This foundation was to bear a heavy load, so it wasbuilt up solidly of concrete in the following formula: One part Portland cement. Two parts Louisville. Four parts granite rock. This was laid to a depth of 13 feet and covered withblue lime stone above cap stones, weighing 60,000 pounds,making the total foundation weight 750 tons.

Previouslyto this performance, however, an order had been placedwith Rankin & Fritsch, engine builders, of St. Louis, forone 800-horse-power tandem compound condensingengine, designed by the Rankin & Fritsch engineersafter specifications furnished by Chief Engineer Elliott,of the Consolidated Company. The cylinders of thisengine are 22 inches high pressure and 40 low pressureby 48-inch stroke. Coupled to the shaft of the engine isa Westinghouse 500-kilowatt railway generator, designedfor 90 revolutions per minute. A WATER WEIGHER. The awful mendacity of water meters and the necess-. ity of weighing water to determine cost of power, hasdriven the inventive genius of the power plant to thedivising of the water weigher illustrated. The automatic weigher is contained in a rectangularwooden box, 2 by 3 feet in dimension and 8 feet longInside are two barrels, one on each side of a pair of the barrels are in mid-stroke the levers are horizontaland forged to them is an upright on which at the end is thecounter-balancing weight. Across the tops of the barrelspasses a water pipe which comes from the discharge pipeof the condenser. In the pipe are two valves which areopened by the barrels automatically as they come to tlietop, and at the bottom of the barrels, two similar valvesdischarge the water as the barrel sinks. The lattervalves are the larger, in order to make it certain that allwater is discharged from one barrel before the other one drops; it is not necessary to change the weight in orderto adjust the barrels, but simply to alter
