Mr. Louis Entzminger I regard as the greatest Sunday School man on the American Continent. I have reached this opinion after close observation of his work in other fields, and after two extended engagements of Mr. Entzminger in my own church and Sunday School. His present undertaking in the form of Bible exposition adapted to Sunday School workers, is at once an important and much needed work. Having examined his production upon Genesis, I hereby express the hope that he may give equal thought, time, and intelligent treatment to the entire Bible. In case he accomplishes that task, he will put over a colossal undertaking, and one that will bring him the gratitude of thousands of Sunday School teachers and scholars. It has long been my opinion that his exceptional talents should be devoted entirely to the important work of Sunday School teaching, organization, and administration. W. B. RILEY.
