a Falls was in existence the country round about was under
the sea; before that under glaciers; before that under the tropics, and
I don't know how many times it has swung on its pendulum between Frigid,
Temperate and Tropic Zones.

So you see we are getting lost in a labyrinth of mystery when we take
these known facts concerning the earth's age and try to definitely set
any particular number of millions of years as the old world's age.

CLOSING NOTE

A Little Appreciation to Everyone Who Reads This Book

And now my pleasant occupation of writing this book draws to an end. I
sincerely hope you have received some definite suggestions that will be
helpful to you; that's my first purpose.

I have more books in my brain in embryo. They are hatching out and you
may look for books of mine to appear every once in awhile so long as
ability to write is mine.

There is an indescribable something in my relation with my readers that
is sweet beyond words to tell. I look upon you, the readers, as brothers
and sisters; yes, more than that, you are my friends.

As I travel both in this country and abroad I drop in book stores and
meet the friends who sell my books and from them I hear some mighty
pleasant and enthusiastic expressions of approval. Appreciation is worth
more than dollars.

The daily increasing sales of my books is due to one thing, and that is
that you, my readers, my friends, are telling your friends to buy my
books. This personal interest and recommendation is advertising of the
most valuable kind.

Because you get your friends to buy, the sales are good and that's
encouragement. It's the spur that keeps me ever writing, planning, and
studying, that I may write more books.

So here is my hand of friendship, my heart's gratitude, my complete
appreciation of your interest and patronage.

We've spent many pleasant moments together in these evening round-ups,
and until we meet again in person or through one of my books, keep good
thoughts working for your benefit. Get serenity, poise, power, purpose
and good cheer.

You can be strong; you will be strong so long as you control your
thought habits.

Life is beautiful, it's well worth while. Clouds will come, obstacles
will confront you, troubles will get in your way; but each and all of
these will disappear, if you keep on your way, with courage, smiles,
will power, and perseverance.

And from me and my loved ones to you and your loved ones here ar
