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.
