The Locomotive . on trips in this agreeable manner. On the other hand, Inspector W. H. G. Slaymaker of Jackson,Mississippi shows a decided preference for more modern modes of travel. InspectorSlaymaker has hadexperience in avia-tion and his interestin the subject con-tinues. While theautomobile usuallytakes him on hisrounds, he at timesis fortunate enoughto have an airplaneat his disposal. Thismeans of travel notonly reduces the timespent in going andcoming, but under certain conditions has expedited the work in anotherway. For instance, the inspector, in trying to keep track of portableboilers, often finds himself in a position to sympathize with the hen who never finds things where she lays them. Portable sawmill boilersare seldom found where they were at the time of the last inspection, andsometimes are rather evasive. In the woods is often the only such cases the advantages of an airplane observation are apparent. Ofcourse the opportunity of flight holds no inducement for the Inspector Wm. H. G. Slaymaker (Right). Riveting Pressures.* THE pressure applied to rivets in the operation of riveting up andthe length of time the pressure is sustained upon the rivets aretwo important factors which materially affect the eflficiency ofthe riveted seams of boilers. In this country [England], these ques-tions have received considerable attention, but there is a wide differ-ence in the actual practice of various boiler makers. The followingtranslation from a French contemporary expresses to some extentContinental opinion regarding riveting pressures, which it may be notedare appreciably less than is the practice in this country: — •Extract from an article by V. Kammerer. in the Bulletin of the French Association ofBoiler Owners, January, 1925. Reprinted from Vulcan. 14 THE LOCOMOTIVE.
