MECHANICAL DRAwING-In San Fran
cisco much good has been accomplished
toward educating our young men in the
principles of mechanical drawing through
the classes started under this auspices of the
Mechanics Institute and also that at the
Cogswell School. Many students however,
are unable to avail themselves of these ad-
vantsges. To such persons this work, pre-
pared by Professor Charles William Mac
Cord, will be found OF great value. Those
who have the benefit OF an Instructor may
also profit largely by its aid. The plan laid
down by the professor for the instruction of
the students eomprehends, after reasonable
skill in execution has been acquired the
delineatlon of solid objects. In the treat
ment of projection the aim is to lead
way as they would appear from differ
ent points of view; the express de-
sign being to keep out of sight so
far as possible the artificial and often use
less stage machinery OF descriptive geom-
etry. This certainly seems very sensible
and practical plan, and the author says that
successful course Of instruction during
twenty years has proved its success. The
contents include chapters on straight lines
anu circular, exercises IN the drawing of
nOn-cireular curves. the principles of pro-
| lection, objects in inclined positions, appli-
cation of the helix IN the drawing of screws,
construction of the screw propeller, etc.
second part of the work is devoted to "Prac-
tical Hints to Draughtsmen.' In this por-
ton working drawings are defined and rules
OF projection given. A chapter On free
hand sketcblng Is full of valuable sugges-
tions and instructive directions to the stu.
dent The value of the ability to sketch
free-hand is obvious; to the designer the
importance cannot be overestimated. lot
OF practical suggestions and examples are
to be found included in this subdivision of
the work; Another chapter is given up to
drawing Instruments and materials. Draw
ing and design serve TO enlighten the text
and aid the student. The work is hand
somely and strongly bound. New York:

STANDARD ELECTRICAL DICTIONARY
This is book which fully supplies the
popular demand for concise encyclo-
peda of electrical science. Its six hundred
and odd pages contain vast amount of in
formation, much of which cannot con-
veniently be found elsewhere. The com-
pler Is L. OCoEor Sloane. author of several
works ON electricity, who com bines with a
clear knowledge of the subject the ability
to define in few words terms which it is
essential that every practical electrician
should understand. There is perhaps no
other single volume on the subject which
contains so much 0f value to the student
anxious to keep abreast of the times. This
is the electric aye, yet to the general reader
volts, amperes and ohms are words in an
unknown tongue, conveying no definite
ideas. 1t Is a genuine satisfaction to find
them made so plain that they no longer
seem symbols of mystery. MIR. Sloane's
dictionary is well illustrated and can be
recommended to all who desire to keep
posted regarding the recent marvellous
progress in all that pertains to electricity
and electrical devices. Published by Nor

stories by Richard Malcolm Johnson The
volume includes ''Mr. Fortner's Claims"
''Oid Gus Lawson" San Adventure Of Mr..
Joel Bozzle," "A Moccasin Among the
Hobbys" and "a Surprise to Mr. Thomp-
son Byers." Several of these have been
heretofore printed In magazines, but "Old
Gus Lawson" is now published for the first
time. 1t is unnecessary to say anything in
commendation of Mr.. JohnSon's short
stories; few American writers have more
admirers. The book is bound in the dainty
style which has served to commend APPLE
tons Summer Series to the reading public.
