Excerpt from Furnace Draft: Its Production
In presenting this monograph to the public, I make no claim for its completeness, nor of my infallibility, but take pleasure in giving the reader some facts concerning mechanical draft in a handy form for ready reference.
Some of the material has already appeared in an article which I prepared for the Engineering Magazine.
Credit for the work of others is given as far as possible.
I trust that the book may be read as being unbiased, as far as any particular make of apparatus is concerned.
The rapid sale of the first edition of this book has led to its reissue as one of the Van Nostrand's Science Series, with a few corrections and additional matter added.
