nest and all, and left the poor missionary to seek for new companions.

Down among the coral-reefs in the Southern Pacific you meet with other bird structures, which in their way deserve equal attention. Here the seaeagles build their nests, always, if possible, in the same islet, and, if there be such a convenience, on the same tree. On a small wild flat in the ocean, too confined to allure inhabitants, and apparently too arid for vegetation, there grew nevertheless one tree, on which a pair of fishing-eagles erected their dwelling. There these lords of the waves, contemplating their vast empire, sat aloft in their eyrie, male and female, looking at their eggs, and dreaming of the future. Our readers will remember the Raven's Oak, which the woodman, whose brow like a penthouse hung over his eyes, felled and floated down the course of the river. So it was with the tree of the fishingeagles; some savage applied his axe to the stem, and down it came, though, it is to be presumed, not while the young eagles were in the nest, for the mother did not break her heart, neither did the father follow the timber with vindictive pertinacity. On the contrary, having consulted his helpmate, he took up his lodgings in a bush, and there provided as well as he could for the support and comfort of his heirs and successors. There might be tall trees at no great distance, there might also be islands larger and prettier; but he was born on this sandy flat; he therefore loved it, and stuck to it, and, had it not provided him with a bush, he would have built his nest on the sand. Such, over some creatures, is the power of locality. The higher the nature, the more extensive become the sympathies, so that to some it is enough if they can rest anywhere on this globe. They love the planet in general, but would like, if they could, to make a country excursion from it to Jupiter, Sirius, or Canopus, just by way of exercising their wings.

We have seen the humming-bird building in a little garden shrub, the

tailor-bird in the folds of a leaf; but there is one of their family which selects a far more extraordinary situation, in order to place its young beyond the reach of vermin. Selecting the tallest tree within the range of its experience, it weaves for itself a sort of long pouch with a narrow neck, and suspends it to the point of a bare twig some sixty or seventy feet from the ground. There, in its pensile habitation, it lays its eggs, warms them into life, and when the callow brood begin to open their bills, feeds them fifty or sixty times in the day with such dainties as their constitutions require. This bird is the Aplonis metallica, about the size of a starling, with plumage of a dark glossy green, interfused with purple, which gives forth as it flies bright metallic reflections. The aplonis is gregarious, like man, since it loves to build its nest in the close neighborhood of other creatures of its own species, so that you may often behold fifty nests on the same tree, waving and balancing in the air. On the plain beneath, the aplonis sees from its nest the long necked emu flying like the wind before the hunter, immense flights of white pigeons, or the shy and active bower-bird constructing its palace, four feet long by almost two feet in height, where it eats berries with its harem, brings up its offspring, and, darting hither and thither before the savage, seeks to allure him away from its home. All the shrubs, and vines, and low thickets in the vicinity are haunted by perroquets no larger than sparrows, whose plumage, gorgeous as the brightest flowers, may be said to light up the woods.

The only European bird that builds a pensile nest is one of the family that we familiarly denominate tom-tits. This liliputian architect is as choice in his materials as he is skilful in the arrangement of them-his bases, his arches, his metopes, and architraves consist of cobwebs, the finest mosses, the most silky grasses, which are woven, and twisted, and matted together, so as to defy the drenching of the most

pitiless storms, while within, his wife and little ones recline on beds of down as soft as the breast of a swan. Scarcely less genius is displayed by the magpie, which, having constructed its dwelling with extraordinary care, covers it with a sheath of thorns, which, bristling all round like quills upon the fretful porcupine, effectually defend it from the approach of insidious enemies. The portal to this airy palace is at a little distance scarcely visible; but if you diligently observe, you will perceive the magpie dart swiftly between the thorns, and disappear beneath his formidable chevaux-de-frise. To this stronghold he sometimes carries his strange thefts--his gold and silver coins, his spoons, his sugar-tongs, and any other bright article that strikes his fancy. Birds of the dove kind are proverbial for the slovenly style in which they provide for their families. Putting together a few sticks, which form a sort of rack to support their eggs, they think they have done enough for posterity, and forthwith lay without scruple upon this frail cradle. It may be fairly conjectured that they say to themselves: "If man will eat my eggs, my young ones, and me, upon him be the charge of seeing that I have decent accommodation." In the same spirit act all the barn-door fowls, hardly taking the trouble to find a soft place for their eggs, but laying anywhere, like the stone curlew. This reckless depravity of the maternal instinct has generally been attributed to the ostrich as well as to the domestic hen-but unjustly. She lays, it is true, her eggs in the sand, but not without knowing where she puts them, and not without visiting the same spot daily to lay a new egg, till, as the French say, she has finished her ponte. If the case were otherwise, how could we account for finding all her eggs together? Nature has informed her, that in those warm latitudes in which she shakes her feathers, it is quite unnecessary for her to squat upon her eggs, which the solar heat amply suffices to hatch; indeed, so scorching is the sand of the de

sert, that if she did not lay her family hopes tolerably deep, her eggs would be roasted instead of hatched. To the superficial observation of man, the surface of the desert looks all alike— smooth, undulating, or blown up into hillocks; but the ostrich's practised eye is able to detect the minutest elevations in the arenaceous plain, so that she can go straight to the spot where her first egg has been left, to deposit a second and a third close to it. Indeed, the Arabs, who habitually traverse the waste, sometimes rival her in keenness of perception, and take forth her treasures, while in maternal confidence she is scouring hither and thither in search of food.

