UNITED STATES STANDARD SCREW THREAD GAUGE.

Some Things Personal.

In the preparation of this work the idea of self-help has never been forgotten; nothing has been held back or omitted which would, in the author’s opinion, tend to advance the student in the draughtsman’s art.

The volume contains the experience in practical drawing, as related to engineering and mechanics, of over one hundred years, i. e., the author’s, Mr. Perrott’s and Mr. Lucas’ experiences added together exceed that period.

Hence, the work should be really helpful; it has been aimed also to be entertaining and with easy tasks; all the illustrations of the book are recommended as models for practice--they have been selected with that view.

Moreover, as between author and publishers, the latter have agreed to issue the work in the most thorough style possible--as to paper, printing and binding--and to sell it at a very generously low price, considering all things.

With the closing words “hail and farewell,” the author bids adieu (God be with you) to the reader and the student.
