A simple sliderule setting takes the place of Mr. Maillouxs Chart ofReciprocals, and the General Speed Tractive EffortCurve is also new. In regard to this last, the writer hasfound it so useful that he has plotted these curves for all themodern railway motors, thus enabling definite comparisonsto be made for an equipment having a certain frictioncurve. Other methods of plotting these curves are used. L. (Electrical World and Engineer, , pp. 96-97 and 219-221) has shown an important de-velopment with regard to Mr. Maillouxs method whichtends toward a solution by an algebraic method of mostspeed time curve problems. H. S. Knowlton has also useda method of speed distance curves for the analysis of con-ditions on the Boston Elevated
