There is nothing experimental or visionary about the book, all devices being in actual use
and giving good results. It might be called a compendium of shop methods, showing a
variety of special tools and appliances which will give new ideas to many mechanics, from
the superintendent down to the man at the bench. It will be found a valuable addition to
any machinist's librarjr, and should be consulted whenever a new or difficult job is to be
done, whether it is boring, milling, turning, or planing, as they are all treated in a practical
manner. Fifth edition. 320 pages. 250 illustrations. Price $^.50

THE WHOLE FIELD OF MECHANICAL MOVEMENTS
COVERED BT MR. HISCOX'S TWO BOOKS

We publish two hooks by Gardner D. Hiscox that wiU keep you from "inventirig" things thai have
been done before, and suggest ways of doing things thai you have not thought of before. Many a
man spends time and money pondering over ^ome mechanical problem, only to learn, after he
^ has solved the problem, that the same thirty ?uis been accomplished and put in practice by others
long before. Time and money spent in an effort to accomplish what has already been accomplished
are time and money LOST. The whole field of mechanics, every known mechanical movement,
and practically every device are covered by these two books. If the thing you ward has been invented,
it is illustrated in them. If it hasn't been invented, then you'll find in them the nearest things
to what you want, some movements or devices tJuU trill apply in your ccue, perhaps; or which
wiU give you a key from which to work. No book or set of books ever published is of more real
value to the Inventor^ Draftsman, or practical Mechanic than the two volumes described below.
