The theory of the use of foreign cars is that they are permitted to run through to destination with through freight, on condition that they shall be promptly unloaded on arrival at destination; that they shall be returned at once to the home road, being loaded on the return trip if suitable loading is available; but by no means allowed to be used in local service, or loaded in any other direction than homeward.

The practice of many agents, and many roads, too, unfortunately, is hardly in keeping with this theory. Agents, especially if not closely watched, are prone to put freight into any car that is at hand, regardless of ownership, being urged to such course by the importunities of shippers and, at times, by the scarcity of cars. Frequently such irregularities are the result of pure carelessness, agents using foreign cars for local shipments, simply because they are on hand, rather than call for home cars which it may take some trouble and delay to procure. In this way at times a large amount of local business may be going on on one part of the road in foreign cars, while but a few miles distant the company's cars may be standing idle. The Car Accountant from his record can at once put a stop to this, and prevent its recurrence.

Another valuable use to which the Car Accountant's Office may be put is to trace and keep a record of the movement of freight, locating delays, and tracing for freight lost or damaged. By a moderate use of the telegraph wire the Car Accountant can keep track of the movement of special freight-trains concerning which time is important, and so insure regularity and promptness in their despatch and delivery. From the mileage records may be obtained the work of each engine in freight service, the miles run, the number of loaded and empty cars hauled; and by considering two, or perhaps three, empty cars as equivalent to one loaded car, the average number of loaded cars hauled per mile is obtained. The information is often valuable, as on many roads the ability of a Superintendent is measured to a considerable extent by the amount of work performed by the engines at his command.

In many other ways the resources of the Car Accountant's office will be found of the greatest value to the Superintendent. When the office is once fully organized and systematized, and all in good working order, the Superintendent will find that his capacity for control of his cars has been more than doubled, while the demands on his time for their care has been really lessened. He has all the information he needs supplied at his desk, far more accurate than any he was ever able to secure before, and in the most condensed form; while, at the same time, he will find his freight improving in time over his line, his agents will have cars more promptly and in greater abundance than ever, and last, and most gratifying of all, his monthly balance-sheets will show a steady decrease in the amount his road pays for foreign-car mileage, until probably the balance will be found in his favor, although his business and consequent tonnage may have increased meanwhile.

USE AND ABUSE OF CARS.

A package of merchandise can be transported from New York to Chicago in two days and three nights. This is repeated day after day with all the regularity of passenger service. So uniform is this movement, that shippers and consignees depend upon it and arrange their sales and stocks of goods in accordance therewith. Any deviation or irregularity brings forth instant complaint and a threatened withdrawal of patronage. This is true of hundreds of other places and lines of freight service. To accomplish it, there is necessary, first, a highly complicated and intricate organization, and, next, incessant watchfulness.
