we will never catch the
fairies making the dress, nor the princess putting it on. We always see
the thing after it is done!
WONDERFUL ART BUT WHERE IS THE ARTIST?
Another thing: How do the fairies of Roseland remember every spring
just how a rose looked, when the roses of last year have been dead
and gone so long? You see they work without a model, something great
artists seldom do; and in some kinds of work, as busts and portraits
and landscapes, never do at all. Even the most powerful microscope
doesn't show any pattern in the seed for the seed to go by in growing
into the finished plant; or in an egg to tell it what kind of a bird it
is expected to be. No, not the trace of a pattern. What then, guides
the growth of the seed; of an oak, say, so that it finally and always
takes the family form? Some Power, evidently, as intelligent as the
power that moves the hand of the human artist when he paints that oak
into his landscape. How many of us have stopped to think that not only
in the world of mind but in the material world itself, all forms of
_power_ are as invisible as the fairies that work unseen in the rosebud
and the little birds' egg and the big rock? All power--what we call
steam power, wind power, electric power and the rest--are not only
unseen but unseeable, unfeelable, untastable. We know steam power only
when heat gets into the water and makes steam; electric power only when
it gets into a wire or a dynamo; or, passing by unseen ways through the
air, moves the wireless telegraph receiver; gravity power only when it
moves something as the water of a waterfall; or when it is helping to
hold things--the earth and the other worlds--in their appointed paths.
HIDE AND SEEK IN THE LIBRARY
You can easily see why evolution is the most talked about of
all phases of science--of the study of this wonderful world we
live in. One reason is it's such an astonishing thing in itself,
this relationship of all forms of life, trees, kittens, birds,
and everything; another reason is that in reading the books on
evolution you're taken into every field of knowledge and into the
most curious and striking aspect of things in those fields. Could
anything be stranger, for example, than a little theatre in a
chicken's egg, over which pass strange shadowy forms that seem to
retell, in a kind of moving picture show, the story of how one form
of life developed out of another?
Drummond's "Ascent of Man" tells about that and covers the whole
subject of evolution. It is one of the books which no one who has
heard of this wonderful story of life should fail to read. Doctor
Drummond's way of telling the story is very attractive. Readers
from the Eighth Grade up to the Eightieth will delight in it,
and they won't stop until they read it from cover to cover. I'll
guarantee that!
Then take such a book as "The World of Life," by Wallace. "Alice in
Wonderland" is nothing to it. Here are some of the things you will
find in it:
How there got to be different kinds of rabbits and what islands
have to do with it.
(Islands are almost as prominent in the story of evolution as they
are in the story of adventure. There are Robinson Crusoes until you
can't rest!)
How the pig in the struggle of life won out as usual.
Why the peacock has such a fine tail and how he overdid it.
How the elephant saved his life by lengthening his nose.
How the birds traded their teeth for feathers.
How shelled creatures coiled and uncoiled their shells.
Why we miss the "missing links." (As you go into this subject of
evolution you will hear a good deal about missing links.)
How they know butterfly wings are made first and the coloring and
patterns laid on afterward.
How much of a butterfly's beauty is probably known to the
butterflies themselves.
How Nature seems to make things just to be pretty.
And these are just a few of the things in _one_ of Doctor Wallace's
books.[60]
[Footnote 60: In addition to all this curious and absolutely reliable
information that ought to be interesting to every one is the fact that
Wallace shows in "The World of Life" how there must have been Mind and
Purpose back of it all. Doctor Wallace was a great traveller as well
as a great student of nature--one of the most famous in the history of
science. His works include: "Travels on the Amazon and the Rio Negro,"
"The Malay Archipelago," "Natural Selection," "Darwinism," "Island Life
and the Geographic Distribution of Animals."
There are so many books on this biggest of all nature
topics--Evolution--that they make quite a library in themselves. The
most famous of these books is Darwin's "Origin of Species," and it
is not at all hard to understand. Other books bearing directly or
indirectly on evolution are "Animals of the Past," by Lucas, "Creatures
of Other Days," by Hutchinson, Fiske's "Destiny of Man," and "Evolution
and Religion." A book for older readers--one of the latest and most
comprehensive treatments of the subject--is Osborn's "Origin and
Evolution of Life."]
Then he was such a fine man personally. Why, what do you think
he did? Although he thought out the principle of evolution
independently of Darwin, and wrote an essay on it before Darwin
had ever given his views to the world, yet after Darwin's "Origin
of Species"[61] came out Wallace gave Darwin all the credit,
and in his own autobiography always referred to the theory of
evolution as the "Darwinian Theory." Yet Wallace had a very good
reason for taking this generous attitude, as you will see from his
autobiography and other writings, and you are quite likely to find
the reason in articles on Darwin or Wallace or Evolution.
[Footnote 61: Of "The Origin of Species" it has been said that no work
ever produced so profound a change in the opinions of mankind.]
