In one aspect the process of sortation bears some resemblance to digestion. This is observed in connection with the strange courses which letters run if, by a first misreading of the address, they happen to get out of their proper line or direction. A day seldom passes but some letter addressed to Edenbridge in Kent reaches the city of Edinburgh, either from London or some other English town. There is, of course, a strong resemblance between the names of the two places as written, yet the missent letters must have passed through the hands of two or three sorters before reaching Edinburgh. But though this might seem to suggest carelessness, there is this to be said, that whenever a letter for Edenbridge gets out of its own course, and into the stream of letters for Edinburgh, the sorters have a predisposition to assimilate it as an Edinburgh letter, and so it gets forwarded to that city. The same thing applies in regard to letters for Leek, Leith, and Keith, and for Musselburgh and Middlesborough--especially when, as is too often the case, the writing is not good; and many other similar instances might be given. Letters for Fiji frequently reach Edinburgh from London and the South, being missent as for Fife in Scotland; and we have it on the authority of the Colonial Postmaster of Fiji, that numbers of letters, papers, &c., directed to Fife, reach the Fiji Islands. Two letters posted at Hamilton, Bermuda, and addressed to Edinburgh, Saratoga Co., N.Y., were recently observed to perform a curious circuit before reaching their destination. Instead of being sent direct to the United States from Bermuda, they were forwarded to London in England; and here, getting into the current of inland correspondence, they were sent to Edinburgh in Scotland. At this stage their wild career was stopped, and they were put in proper course to recross the Atlantic. It is near the truth to say, that similarity of names and bad writing are the causes of very many of the irregularities which befall letters in their transit through the post.
The intellectual superiority of man has enabled him to bend to his purposes the various physical powers of the lower animals--as, for example, the strength of the ox and the fleetness of the horse--and his observation has taught him also to turn to his use some of the instincts of the lower creation, though these gifts may lie hidden beyond the reach of his understanding. Thus the keen scent of the bloodhound, and the sense which enables the "ship of the desert" to sniff the distant spring, are equally become subservient to the interests of man; but it is with reference to another instinct not less remarkable that this chapter is written--the homing instinct of the carrier-pigeon. This gentle bird has long been known as a messenger capable of conveying news from one place to another over considerable distances. It is asserted that "Hirtius and Brutus, at the siege of Modena, held a correspondence by pigeons; and Ovid tells us that Taurosthenes, by a pigeon stained with purple, gave notice to his father of his victory at the Olympic games, sending it to him at Ægina." In Persia and Turkey pigeons were trained for this service, and it is stated that every bashaw had some of these birds reared, in order swiftly to convey news to the seraglio on occasions of insurrection or other emergency. In somewhat modern times the best birds were said to be those of Aleppo, which served as couriers at Alexandretta and Bagdad; but many years ago their services in this line had to be given up, owing to the Kurd robbers killing the pigeons in the course of their journey. It does not appear, however, that, until quite recent times, any great use has been made of these birds by Western nations, at any rate under any extended scheme for commercial or peaceful ends. Yet, by what may seem an incongruity, the dove, which is _par excellence_ the emblem of love and peace, has of late years been trained for purposes of war by the great Continental States; and it is impossible to predict how far the fate of nations may be determined hereafter by the performances of these naturally harmless creatures. The following particulars from one of the annual reports on the Post-office will show to what extent service was rendered by carrier-pigeons in keeping up postal communication with Paris when that city was invested during the Franco-German war of 1870-71:--
