In the meantime changes in managementtook place and the steam turbine became a successful competitorwith the steam engine of the reciprocating type ordered, and itspossible future use made it prudent to design the system with thisin view. These considerations as to turbines formed the key ofthe situation in regard to the general design and arrangement of thestation on the lot, and to some extent of the exterior and determinedespecially the electrical controlling scheme. The Missouri River plant has three 4,600-h. p. .Mlis-Chalmers verti-cal cross compound condensing engines and 18 Babcock & Wilcox578-h. p. double deck boilers with Green chain grates. This is onlya portion of the present boiler capacity of about 24,000 b. h. p. If. FIG. --PLAN- OF MISSOCRI RIVKR ST.\TI()N. The station site was a blufl, anil many old buildings, with earthto a depth of from 25 to 50 ft., were removed, and the earthdeposited on the river bank hydraulically. .X city sewer formed aconvenient channel for this earth as it lay on the bed rock whichformed the basement level of the station. This rock was reached inNovember. 1902. after two or three months work, the starting ofplans dating from July, 1902. The relative elevation of the river water levels, high and low,and location of the building site, tracks, etc., are shown in Fig, 3,and it will be seen that a plane 25 ft. below the lowest street levelwas chosen as the basement floor level, for the location of pumps,condensers and piping determined this elevation as the proper onefor the engine room basement and in the boiler room a greaterdepth was not necessary, except for pumps and hot wells.
