The committee takes pleasure in acknowledging the assistanceof the parties who furnished data. Piston Rods and Crossi^eads. Discussion.—W. F. Kiesel (Penn.) stated that 10,000 poundsper square inch was allowed for the maximum pressure in thesmallest section of the rod in his office. By the use of largekeys and careful workmanship piston rod breakages on rodsdesigned on this basis had been practically eliminated.
