thly or heavenly reason why a
minister should not have a blackboard or an easel on the pulpit
platform or in the prayer meeting room to help him keep his audiences
awake while he tries to drive truth home to heart and mind. It is
every preacher's duty to be _interesting_, and if this book and
the blackboard, or the equipment for chalk talk work, will help him to
be so, then it is his plain duty to buy the book and secure the chalk
and easel and _"get busy" being interesting_!

And there is one more thing: Don't forget you can do it--_if you
try_!

And now, with these general instructions and observations, the book is
commended to the use of all who have the love of Christ in their
hearts and who, as faithful workers, may wish to add one more working
tool to those they have used so well.

THE TWO FACES
--Our Thoughts.
--Optimism.

"As a Man Thinketh in His Heart, So Is He"--A Lesson in Character
Building.

THE LESSON--That our thoughts determine the kind of life we live,
and often proclaim character in the face.

If the teacher succeeds in impressing upon the pupil the great need to
"guard well thy thoughts," for "our thoughts are heard in heaven," he
will have accomplished a work of immeasurable good in the life of the
child or youth who is the fortunate object of such interest.

~~The Talk.~~

"Let us think a while about our thoughts. Do you know it is a fact
that a man, seated quietly in an easy chair on his front porch on a
summer evening, may be sinning against God and man? Yes, it's true,
for, as he sits there in the silence, he can hate another man with a
bitter hatred; he can plan to rob him or burn his house or slander him
or even take his life. And the worst of it all is that if he allows
such thoughts to rent a room in his head it may not be long before his
evil designs have become awful deeds.

"Not many boys or girls think such terrible things, but thoughts of
this kind are only the little bad thoughts allowed to grow year after
year in the head and in the heart. And do you know, also, that if you
allow these little bad thoughts to live in your head and heart for a
while, they get so bold and 'sassy' that they insist on taking
possession of the best room of your head and the parlor of your heart
and defy you to put them out? The only thing to do is to throw them
out the very first time they come in.
