OPINIONS OF THE WORK:

[From the Telegraph.]

This is a book which every carpenter and house builder should own.

Mr. Livermore:

Dear Sir,—I have deemed the "Carpenter's Assistant and Rural Architect," by Messrs. Brown and Joy, published by you, as one of the most valuable guides and books of reference in my library, and take an early opportunity to congratulate you on the appearance of a new and improved edition of the work, which I have just purchased.

The Lithographic Plates, comprising designs for church edifices, adds in my opinion a striking feature to the book, and I have no hesitation in averring that it will be sought for by every Architect, Builder, and Carpenter in our country, who wishes to possess the most concise and practical treatise published.

Respectfully yours,
SAMUEL PHILLIPS, Architect and Builder, Boston.

From Practical Carpenters and Architects.

We, the undersigned citizens of Worcester, Mass., practical carpenters, are personally acquainted with William Brown, Esq., Architect, and author of a work, entitled the "Carpenter's Assistant and Rural Architect." We have examined that work with attention, and commend it to all who are interested in the study or practice of the art, as a valuable treatise on architecture, and it is eminently practical in its character. We cheerfully recommend it to the patronage of carpenters and the public.