The

To many others among the inferior animals, man deals forth his unthinking reproaches. To the cuckoo, for example, he objects to her habit of obtruding her egg or eggs into other people's premises, and leaving them there to be hatched by sparrow, wryneck, or starling, as the case may be. But while bearing thus hard upon the cuckoo, he forgets the terrible curse, under which, like another Cain, she walks about the earth, urged forward by some resistless impulse, and condemned to the eternal repetition of two analogous notes-cuckoo, cuckoo. What do those syllables mean? Abbé de Nemours, who devoted twenty years to the language of birds, or one of the original doctors of the Hellenic mythology, might perhaps have explained, but has not; so we must be content to regard as a mystery the secret of the cuckoo, which in some respects resembles those ames damnées which fly for ever over the Black Sea, according to inconsiderate tradition, for if they never paused to build nests or lay eggs, it must have been all over with them long before this time. The cuckoo has some odd tricks which have seldom been noted; for instance, she seems to find out some small bird's nest, say, in a hole in the wall, too small by far for her to enter. In this case, she squats upon the ground, lays her egg, and then, with bill or claws,

takes it up, and pokes it into the hole, after which she flies away, shrieking her awfully monotonous song. In a forest in France, we used day after day to watch this smoky-blue traveller, as, in the dawn of a summer's morning, she flew across the leafy glades, or down the glens, resting her weary feet for a moment on some giant bough, and then shooting away through the soft green light, repeating her strange and ominous cry. What is the original country of the cuckoo?

Has she

any original country? Or is she not one of those wretched cosmopolites who know no attachment to any hallowed spot, no love or knowledge of parents, having been brought up by strangers, who regarded her from her birth as an ugly changeling, thrust by some evil spirit into their nest? Surely the cuckoo is to be pitied, since she knows no home, has never seen a hearth, or experienced the soft care of fabricating a nest or hatching an egg.

SOME one has said that rivers are the great moving highways of the world. In the earlier ages, when, from a restless and feverish impulse, whole nations became nomadic, their migrations were doubtless influenced by the rivers lying in their track. History tells of barbaric people that wandered around the Euxine and along the banks of the lower Danube found their way to central Europe.

Before the discovery of the Cape of Good Hope, rivers, and especially the Rhine, played a considerable part in that extensive commerce which found its way from India to the cities of the Hanseatic League. Weary caravans brought the spices, gems, and rich fabrics of the East to the shore of the Mediterranean, whence they were carried westward mainly by Venetian traders timidly skirting the coast in their frail barks, venturing up rivers or making long journeys wherever the prospect of traffic invited. The old castles on the Rhine were built by feudal robbers, who were wont to descend from their strongholds to plunder merchants travelling on this great thoroughfare of medieval commerce.

In time they were induced to forego the chances of occasional booty for the payment of a stipulated toll. Doubtless the princely Hohenzollern could trace back their genealogy to the feudal high-toll barons of the Rhine, who furnished the original idea of the modern Zollverein of Germany. La mer, c'est l'empire, and, after the great maritime discoveries had opened a new route to India, it, in good part, diverted that distant commerce from the rivers, which the ocean reaches like shining arms over the continents as if to grasp dominion. As the elements of modern civilization became developed, societies crystallized, and the nationalities hitherto disturbed by migrations and conquests settled down where we now find them, rivers came gradually to serve their legitimate purpose of internal and international communication—a purpose resembling that which they fulfil in the physical economy of the earth. They are the veins which bring back to the ocean, through innumerable brooks and rills, seeming to have their sources in the ground, yet having unseen springs in the air, the moisture that the sun has already drawn up

from the seas in invisible buckets, and wafted away in shining clouds to be poured out in rain or dew upon the thirsty hills.

Our own country, however, furnishes the best illustration of the importance and use of rivers. Its great physical features, of which the river system is perhaps the most striking, seem to make it a fit arena for those wonderful triumphs over the elements and the forces of nature which it is our privilege to enjoy. Their vastness would have intimidated races of men, weak and cowardly from long habits of servility, superstitious, torn with fierce passions and hatreds, and able to contend with the fatality of material things only on that diminutive scale afforded by the physical conformation of Europe.

The traveller descending the lower Danube finds the ruins of old Roman towns, Trajan's way cut for a distance of thirty miles in the steep solid rock of the Carpathians for the passage of his Roman legions, and, below the Iron Gate, the piers of Trajan's bridge, erected by him for the same purpose nearly eighteen centuries ago. Hardly less remarkable are the memorials of the bloody wars between the Christians and the Turks, the places made memorable by the campaigns of Eugene and Suwarrow and the Eastern war. But, excepting now and then a walled town, there are to be seen comparatively few habitations of men, and none of that active, sleepless life which lines the banks of our great rivers.

