Added to all this is the necessity for repeating this process when destined to any point not directly reached by the originating office. Over and over again have many of the messages left in the hands of telegraph companies to be translated or re-written before they reach their destination; very different from the sealed letter, which needs but the toss of a practised hand to change its route and put it under the cover of a new bag. The difference between the use of the post and telegraph is well shown by the practice of the Western Union Telegraph Company, _which requires all of its employees to use the mail, instead of the telegraph, in every case where the interests of the company will not suffer by the delay_. All check errors, and discrepancies in accounts, are settled by correspondence through the mail, where the same might be done more readily, though at far greater expense, by the use of the wires. Now, if the company owning the lines, and working them, can better afford to pay the postage on its communications, than to block up the wires with its own free business, it shows a very radical difference between the expense of transmitting matter by steam, or horse-power, and doing the same by electricity. COLLECTION AND DELIVERY OF TELEGRAMS BY LETTER-CARRIERS IMPRACTICABLE. The plan proposed for the collection and delivery of telegrams by letter-carriers is equally impracticable. The rapid and safe delivery of messages is the great difficulty with which the telegraph companies have to contend, and the amount paid for this service forms a very material portion of the expense attending the operation of the system. How would this service be performed if left to the Post-Office Department? In 1865—the last year containing the statistics of the number of letters sent through the United States mail—the Postmaster-General estimates the number of letters transmitted at 467,591,600. No statement of the total number of letters delivered by carrier in the United States is given in the Postmaster-General’s reports for 1865 or 1866, but he states that the number of cities at which free delivery is established is 46, and the total number of carriers, 863; that 582 carriers are attached to ten offices, from which are delivered 38,060,009 letters. If the remaining 281 carriers, who are distributed among 36 offices, deliver as many in proportion, we have a total of 56,446,004 letters delivered for the year, or about nine per cent of the whole number transmitted through the mail. This does not present a very flattering result, and does not argue very favorably for the satisfactory delivery of thirteen millions of telegrams, through the same channel, at over 4,000 offices! Compare with these meagre results the operations of the British Post-Office, which employs 11,449 carriers, and annually delivers 705,000,000 letters.
