We are standing on an old stone bridge, and are enabled to observe it closely. By a rapid, vibratory motion of the wings, it drives itself down through the water, and by the aid of its wide-spreading feet clings to and walks among the pebbles. These it rapidly turns over with its bill, searching for the larvæ of water flies and gauzy-winged ephemeræ. It searches the brook carefully downwards, sometimes clean immersed, at other times with its back out, then with the water barely covering its feet. It does not always work with the stream, as we have frequently seen him struggling against it, but retaining its position upon the bottom. Even at the present day there are naturalists who, from the examination of cabinet specimens, aver that it is not in the power of the bird to walk on the bottom of the brook, but then they know nothing of him along his native streams.
Taking advantage of two birds remarkable for their long and sustained powers of flight, experiments have recently been conducted with a view to utilising swallows and pigeons as war messengers. In this connection the use of trained pigeons is one of the oldest institutions in the world; though now that certain European Powers have trained falcons to cut down pigeons, it is said that the pigeon-post is not sufficiently reliable. In consequence a number of French savants recently approached the Minister of War, and induced him to found a military swallow-cote whence the birds might be trained. The Governor of Lille was charged to test the plan, and certain experiments made at Roubaix last year are now commanded to be repeated under the supervision of Captain Degouy of the Engineers. During the coming autumn this gentleman is to be present at a grand flight of messenger swallows; and if his report is favourable, a swallow-cote will be founded and placed under the care of special trainers at Mont Valérian. The idea of engaging swallows in war is a pretty one, as in future all European wars will have to be conducted in "Swallow-time"—when the warm winds blow from the sunny south. This arrangement will at least obviate night-watches in frozen trenches; nor is it likely that pickets will any longer be starved to death at their posts. The incident is also quoted in proof of the fact that we are nearing the time when Europe will be governed by the Parliament of Man, the Federation of the World. But, after all, the idiosyncrasies of France have a way of not being fulfilled; and the reign of the swallow will doubtless be as ephemeral as that of the brav' Général himself. In all their military operations of late the French have made considerable use of pigeons in conveying despatches; and in the Franco-German war the birds played a conspicuous part. Upon several occasions, indeed, the inhabitants of beleaguered cities looked upon the successful flights of these birds as their only hope betwixt death and starvation.
At the time the French were making trials with messenger swallows, the young German Emperor ordered extensive experiments to be carried out with carrier pigeons, the same to be tested at the Imperial manœuvres. Upon this, six of the first Columbarian Societies of Germany each offered to supply twenty-four birds, which are now in training. So we have it that the French are endeavouring to train swallows, the Germans pigeons, and the Russians falcons. Whether the falcons are themselves to convey messages, or are to be used to cut down the swallows and pigeons whilst so engaged, is not stated. The pigeon is a tried messenger, and has, moreover, some interesting and remarkable records. The claim of the swallow, on the other hand, lies all in its possibilities. In this connection "swallow" must stand in a generic sense, and include all birds of the swallow kind as well as the swift. Although, as already stated, swallows are among the most fatiguable of birds, yet one of the American species—the purple martin—would seem to be an exception, and the fact of its having crossed the Atlantic is well known. It is true that swallows attain to an immense speed in their rushes, and there is a well-authenticated instance of one having flown twenty miles in thirteen minutes. The probable speed of the swallow, flying straight and swift, is about one hundred and twenty miles an hour; its ordinary speed ninety miles. The swift attains to two hundred miles, and seems quite tireless on the wing. If swifts can be inspired with a sense of discipline; if French wars can invariably be arranged for the summer months; and if some arrangement can be made with the insect hosts to keep the upper air—then something may come of the Lille experiments. If these things cannot be, the French sharpshooter will never be asked to try flying shots at swifts rushing through the air at the rate of two hundred miles an hour. If the Russians are training falcons to catch pigeons, the Germans must train raptors to catch swallows. Here is a fact which proves the possibility. The hobby falcon, a summer migrant to Britain, hawks for dragon-flies—among the swiftest of insects—which it seizes with its foot and devours in mid-air. It cuts down swifts, larks, pigeons, and, where they are found, bee-birds—all remarkable for their great powers of flight. By way of testing the speed of flight in birds of the swallow kind, Spallanzani captured and marked a sand-martin or bank-swallow—the feeblest of its genus—on her nest at Pavia and set her free at Milan, fifteen miles away. She flew back in thirteen minutes. In striking contrast with the rate at which birds with long pointed wings fly is the fact that one of a pair of starlings (which are short-winged birds) was captured and sent in a basket a distance of upwards of thirty miles by train. It was then freed, and was three hours before it found its way back to its nestlings.
