A form of engine belong-ing to this class, with which the writer happens to befamiliar, is that known in the market as The StraightLine Engine. This engine, so far as it is novel, is the inventionof, and also is designed by. Professor John E. Sweet, form-erly the superintendent of the workshops in which instruc-tion in machine work was given in the Department ofMechanical Engineering of Cornell University—a positionin which he became widely known as one of the most skilfuland ingenious mechanical engineers in the United States—later a President of the American Society of MechanicalEngineers. The first of these engines was built at SibleyCoiiege, Cornell University, in 1871, under the instructionof the designer. A second, built in 1875, i^ still in use.

The problem, proposedto himself by the inventor, was to design an engine which,while consisting of the smallest possible number of parts,should, nevertheless, be economical in its use of steam,capable of the most perfect regulation attainable with anyknown device, strong and stiff in every part subjected to theworking strains of an engine working at high speed, inex-pensive in first cost, and durable as a simple engine can engine is shown in the accompanying illustration,A vertical engine, which is shown at the end of thearticle, is also designed for all powers ; there seems noreason why it should not prove a good style for heavy work;better in some respects, in fact, than the horizontal engi
