To secure easy lifting at high speeds the reactiondue to the thrust on (he movable portions, which is causedby the water, must be made as small as possible, unless thebalanced construction of the Pennsylvania design, as shownin our issue of November, 1896, is adopted. This is done inthe Lake Shore design by making the lower section, whichincludes the mouth, as short as possible in order to reduceto a minimum the thrust of the water on the projected areaof the resisting surface. Therefore, the first joint is very near.

It has also been difficult to raise the scoopswhen running fast. The problems of easy elevation and ofpreventing splashing have been studied with special care inthe design which is illustrated by the accompanying engrav-ings, prepared from drawings received through the courtesyof Mr. H. F. Ball, Mechanical Engineer of the Lake Shore &Michigan Southern Railway. These present a design workedout by him for use on the fast passenger locomotives of thatroad and they will also be used in freight equipment. Mr. Balldesired to meet the following conditions: A construction which would permit of raising the scoop atspeeds as high as 70 miles per hour by hand.