The relations of Darwin and Wallace furnish one of the finest
examples in history of the best thing in the world--human
friendship.
Of course, like so many other great men, Wallace was one of those
boys whose minds never grow old. Read in his autobiography how on
the day he first discovered a new species of butterfly it gave him
a violent headache, and he had to go to bed to get rid of it and
quiet his nerves--he was that worked up!
Darwin was much the same sort of a man. Everything in the world was
interesting to him. He wrote a whole book about "Fish Worms," for
example. And although probably the most famous man in the history
of natural science he was as humble as could be, always looking for
the truth and ready to accept criticisms no matter how much they
might upset his own previous conclusions, provided these opposing
views were supported by evidence. Of course you will want to know
more about his life, and you will find more in the "Life and
Letters of Charles Darwin," edited by his son.
How do you suppose this boy began being a great man--by collecting
beetles! Beetles and outdoor sport were his chief delight.
USE OF THE INDEX
SOME THINGS YOU CAN DO WITH THIS INDEX
I shouldn't be surprised if you thought that an index was the dullest
part of a book.
But it all depends! As a matter of fact, with your help, I am sure I
can make this index of ours one of the most interesting things in the
whole story; for, like the H. & S., it gives you a chance to "come into
the game." The mind enjoys books and grows upon them much as the body
grows on food, but, as in the case of both food and books--and books
are food--the good you get depends not only on the food but _how you
season it and eat it_. You can't expect _everything_ of the cook!
Everybody knows, of course, how to use an index to look things up once
in a while and it saves time if the index not only tells the page on
which a given subject is referred to, but conveys some idea of what
that reference is about, as this index tries to do. If, for example,
you are studying the Alpine regions in school you may already have
covered the question of how flowing water carves mountain valleys, but
you may not have had anything about why the Alps don't run north and
south, as so many of earth's great ranges do; and so what could be a
more interesting thing for you to take into those delightful class
discussions?
Your teacher knows, although you may not have realized it, that these
class talks and debates by the pupils themselves are _the big thing_
in modern teaching. The best education, we know nowadays, isn't the
mere cramming down of facts, as people used to think. _It's training in
thinking, and in standing on one's own feet!_
But memory training is important too; and an index is the best
thing in the world for that. Take some subject you're studying in
school--mountains, for example--they're always studying such big
things as mountains, the work of rivers, and so on; or if they aren't
to-day they will be tomorrow. Look at the references _as questions to
yourself_ and see how well you can answer them: "How do mountains help
make water-gates for the rivers?" and "Why do they have earthquakes in
regions where mountains haven't got done with their growing?"
Then you can have a lot of fun with these questions at home and with
boy friends, after you have read the book together. For instance: Just
how _did_ the pebbles help dig the Grand Canyon? And that's a poser
for many grown people too--people who've travelled and met the Grand
Canyon face to face! Try it on Father. Yes, and Teacher too. There are
none of her boys that a teacher is so proud of as the boys that have
initiative--_go-aheaditiveness_--and can _ask_ good questions as well
as answer them.
But, best of all, you can find no end of things to write about for
your language work in school and for the little books of your own that
I've already suggested in the H. & S. Take the subject of pebbles,
for example. Although this whole book has to do with the life and
adventures of pebbles, I haven't put the facts together in just the
way _you_ will if you follow out the references under the heading
"Pebbles" in this index. If you don't happen to remember how pebbles
act as bankers for the farmers, how they helped make the Great Lakes,
built the Grand Canyon, and so on, look these things up and then, as
they thus become digested in your mind, write about them in your own
way--the way you'd talk if you were telling somebody about it. Do that
and you'll _have_ something! one of those things that mothers show to
the neighbors, and that teachers show to visitors.
Of course you'll have to have a name for your story and you'll think of
plenty: "What One of My Pebbles Told Me," "The Pebbles in the World's
Work," "What a Wonderful Thing a Pebble Is!" "Why Common Pebbles are
Worth More than Diamonds"; for of course a diamond is a kind of pebble.
GETTING ACQUAINTED WITH YOURSELF
In all this you will not only find you'll have a good time, but,
let me tell you, you'll be getting the best part of your education;
you'll be getting acquainted with yourself, your undeveloped powers of
memory--reasoning--expression. You'll find before you get so very old
that one of the most important elements of success, of doing _your_
part in the world's great work of making itself better all the time, is
in _having something worth while to say and being able to say it_.
This was the making of the Greeks; and the Greeks, you know, were the
most wonderful people that ever were. It all started with old "Know
Thyself" Thales of Miletus.
That's what did it!

Transcriber Note
Minor typos corrected. Paragraph break inserted at the top of page
116 to accommodate placement of image related to the text therein. In
the original book, Mt. Fujiyama and Mount Rainier were on page 124 and
125 respectively with the caption spanning the two pages. The words "top"
and "bottom" were substituted for "left" and "right" respectively for their
orientation here. Also, the caption has been updated to say "FOUR THOUSAND".
