_Salt Spaces, etc._--In this instance, but which rarely occurs, the city’s main sewer system is located at a deep level, which affords proper drainage and permitted the construction of two cellars. There are, therefore, two stories practically under ground. This is a decided advantage from the standpoint of radiation exposure, and it also affords an opportunity to provide salt storage and cooperage stowing spaces on two levels adjacent to the railroad tracks. It further provides a means for securing a connecting tunnel below the track level, thus providing facilities for a perfect interchange from all cellar departments. Of equal consequence is the opportunity to pass all pipes for water, steam and refrigeration, power and lighting wires, as well as products, from one department to another. This makes for a low upkeep cost, little exposure, less radiation and greatly reduces the annual upkeep. _Power Department_--The boilers were placed on a floor level with the basement. The coal pocket into which coal is dropped extends to the sub-basement level, providing a comparatively large coal storage. At the sub-basement level are the ash collecting bins. From this level are provided elevators of the continuous bucket type for raising the coal and ashes to tanks provided for storage, from which the coal and ashes gravitate to the furnaces and disposal cars respectively. The engine foundations extend to the sub-basement level, with the main engine situated upon the basement level. The pumps are located in part on the lower level. All pipes and wires leading to the operating department are carried through the sub-basement, permitting the arrangement of all exhaust and steam piping beneath the engine room floor. _Gravity System_--Attention is called to the fact that in the rendering department, for example, the products in their steps of manufacture are handled by gravity entirely until the finished dried fertilizer is produced, which has to be elevated to the ground level for car shipment, or for wagon delivery. The same features are true of the abattoir, hides and tallow in casks only, requiring the use of elevators for shipment. [Illustration: FIG. 8.--PLANT NO. 2, GROUND PLAN FOR COUNTRY PACKING HOUSE.] =Plant No. 2.=--This plant was designed for a country point where the shipping by local freight cars or the city delivery was quite limited; where the major part of the product would be shipped by car, and where provision was made for quite an extensive growth. The capacity as designed being four hundred hogs and fifty cattle daily, with a complementary quantity of calves and sheep. _Loading Facilities_--Again the three railways are provided for convenience in loading and for facilitating switching and icing.
