In describing the Hamilton five-spindle vertical car boring ma-chine, with three vertical and two radial spindles, on page 167of the April issue, an error was made in using as an illustrationa machine having four vertical spindles. The five-spindle ma-chine is illustrated herewith; the spindles have 20 in. stroke anda transverse adjustment of 22 in. The four-spindle machine, the illustration of which is repro-duced, was also designed for use in railroad and car shops. Itcarries four spindles in heavy housings mounted in dovetail slideson top of the heavy Column frame. The housings have a trans-verse adjustment of 22 in. by means of self-clamping and quick-moving hand levers. Each housing is provided with its owndriving pulley, driven from a countershaft mounted on the floorat the rear of the machine. This allows for the stopping of thespindles not in use by simply throwing the belt from the spindles have 20 in. stroke. They are brought down sepa-. hold material against the fence and to prevent the bits fromraising it from the table. The feed mechanism for th< table consists of reversible fric-tion pulleys controlled from the front by a convenient handlever. The power feed is generally used for moving long dis-s while the hand wheel f< ed is for accurate setting andshort distances. This machine weighs 6,500 lbs., requires 10horse-power for driving and occupies a floor space of 6 by 10 is manufactured by The Bentcl & Margedant Company, Ham-ilton, Ohio. The Railroads and the Public.—The railroads want to people the best possible service, for it is only by doing thisthat they can obtain an increase of traffic. Do not understandme as saying that the blame for this ill-feeling towards railroadsshould be placed entirely upon the people. The railroads them-selves are responsible for a share of it, but I believe that thepublic and railroads are getting closer together. Th