There are no richer plains in the world than those of the lower Danube. Why is it that the pent-up millions of Western Europe do not find their way thither, as in the time of Trajan vast multitudes emigrated from slavery impoverished Italy to that Eldorado of the Roman world? The very facility afforded by the river for hostile inroads has driven or kept the inhabitants from its banks, and to a great extent left them desolate wastes. The feverish restlessness which once made barbarous nations nomadic now seizes upon the individual; and a constant

stream of immigration, oppressed by the despotisms of the Old World, bursts forth in the midst of us like a new fountain of Arethusa.

And in our own country the astonishing facilities of communication afforded by the telegraph and long lines of railroads seem to detract somewhat from the importance of rivers. We can only appreciate their value when we think of them in connection with the toil requisite for subduing the wilderness and laying under contribution the resources of our country. How earnestly and bravely our forefathers battled in this warfare, one generation taking up the task where it was left by another, so as to subdue the land and render possible such marvels as the Pacific railroad! Whatever may be the social development of the human race hereafter, and however wonderful the applications of art and science to the uses of life, will not our own age be looked back upon as perhaps the grandest in its history? To have lived in a period that saw the mysteries of Central Africa explained, the continents united with telegraphic nerves, the oceans traversed with steamships and monitors, the seas clasped together with railways, and, as we hope, the thin air made a navigable element, will be to have enjoyed the most startling triumphs of emotion of which the soul is capable.

What first strikes the attention upon comparing the rivers of the New and the Old World is the diminutive size of the latter, especially of many in the most civilized portions of Europe, or rendered famous in classical times. The Nile, with its ancient mysteries, its dim historic memorials of one of the oldest civilizations, its stupendous monuments of human wisdom and of human folly over which the centuries have brooded in solemn silence, and its wonderful physical peculiarities, is, indeed, a magnificent river. Reaching from the Mediterranean to the central regions of Africa, and forming an intimate connection with its great lake and river system,

it will doubtless accomplish for that portion of Africa what the Mississippi has done, and is now doing, in the material development of the United States -what the Danube may also accomplish in Eastern Europe, the Amazon in South America, and the Hoang Ho in Eastern Asia, when their expiring strata of civilizations shall have been aroused by the restless, aggressive spirit of modern times. The Jordan is only a mountain torrent. The Tiber and the Po can be swum with a single arm. The Simois and Scamander, the sacred rivers of Troy, are, like the Rubicon, the merest brooks, and would hardly drive a saw-mill. The Cephisus can be leaped across, and the Ilissus scarcely suf fices for a few Athenian washerwomen, sorry representatives of its nymphs and graces of old.

The Mississippi river drains not far from a million and a quarter square miles of territory, equal to about one third of the extent of Europe. From the source of the Missouri, on the eastern slope of the Rocky Mountains, to the Balize, is, following the windings of the river, a distance of four thousand five hundred miles. A circular line drawn through the head waters of the Mississippi and its chief tributaries would not be less than six thousand miles in length. With all of its confluents the Mississippi forms a great moving sinuous highway fully twenty-five thousand miles long, and ploughed by many thousand steamboats. They stretch out as if to embrace the beauty, to grasp the wealth, and gather, as into a lap, the products of the vast region between the two mountain chains of the continent; the coal and oil of the Alleghanies, the gold of the Rocky Mountains, the grain, lumber, and lead of the North, and the cotton, sugar, and tropical fruits of the South. Equally well will they serve for the distribution of the Asiatic commerce and travel which will be poured across the continent on the completion of the Pacific railroad. St. Louis may then become a great

distributing centre, and the same causes which have made London, Paris, Vienna, and Pekin the commercial capitals of their respective countries, may, in time, give that favored and opulent city the supremacy now enjoyed by the great marts of trade on the Atlantic coast. It is hardly safe to predict what may be the social and material, much less the intellectual possibilities of that near period, when, gliding on "the pale iron edge," we may jostle Chinese mandarins en route for Europe, and Eu. ropean money kings on their way to the Golcondas of the East.

The lotus-eating tourist of the Nile floats dreamily along the river between quaint villages and graceful palm-trees, past the pyramids, past the deserted sites of ancient cities, past the stupendous ruins of Luxor and Thebes. The monotony of the desert is broken by gloomy hills of sunburnt rock, and by the narrow strip of verdure which fringes both banks of the river. Should he push his explorations further, he will come in contact with the barbarous negro tribes of the upper Nile, and may encounter troops of giraffes and elephants.

How different the objects that attract the attention of the voyage up the Mississippi! The eye is charmed with the prospect of orange groves, of vast fields of sugar-cane of the deepest green, and of cotton plantations whose verdure and bloom at the proper season are only equalled in beauty by the snow-like whiteness of the opened balls. The forests are hung with long festoons of moss, giving them a sombre, funereal aspect. For between two and three hundred miles, both river banks, called coasts in Louisiana, are lined almost continuously with plantations, which, before the war, were in a high state of culti vation and furnished homes of luxury. The region now teeming with such active and varied life, inspired by the adjacent city of New Orleans, is made romantic by the adventures of De Soto and La Salle, and the wandering hi
