ter. of this city is the author has re-
Gently been issued from the press f.

(From Telephony
Trying to run a telephone business
without copy of Van Deventer's
"Telephonoloy" is as nearly impos-
sible as to wire up central office
protector frame without a soldering
copper. This book has become ex-
traord!narily popular throughout the
field. and the appearance of new
edition at such a comparatively early
date after its first appearance is a
practical testimonial to the success It
has met. This Is no doubt due to the
breadth Of the experience Of II. r.
Van Deventer. Of Sumter. s. c., the
author.
Although thoroughly trained
telephone engineer. who is entitled to
carry two university degrees after his
name, Mr.. Van Deventer has remark
able sympathy with the man who
begins his electrical education, as
we'll as his telephone career. with a
soldering copper or a digging bar in
his hands. and understanding Of what
he needs to improve his work, his
position and his salary. So the book
Is adapted as much to the needs of
the man who is beginning at the
ground to work up as IL Is indispen-
sable to one who has already advanc-
ed to the position OF wire chief. su-
perintendent or manager and realizes
that telephone work Is SO complicated
and covers so broad a field that he
must be seeking help for the solution
of new problems every day.
"A strong feature Of "Telephonol-
ogy" Is its treatment of the practical
problems of the small exchange,
showing how to test equipment and
materials so as to purchase wisely,
comparing in detail the structure and
performance Of various classes of
equipment, carefully describing home
made apparatus, useful experiments,
snort cuts and make-shifts, etc.
The author knows how to make
difficult subjects clear to the reader
by the use Of plain English, handling
even such subjects as the use of the
more expensive testing instrument
with surprising clearness and free
dom from the use of complicated
mathematical expressions.
The new edition is brought UP to
date by the addition of chapters on
Railway Telephony" and Re
cent Progress" including Major
Squier's system Of multiplex tele-
phony' the Automanual system, etc.
