Collection, Facing, Stamping, Sorting, Conveyance, Stamping,[617] Sorting, Delivery; and in the case of those packets which pass through more than one office there are, for every such office, the additional operations of sorting and conveyance.[618] The bags are conveyed between the various post offices by mail-van (horse-drawn or motor), by mail-cart, by railway, or in a few cases by carrier-cycle, tricycle, or motor-cycle. The vans, carts, or cycles of course convey the bags from office to office, but when the bags are sent by railway it is necessary to provide for their conveyance to and from the railway stations. This is largely done by mail-van, mail-cart, or carrier-tricycle; but in a great number of cases throughout the country, where only two or three small bags are concerned, their conveyance between the station and the post office is provided for by cycle postman or "runner" service; that is to say, the bags are fetched or taken by a postman or porter. COST In order to ascertain the cost of dealing with postal packets of the various classes, the relative cost, and the actual cost, of the various operations must be ascertained, and all general charges apportioned. The cost of the "postal" service, shown in Table B,[619] i.e. the cost of the whole of the services controlled by the Post Office, less the cost of the telegraphs and telephones, may be grouped, as shown in Table C, under the following main headings:-- (1) Cost of Staff, (2) Cost of Conveyance of Mails, (3) Cost of Buildings, (4) Cost of Stores, and Miscellaneous Expenditure. STAFF Since parcels are, to a considerable extent, dealt with separately, it has been possible to estimate the relative cost of the manipulative services in regard to parcels on the one hand, and all other postal packets (letters, postcards, halfpenny packets, and newspapers) on the other. The ratios of cost are shown in Table D, and the total cost of the manipulative services in respect of parcels calculated on this basis is shown in Table F.
