Transportation by trooping and by train, or the ability of the cattle to withstand the first or the ability of the railways to handle for want of facilities, are at times matters of much consequence. _Second._--Location as applied to a position for operating, applicable to domestic or foreign works. There are several items of prime importance to be considered in selecting a location from this standpoint. In many instances a plant is established near a locality producing a sufficient quality of live stock suitable for a certain purpose, for example pigs suitable for export trade. In some instances the selection of a location is made for trade reasons, or to be adjacent to a stock yards; and in instances because property is owned in a certain locality. Where situation can be of choice, the matters for most serious consideration are sewage disposal, water supply, prevailing winds and transportation facilities. =Water Supply.=--This is of great consequence. The quantity to be used for condensing purposes, refrigerating machinery operation, for cleansing, and in the regular course of business, is a very large amount, and if purchased from water supply corporations or municipalities, at prevailing rates, become a burdensome item of expense. The principal use for water can be classified under three headings: _Boiler Purposes_--This naturally will be selected from available sources based upon fitness, irrespective of cost. _Condensing_--First, for refrigerating machinery ammonia condensing and for steam engine condensing, in conjunction with the production of power and operating steam engines on refrigerating equipment. For this purpose cold water is desirable. If it can be obtained from wells it is the best practice, owing to such water usually being of low temperature. However, the cost of production must be considered, and that calls for engineering knowledge as to relative conditions. Usually, unless the surface water be in large quantity and available from a stream, the wells prove economical unless the water must be raised from great depths involving air lift pumping. There are instances, however, where turbidity makes water from streams undesirable and where well water is unobtainable, and in instances of this kind use of settling basins, reservoirs and cooling towers is resorted to. _For Cleaning and Other Purposes_--The water for cleansing purposes, for food products, fats and premises, should be clean and free from contamination that render it unfit for potable uses.
