, and covering the "Teen Age," has been
sadly neglected--the joint in the harness of our Sunday school fabric.
Here we have met with many a signal defeat, for the doors of our Sunday
schools have seemed to swing outward and the boys and girls have gone
from us, many of them never to return. We have busied ourselves to such
an extent in studying the problem of the boy and the girl that the real
problem--the problem of leadership--has been overlooked.

The Secondary Division is the challenge of the Sunday school and of the
Church today. It is during the "Teen Age" that more decisions are made
_for_ Christ and _against_ him than in any other period of life. It is
here that Sunday school workers have found their greatest difficulty in
meeting the issue, largely because they have not understood the material
with which they have to deal.

We are rejoiced, however, to know that the Secondary Division is now
coming to be better understood and recognized as the firing line of the
Sunday school.

What has been needed and is now being supplied is authoritative
literature concerning this critical period. Indeed, the Sunday school
literature for the Secondary Division is probably appearing more rapidly
now than that for any other division of the school.

This book is a choice contribution to that literature. It comes from a
man who has devoted his life to the boys and girls, and who is probably
the highest authority in our country in this Department. The largest
contribution he is making to the advancement of the whole Sunday school
work is in showing the fascination, as well as the possibilities, of the
Secondary Division. We are sure this little book will bring rich returns
to the Sunday schools, because of the large number who will be
influenced, through reading its pages, to devote their lives to the
bright boys and fair girls in whom is the hope, not only of the Church,
but of the World.
