Incidentally, savings aggregating many thousands of dollars annually have been effected through the suggestions and inventions of employees in the service. One of the important divisions in the postal service is that which pertains to the inspection work, much of which does not attract outside attention and only comes to public notice when some one has gotten into trouble with the postal authorities. In a large measure, inspection work pertains to the apprehension of criminals and the investigation of depredations, but that is only a comparatively small part of the division's activities. Post-office inspectors investigate and report upon matters affecting every branch of the postal service; they are traveling auditors and check up accounts and collect shortages; they decide where an office should be located, how it should be fitted up, and how many clerks or carriers may be needed. The rural carriers, for instance, must be familiar with the regulations that cover the delivery of mail, registration of letters, taking applications for money-orders, sale of stamps, supplies, etc., but the inspector must also know all of these and also be able to determine when the establishment of a route is warranted, to lay out and fix the schedules and prepare a map and description of the route, also measure the routes if the length is in dispute, inspect the service, ascertain whether it is properly performed, and give necessary instructions to the carriers and postmasters.
