The February issue of Field and Shop News, published by the Pittsburgh Meter Company, Pittsburgh, Pa., has been received. It consists of sixteen pages, filled with interesting matter in connection with the work of the employees of the company, by whom it is edited.

The Joseph Dixon Crucible Company have sent in the February issue of Graphite, which they publish monthly. The issue is up to the usual standard of this newsy little house organ, from an artistic and typographical standpoint.

The double-helical speed-reducing gear, as used for stepping down from the high speeds of steam turbines to speeds suitable for direct-current generators, large centrifugal pumps and fans, rope and belt drives, etc., was first introduced about twentyfive years ago by the late Dr. De Laval. This type of speedreducing gear has subsequently been developed by the De Laval Steam Turbine Co., of Trenton, N. J. That company has now issued a 32-page catalogue describing standardized geared turbine units. The new publication describes the details of construction of turbines and gears and also various turbine-driven auxiliaries, including circulating pumps, boiler feeders, etc.
