The Consul of Alexandria daily sends despatches by these means to Aleppo in five hours, though couriers occupy the whole day, and proceed with the utmost expedition from one town to the other. Some years ago a gentleman sent a carrier-pigeon from London, by the stage-coach, to his friend in St. Edmundsbury, together with a note desiring that the pigeon, two days after their arrival there, might be thrown up precisely when the town-clock struck nine in the morning. This was done accordingly, and the pigeon arrived in London and flew to the Bull Inn, Bishopsgate Street, into the loft, and was there shown at half an hour past eleven o’clock, having flown seventy-two miles in two hours and a half. Carrier pigeons were again employed, but with better success, at the siege of Leyden, in 1675. The garrison were, by means of the information thus conveyed to them, induced to stand out till the enemy, despairing of reducing the place, withdrew. On the siege being raised, the Prince of Orange ordered that the pigeons which had rendered such essential service should be maintained at the public expense, and at their death they should be embalmed and preserved in the town-house as a perpetual token of gratitude. At Antwerp, in 1819, one of the thirty-two pigeons belonging to that city, which had been conveyed to London and there let loose, made the transit back—being a distance in a direct line of one hundred and eighty miles—in six hours. It is through the attachment of the animals to the place of their birth, and particularly to the spot where they had brought up their young, that they are thus rendered useful to mankind. When a young one flies very hard at home, and is come to its full strength, it is carried in a basket or otherwise about half a mile from home and there turned out; after this it is carried a mile, two, four, eight, ten, twenty, &c., till at length it will return from the furthermost parts of the country. _LETTERS._ The word _letter_ is derived from the Latin “_litera_,” of which Vossius has not decided its etymology,—perhaps, from _litum_, past participle of _linere_, to smear, as one of the oldest modes of writing was by graving the characters upon tablets smeared over or covered with wax. From this word comes that of _letters_; and, as they are more immediately connected with our subject, we incline to the opinion of Pliny that the word _linere_, to smear, is by far the most truthful definition. In this respect—that of “smearing”—it has lost nothing of its original character, if we were to judge from the appearance of many letters daily passing through the post-office. “Smeared o’er with wax” would not cause any great surprise to a modern post-office clerk if a letter presented itself with this only on it; but when in addition he could scarcely read the name through the mists of blotted ink and bad spelling, we venture to say he would endorse Pliny’s opinion, above that of all others, without the least hesitation.
