Rivers constitute an important part of the aqueous portion of the globe; with the great lines of water, with streams and rivulets, they form a numerous family, of which lakes, springs, or the meltings of ice and snow, upon the summits of high mountain chains, are the parents. The Shannon has its source in a lake; the Rhone in a glacier; and the Abyssinian branch of the Nile in a confluence of fountains. The country where some of the mightiest rivers of the globe have their rise has not yet been sufficiently explored to render their true source ascertainable. The origin of others is doubtful, owing to a number of rills presenting equal claims to be considered as the river-head; but many are clearly referable to a single spring, the current of which is speedily swelled by tributary waters, ultimately flowing in broad and deep channels to the sea. Inglis, who wandered on foot through many lands, had a fancy, which he generally indulged, to visit the sources of rivers, when the chances of his journey threw him in their vicinity. Such a pilgrimage will often repay the traveler, by the scenes of picturesque and secluded beauty into which it leads him; and even when the primal fount is insignificant in itself, and the surrounding landscape exhibits the tamest features, there is a reward in the associations that are instantly wakened up--the thought of a humble and modest commencement issuing in a long and victorious career--of the tiny rill, proceeding, by gradual advances, to become an ample stream, fertilizing by its exudations and rolling on to meet the tides of the ocean, bearing the merchandise of cities upon its bosom. The Duddon, one of the most picturesque of the English rivers, oozes up through a bed of moss near the top of Wrynose Fell, a desolate solitude, yet remarkable for its huge masses of protruding crag, and the varied and vivid colors of the mosses watered by the stream. Petrarch’s letters and verses have given celebrity to the source of the Sorques--the spring of Vaucleuse, which bursts in an imposing manner out of a cavern, and forms at once a copious torrent. The Scamandar is one of the most remarkable rivers for the grandeur of its source--a yawning chasm in Mount Gargarus, shaded with enormous plane-trees, and surrounded with high cliffs from which the river impetuously dashes in all the greatness of the divine origin assigned to it by ancient fable. To discover the source of the Nile, hid from the knowledge of all antiquity, was the object of Bruce’s adventurous journey; and we can readily enter into his emotions, as he stood by the two fountains, after the toils and hazard he had braved. “It is easier to guess,” he remarks, “than to describe the situation of my mind at that moment--standing in that spot which had baffled the genius, industry, and inquiry of both ancients and moderns, for the course of three thousand years. Kings had attempted this discovery at
