After the Manager figures up from these totals handed him by the different bank clerks, he finds that certain banks brought more than was brought against them, and that certain other banks brought less than was brought against them. In other words certain banks have "lost" at Clearing while others have "gained" and at a later (designated) hour of the day, the debtor banks pay in their losses at the Clearing House and the creditor banks receive their gains, the total losses and gains, of course, exactly offsetting each other. While the systems employed at the Clearing Houses of the various cities of the United States may vary in some particulars, they are all founded on the principles stated in the preceding paragraphs. These principles have been so perfected that the clerks from the different banks are at the Clearing House for a few minutes only each day. The Manager imposes a fine of several dollars on the bank for every mistake in calculation its Clearing House clerk makes; also for tardiness. To return to the checks which have been brought back from the Clearing House. If, on examination, the Paying Teller has discovered any forgeries, or irregular or missing endorsements, or anything suspicious about any checks; or if the bookkeepers have found that any check overdraws the account of the depositor, the bank has only until the close of banking hours to return such checks and collect from the banks that sent them through the Clearing House. So the examination of these checks must be made carefully and very quickly. The "_Clearing House Association_" in your city is what might be called a Mutual Aid Society, which the banks have organized for purposes of mutual convenience and protection. This Association pays the expenses of the Clearing House; the Manager's salary; the rent; etc. It adopts rules and by-laws and fixes fines and penalties for breaking them. But it is not an incorporated body and can not sue or be sued.