To turn from swallows to pigeons. The power of pigeons on the wing is proverbial. All trained birds of this species have two qualifications in a marked degree. The first is speed; the second long and sustained powers of flight. This proposition can be amply demonstrated, and the following are some of the most remarkable records. On the 6th of October, 1850, Sir John Ross despatched a pair of young pigeons from Assistance Bay, a little west of Wellington Sound; and on October 13th a pigeon made its appearance at the dovecote in Ayrshire, Scotland, whence Sir John had the pair he took out. The distance direct between the two places is two thousand miles. An instance is on record of a pigeon flying twenty-three miles in eleven minutes; and another flew from Rouen to Ghent, one hundred and fifty miles, in an hour and a half. An interesting incident of flight is the case of a pigeon which, in 1845, fell wounded and exhausted at Vauxhall Station, then the terminus of the South-Western Railway. It bore a message to the effect that it was one of three despatched to the Duke of Wellington from Ichaboe Island, two thousand miles away. The message was immediately sent on to his Grace, and by him acknowledged. In a pigeon competition some years ago, the winning bird flew from Ventnor to Manchester, two hundred and eight miles, at the rate of fifty-five miles an hour. As an experiment a trained pigeon was recently dispatched from a northern newspaper office with a request that it might be liberated for its return journey at 9.45 a.m. It reached home at 1.10 p.m. having covered in the meantime one hundred and forty miles, flying at the rate of forty miles an hour. In the north pigeons have long been used to convey messages between country houses and market towns; and in Russia they are now being employed to convey negatives of photographs taken in balloons. The first experiment of the kind was made from the cupola of the Cathedral of Isaac, and the subject photographed was the Winter Palace. The plates were packed in envelopes impenetrable to light, and then tied to the feet of the pigeons, which safely and quickly carried them to the station at Volkovo. Here is another interesting instance of speed and staying power. The pigeons in this case flew from Bordeaux to Manchester, and not only beat all existing records, but flew more than seventy miles further than anything previously attempted by English flyers. The winning bird flew at the rate of eighteen hundred and seventy-nine yards a minute, or over sixty-four miles an hour, and that for a distance of one hundred and forty-two and a half miles. The same club has flown birds distances of six hundred and thirteen, and six hundred and twenty-five miles. These latter, however, were several days in returning, and in their case the only wonder is that they could accomplish the distance at all. The following is still more interesting, as it entailed a race between birds and insects. A pigeon-fancier of Hamme, in Westphalia, made a wager that a dozen bees liberated three miles from their hive would reach it in better time than a dozen pigeons would reach their cot from the same distance. The competitors were given wing at Rhynhern, a village nearly a league from Hamme, and the first bee finished a quarter of a minute in advance of the first pigeon, three other bees reached the goal before the second pigeon, the main body of both detachments finishing almost simultaneously an instant or two later. The bees, too, may be said to have been handicapped in the race, having been rolled in flour before starting for purposes of identification.
The American passenger pigeon compasses the whole Atlantic ocean. The speed of its flight is approximately known; it is able to cover one thousand six hundred miles in twenty-four hours.
