under stress of wind. lines, it becomes cheaper to carry it in barges to the powerstation site. The plant was, therefore, designed more particu-larly to deal with water coal, though certain provisions weremade in the design of the tower that will admit of the devel-opment of the power station for handling railroad coal direct-ly from the cars should it ever be required in the future. The complete coal and ash conveying plant, which is shownin one of the half-tone engravings, may be said to consist ofthree parts, the coal hoisting tower, the cable railroad, whichcarries the coal from the tower to the coal pocket and its sup-porting bridge, and the ash bin structure, which is so ar-ranged that it forms a part of one of the piers of the cablerailway bridge. This level bridge is 107 ft. above the dock, andis at about two-thirds the entire height of the tower, whosetop is 170 ft. above the dock. April 7, 1906.)

540 STREET RAILWAY JOURNAL. (Vol. XXVIL No. 14. The hoisting engine and apparatus is located within thefour-corner columns of the hoisting tower in an enclosure25 ft. above the dock and having a height of 14 ft. Thetower is of the one man type, and has a capacity for 400long tons of run-of-mine bituminous coal in five workinghours. Hitherto, the single operator of a one-man towerhas generally been stationed directly under the trolley boom,which, at the height adopted in this case, would necessitateshutting down during foggy weather. To avoid this con-tingency the mechanism controlling the operation of thebucket was designed to stand the operator at an elevationonly a short distance above the barge then being unloaded.Another new element in the design partly introduced to facil-itate this, is a third hoisting engine for opening and closingthe bucket, in addition to the two engines ordinarily used, onefor hoisting it, and the other for trolleying it along the boom. The coal is hoisted i
