"This volume is prepared on the same plan as that on Cotton Spinning, and has a number of wood-engravings. It must prove invaluable to the iron master. It is certainly a book that has long been needed, and we know that it will be extensively circulated."—Germantown Telegraph.

Hart, is a treatise on moulding and founding in green sand, dry sand, loam, and cement, the moulding of machine-frames, mill-gear, hollow-ware, ornaments, trinkets, bells, and statues, with receipts for alloys, varnishes, colours, &c., by Frederick Overman, mining engineer. The work is illustrated with forty-two wood-cuts, and it gives plain and practical descriptions of these most useful arts."—Public Ledger.

"There is a great deal of well-digested information in this volume, exhibiting the most important discoveries in the Sciences and Arts, during the past year. In looking over it, one is surprised at the progress making in these branches, and in order to keep up with the age, such a book as this is absolutely necessary."—Evening Bulletin.
"Such a volume commends itself sufficiently to public favour by its title. The importance of possessing it is apparent at a glance, since the knowledge of a single one of these facts, or new discoveries in science and the useful arts, may very possibly be worth in cash to the buyer ten times the price of the book."—Scott's Weekly.
"The 'Year-Book of Facts' is another of Mr. Hart's excellent publications. It is a reprint from the London edition, and exhibits the most important discoveries and improvements of the year 1851, in arts, sciences, and mechanics. It is just the volume to have handy to take up when a few spare moments present themselves, which might otherwise be unimproved."—Boston Evening Gazette.
