During thepast few years all government legisla-tion and activity have been such as to re-tard individual initiative. As Mr. White-law Reidbrought out in his address ofalmost twenty years ago, in spite of theAmerican form of governments beingthe most expensive and inefficient, it wasthe best government on earth, for itbrought out to a greater extent individualinitiative. The advantage of developingindividual initiative far overbalanced. other defects in our form of the problems confronting thepublic today, we should take into con-sideration that the governments mis-management and inefficiency during thepast seven years have taken such form asto attack individual initiative, and thatwe cannot depend upon this factor to helpsolve present problems to the extent thatit did in the past. August. 1920 RAILWAY AXD LOCOMOTIVE ENGINEERING 251 A New Hardness Testing Machine Details of its Construction and Operation One of the best known methods ofmeasuring the hardness of metals is thatdevised by Brinell in 1900. According tothis method, a 10 mm. ball in contactwith the specimen is loaded with a pres-sure of 3,000 kilograms, and the diam-eter of the resulting depression in thespecimen is measured. By comparingthis measurement with the standardtables, the tensile strength of the materialcan be obtained, though this is not al-ways desired, as the ball test is so wellknown that specifications frequently stipu-lat
