Denny & Company have built a considerable number ofquadruple-expansion engines of the same general type. ♦ COLUMBIAN EXPOSITION NOTES. The great transfer table, which is to be used in runningthe locomotives and coaches of the trans])ortation exhibiton to their respective tracks, is now completed. It is about70 ft. in length, and will travel on seven pairs of ^ I fit QUADRUPLE-EXPANSION MARINE,; DENNY & COMP.\NY, DUMBARTON, fSCOTL.^ND. The tracks upon which it will ply are situated about 3 than the tracks to be occupied by the exhibits. Thisallows the track on the surface of the transfer table to comeon a level with those on which the exhibits are to beshunted. Extending about three-fourths of the length of the trans-portation annex is a cut in the flooring about 3 ft. in depthand 70 ft. in width. Seven rails are laid its entire length,and it is on these that the transfer table will travel. Tlie table will have a carrying capacity of 100 tons, fitwill be operated by electricity, and one man will have com-plete control of it. According to the amount of weight onit the table can be made to travel back and forth at a speedvarying from 130 ft. to 335 ft. per minute. A dynamo of 30 operates the machinery. Thedynamo and gearing are on a small platform attached to thecar at its cente
