of his brother mechanics willing, and often eager, to give him the informa tion which he requests. I should question if another instance could be found of men so ready to possess their goods in' common, losing sight of all emolument and fame, and influenced by the pure motive of benefiting those who are but too often considered and treated as rivals in trade."Extract from the Letter of a Correspondent, p. 396, Vol. IV. "No garden library ought to be without this Periodical, which contains a body of useful practical information on almost every subject. There is no doubt much in it respecting Steam Engines, and other machines, of little interest to the gardener, but there are also Treatises on Grammar, Arithmetic, Geometry, Perspective, and innumerable Articles on Domestic and General Economy, applicable to every-day life."-Loudon's Remarks on the Benefits of Garden Libraries.
