Preface The Author takes great pleasure in acknowledging the eminent services rendered him in the literary and scientific portions of this work, by E. N. Jencks, A. M., Professor of Mathematics and Natural Sciences; and the Public cannot fail to appreciate the value of his labors in these departments. The inception of the work, its original designs, and the entire system, are mine. Whatever is found in it purely literary and scientific, I cheerfully attribute to his assistance. And believing that the work will supply a pressing want, and will be useful both to those who are devoted to the Mechanic Arts and to Amateurs who have felt the necessity of a faithful guide in house-building and other structures, especially in new settlements, I can confidently commend it to them as supplying this deficiency.
