It is no small achievementto change radically time-honored methodsof the mechanical trades in the space ofless than a generation, especially when itis realized that the machines in questionwere far from being perfect when theywere first taken hold of by these men. This brief sketch illustrates the newnessof the air-motor as a practical machine,and its rapid extension to many lines ofwork. The early motors were unwieldy and in-efficient to such an extent that there wasgreat difficulty in persuading men to use them the stimulus to make a machinethat would not only do the work—do hand work in very close quarters—but that would also be easy and convenientto use—that would save, not increase, themans effort. Realizing the necessity ofsecurmg the hearty and willing co-opera-tion of the workers, shop officials havebecome more critical, have instituted tests
