As it is sometimes desired tohave several welding circuits connected to one generator, acontrol panel is provided for each circuit. Each panel can be located at the most desirable place. Metal or carbon pencilwelding can be done from any of these panels, independentof all others, and one or more arcs can be operated simul-taneously. The accessories consist of a carbon holder anda hood for protecting the operator, together with a shield anda metal pencil holder for each welding circuit. This equipment is the result of eight years experience in.

BRONZE BEARING METAL FOR TRUCKJOURNALS A bronze bearing metal composed of 65 per cent copper, 30 percent lead and 5 per cent tin, has recently been tested by the Balti-more & Ohio. .A 22 lb. brass, used without babbitt was placedunder the tender of a Pacific type locomotive. After the enginehad run 51,000 miles an examination of the bearing was was said to have been worn 1/32 in., and had made this mile-age without running hot at any time. Other bearings on tlietender were said to have been re-babbitted six times each. For mill purposes, this bronze, which is treated in crucibles,may be hardened into what are claimed to be very superior millbrasses. A test of this nature is reported with two 75 lb. millbrasses used under the rolling table of a 108 in. plate mill, theminimum weight of which is estimated at 10,000
