~STEEL~

=Steel: Its Selection, Annealing, Hardening, and Tempering.= By E. R. MARKHAM.

This work was formerly known as "The American Steel Worker," but
on the publication of the new, revised edition, the publishers
deemed it advisable to change its title to a more suitable one.
It is the standard work on Hardening, Tempering, and Annealing
Steel of all kinds. This book tells how to select, and how to
work, temper, harden, and anneal steel for everything on earth.
It doesn't tell how to temper one class of tools and then leave
the treatment of another kind of tool to your imagination and
judgment, but it gives careful instructions for every detail of
every tool, whether it be a tap, a reamer or just a
screw-driver. It tells about the tempering of small watch
springs, the hardening of cutlery, and the annealing of dies. In
fact, there isn't a thing that a steel worker would want to know
that isn't included. It is the standard book on selecting,
hardening and tempering all grades of steel. Among the chapter
headings might be mentioned the following subjects:
Introduction; the workman; steel; methods of heating; heating
tool steel; forging; annealing; hardening baths; baths for
hardening; hardening steel; drawing the temper after hardening;
examples of hardening; pack hardening; case hardening; spring
tempering; making tools of machine steel; special steels; steel
for various tools; causes of trouble; high-speed steels, etc.

processes for the heating, annealing, forging, welding,
hardening and tempering of steel, making it a book of great
practical value to the metal-working mechanic in general, with
special directions for the successful hardening and tempering of
all steel tools used in the arts, including milling cutters,
taps, thread dies, reamers, both solid and shell, hollow mills,
punches and dies, and all kinds of sheet-metal working tools,
shear blades, saws, fine cutlery, and metal-cutting tools of all
description, as well as for all implements of steel both large
and small. In this work the simplest and most satisfactory
hardening and tempering processes are given.

The uses to which the leading brands of steel may be adapted are
concisely presented, and their treatment for working under
different conditions explained, also the special methods for the
hardening and tempering of special brands.

A chapter devoted to the different processes for case-hardening
is also included, and special reference made to the adaptation
of machinery steel for tools of various kinds, Fourth edition.

~TURBINES~

=Marine Steam Turbines.= By DR. G. BAUER and O. LASCHE. Assisted by E. LUDWIG and H. VOGEL.

Translated from the German and edited by M. G. S. Swallow. The
book is essentially practical and discusses turbines in which
the full expansion of steam passes through a number of separate
turbines arranged for driving two or more shafts, as in the
Parsons system, and turbines in which the complete expansion of
steam from inlet to exhaust pressure occurs in a turbine on one
shaft, as in the case of the Curtis machines. It will enable a
designer to carry out all the ordinary calculation necessary for
the construction of steam turbines, hence it fills a want which
is hardly met by larger and more theoretical works. Numerous
tables, curves and diagrams will be found, which explain with
remarkable lucidity the reason why turbine blades are designed
as they are, the course which steam takes through turbines of
various types, the thermodynamics of steam turbine calculation,
the influence of vacuum on steam consumption of steam turbines,
etc. In a word, the very information which a designer and
builder of steam turbines most requires. Large octavo, 214
pages. Fully illustrated and containing eighteen tables,
including an entropy chart. Price, net =$3.50=

~WATCH MAKING~

=Watchmaker's Handbook.= By CLAUDIUS SAUNIER.

No work issued can compare with this book for clearness and
completeness. It contains 498 pages and is intended as a
workshop companion for those engaged in watch-making and allied
mechanical arts. Nearly 250 engravings and fourteen plates are
included. This is the standard work on watch-making. Price

how to construct necessary shop equipment. Proceeds then to the
actual welding of all automobile parts, in a manner
understandable by every one. _Gives principles never to be
forgotten._ Aluminum, cast iron, steel, copper, brass, bronze,
and malleable iron are fully treated, as well as a clear
explanation of the proper manner to burn the carbon out of the
combustion head. This book is of utmost value, since the
perplexing problems arising when metal is heated to a melting
point are fully explained and the proper methods to overcome
them shown. 167 pages, fully illustrated. Price =$1.00=

=Everyday Engineering=

A monthly magazine devoted to practical mechanics for everyday men. Its aim is to popularize engineering as a science, teaching the elements of applied mechanics and electricity in a straightforward and understandable manner. The magazine maintains its own experimental laboratory where the devices described in articles submitted to the Editor are first tried out and tested before they are published. This important innovation places the standard of the published material very high, and it insures accuracy and dependability.

The magazine is the only one in this country that specializes in practical model building. Articles in past issues have given comprehensive designs for many model boats, including submarines and chasers, model steam and gasoline engines, electric motors and generators, etc., etc. This feature is a permanent one in this magazine.

Another popular department is that devoted to automobiles and airplanes. Care, maintenance, and operation receive full and authoritative treatment. Every article is written from the practical, everyday man, standpoint rather than from that of the professional.

The magazine entertains while it instructs. It is a journal of practical, dependable information given in such a style that it may be readily assimilated and applied by the man with little or no technical training. The aim is to place before the man who leans toward practical mechanics, a series of concise, crisp, readable talks on what is going on and _how it is done_. These articles are profusely illustrated with clear, snappy photographs, specially posed to illustrate the subject in the magazine's own studio by its own staff of technically-trained illustrators and editors.

=The subscription price of the magazine is one dollar per year of twelve numbers. Sample copy sent on receipt of ten cents.=
