Those who have studied the subject ofproducing surfaces which are round, oras nearly so as can be had in practice. Russian Examination of TravelersBaggajfe. \ dispatcli from St. Petersburg gives-the interesting information that the ex-amination of passengers baggage at thefrontiers will be much stricter in the fu-ture than it has been in the past. Thewriter has twice had his baggage exam-ined at Russian frontier stations, and hecould imagine of nothing more thoroughthan the examinations that ONE OF THE MII,HOLI,AND ^ILS. know that it is necessary to finish bygrinding. But this has always been con-sidered as an expensive refinement, andwe have, in many cases, put up withseven-sided piston rods left as they comefrom the lathe or improved (?) by filing. The Norton Grinding Company,whose grinder we illustrated in the issueof June, 1901, has succeeded in provingthat the cheapest way is to grind in aheavy machine built especially for thework, and should have no difficulty insecuring converts to their way of makingrods, now that they have disposed of thehaunting specter of increased cost. Their plan of procedure is to take aroughing cut in a heavy lathe with a feedof from 6 to 8 per inch, and then put therod directly on the grinder for requires less time than turning tosize in the lathe, and, of course, proditcesan infinitely better job.
