Being a Description of the Square and Its Uses in Obtaining the Lengths and Bevels of all kinds of Rafters, Hips, Groins, Braces, Brackets, Purlins, Collar-Beams, and Jack-Rafters. - Also, us Application in Obtaining the Bevels and Cuts for Hoppers, Spring Moldings, Octagons, Stairs, Diminished Stiles, etc. - By Fred. T. Hodgson, author of "Practical Carpentry," "The Builders'Guide," etc. - Third Edition, Revised and Greatly Enlarged. - Illustrated by Nearly One Hundred Fine Engravings. - Cloth, gilt. . . $1

This is the only practical work on the steel square and its uses ever published. It is thorough, accurate, clear, and easily understood. Confounding terms and scientific phrases have been religiously avoided where possible; and everything in the book has been made so plain that a boy of twelve years of age, possessing ordinary intelligence, can understand it from end to end.

This new edition, just issued, is illustrated by nearly one hundred handsome engravings, showing how the square may be used for solving nearly every problem in the whole art of carpentry. The carpenter who possesses this book need not waste time and material " cutting and trying." He can lay out his work to a hair's breadth, and "cut to the line." And, in these days, the workman who can not lay out his work accurately at the first attempt stands no show.

The book is absolutely indispensable to every person who may have to use a carpenter's square. Joiners, cabinet-makers, bricklayers, stonecutters, plasterers, lumber-dealers, amateurs, and all who build a fence, tinker a gate, or make a chicken-coop will find something in this little volume that will help and aid them to do their work better and more intelligently than they could without a knowledge of its contents.

Many difficult and troublesome mathematical problems can be solved by the use of this tool, and the methods of solving them are shown in this book. It describes how painting, plastering, and brickwork can be measured, and how many mechanical difficulties can be overcome with great ease. It explains how ellipses, parabolas, octagons, circles, and many other figures, may be described by the steel square.

It is safe to say that this dollar book will easily enable any intelligent mechanic to save ten dollars in time and material during the first three months that he has it in use.

Being a Description of the Various Steel Squares and Their Uses in Solving a large number of Mechanical Problems in Constructive Carpentry, Joinery, Sheet-metal Work, Cut-stone or Brick-work. Also, showing how many Geometrical and other Problems may be solved by the use of the Steel Square. - By Fred. T. Hodgson, author of "The Steel Square and Its Uses," "The Slide-Bale, and Its Uses," "Practical Carpentry," "The Builders'Guide," &c-Finely Illustrated. - Cloth..............$1

This forms Part II of " The Steel Square and Its Uses," and is not in any sense a substitute for the First Part,which still remains what it always has been-a necessity to every intelligent workman. Part II is an extension and enlargement of the First Part, giving new problems, new methods, and new wrinkles for shortening the labor and increasing the accuracy of the workman. It is illustrated in the same handsome manner which characterizes the First Part, to which it forms a companion volume.

With these two volumes in his possession the workman has at command the entire practical mathematics of construction, and is prepared to lay out any piece of work more easily, quickly, and accurately than it can be done by any other method.
