et of specifications is really a work of art, and it is the aim ofthe publishers of this little volume to put in the hands of thosewho are only moderately schooled in the art of mechanical drawingthe means of developing themselves in the broader art of machinedrawing. The subject has been developed very logically, startingfirst with the presentation of the details and the conventionalWays of representing the parts of simple machines, followed bystandard methods of working out such mechanisms as screws,pulleys, cams, gears, etc. Finally, complete detailed drawingsare furnished and exhaustively discussed in connection with thedesigns of a duplex pump and of a direct-current generator.The presentation is exceedingly practical and will appeal to menwho are interested in either the mechanical or electrical fields.The plates are complete in themselves, but if a person wishes toobtain the maximum benefit from his study he may work outenlarged drawings to scale without any additional details.

MACHINE DRAWING PART I WORKING DRAWINGS METHODS AND CONVENTIONS In Mechanical Drawing, Parts I, II, and III, the commondrafting instruments and materials are described, and hints givenregarding their use; the fundamental geometrical problems are solved;the principles of orthographic projection are stated, and their appli-cation to intersections and developments illustrated. A carefulstudy of these Parts, with the actual drawing work incident thereto,should have given the student considerable facility in producinggood line work; he should now be able to draw neatly and accuratelyany simple piece which may be given him, correctly applying theprinciples as described. In producing working drawings the principles already laiddown are constantly used, and the more they are at the finger endsof the student the easier his work will become. The principles ofprojection must be thoroughly understood and fixed in the studentsmind in order that he may devote himself with the greatest applica-tion
