Conducted by "an association of practical mechanics, " this magazine proposed to "diffuse general elementary knowledge, " to discuss questions and queries sent by readers, and to publicize new inventions. It published about one page each of questions and answers; listings of new publications and American patents; short notes on inventions; and articles, with illustrations and diagrams, on scientific subjects-steam engines, the elements, minerals, and metals. Some non-scientific material appeared also. Cf. American periodicals, 1741-1900.
