"As the treatise now stands, it is a most complete and practical guide in the spinning of cotton. It gives the dimensions and speed of machinery, draught and twist calculations; together with rules and examples for making changes in the size and number of roving yarn. The work will be found of value, equally by operatives and mill-owners. It is issued in a very neat style."—Arthur's Home Gazette.
"'The American Cotton Spinner and Managers' and Carders' Guide,' a practical treatise on cotton-spinning, giving the dimensions and speed of machinery, draught and twist calculations, &c., with notices of recent improvements, together with rules and examples for making changes in the size of roving and yarn. This work is compiled from papers of the late Robert H. Baird, well known as an expert cotton-spinner, and will prove of great service to cotton-growers, mill-owners, and cotton-spinners. This book will undoubtedly meet with an extensive sale in the South, where attention is beginning to be turned in earnest to manufacturing as well as growing cotton."—Drawing-room Journal.
"This is one of the most interesting and valuable of the many excellent little treatises on mechanical and manufacturing pursuits which have been published by Mr. Hart. The construction and working of a cotton-factory are thoroughly explained. Buildings, main gearing, water-wheels, picking and spreading machines, cards and carding, drawing-frames, speeders, throstles and mule spinning, are elaborately discussed, and to those engaged in the production of cotton goods, the volume must be exceedingly useful. To political economists and others, who feel an interest in the great progress of our country, the historical and statistical portions of the book will also be of value.
"'In 1770, there were exported to Liverpool from New York three bags of cotton wool; from Virginia and Maryland, four bags; and from North Carolina, three barrels. Last year England paid $71,984,616 to the United States for raw cotton, which sum is exclusive of that paid to other cotton-growing nations. In 1790 the first cotton-mill was erected in Pawtucket, Rhode Island. In 1850 the number of spindles in operation was computed at 2,500,000.' These facts are among the most signal evidences of the unexampled progress and prosperity of the country, and cannot be considered without emotions of pride and gratification."—N. Y. Commercial Advertiser.
"It is compiled from the papers of the late Robert H. Baird, well known as an expert cotton-spinner, and forms a practical treatise relative to spinning in all its departments and relations, the dimensions and speed of machinery, draught and twist calculations, &c. &c., which cannot but commend itself to the favourable attention of all connected with this important manufacturing interest."—North American.
