“DEAR SIR,
“You will please pardon the intrusion of this letter. I am a
Sunday School teacher, and have been a Christian for three
years.
“A month ago, as a result of reading the _Clarion_ and Haeckel,
I became disturbed in my mind, and wished to resign my class. I
sought the assistance of my minister. Instead of answering my
doubts himself he placed a copy of _When it was Dark_ in my
hand, telling me to read it prayerfully, and go to him again.
The following evening I completed the reading of a book whose
influence will live with me. My dear sir, I feel I cannot thank
you half enough, and I shall never cease to thank God that the
book was written.
“I saw my minister, not with any doubts this time, but with my
faith renewed, and with a fixed determination to work harder
for my Divine Master.
“I expect you will receive many letters expressing thanks, but
I cannot refrain from adding my humble testimony.
“Allow me to remain, sir,
“Yours very faithfully.”
