house, engine-house, hoppers and towers are also clearlyshown. The steam plant consists of two 150-11.P. boilersplaced in a house located on the transverse centre line of theplant, and from which the steam is piped to the several en-gines. The furnaces are designed for burning screenings anddust on the McClave grates with steam blowers that have beenso successfully used in the anthracite mining regions for burn-ing culm. In each of the four engine-houses there is a 100-H7P. engine for driving the machinery. In fig. 2 we have an outline of the trimmers. The trussesare so designed that a certain number of bents at each end arestandard, so that they are available for use with any span oftrimmer that is likely to be erected, the intermediate bentsbeing put in as the occasion may demand. It will be noticedthat the angle made by the trimmer girders with the horizontalis about 27°. The contractors have found, as the result oftheir experience, that this (is nearer the angle >t which loose

The system of storing tin coal is very simple. Beneath theentering track, and directly in a line with the centre line ofthe trimmer as shown in fig. 1, there is a hopper into whichthe cars arc dumped, and which has a capacity sufficient totake the whole load of the car. A chute in the hottom of thehopper, controlled by a sliding door, delivers the coal by grnv- of the Conveyer trough, it carries the point of discharge out and up, the process being repeated until the pile is completed and the floor full. These conveyers are to run at a speed of800 ft. per minute, and will have a capacity of 8 tons per minute.Fig. 3 shows in some detail the plan of the pivot end of thereloader. This portion of the apparatus consists of an armvarying in lengthaccording to the size of the pile to be at-tacked, asglven in tbe*aimensions marked onfig
