Our journey across that blooming wilderness will never fade from my recollection, but when I attempt to give the reader an idea of it, impressions crowd so thick and fast upon me as to choke my utterance; I am equally in danger of soaring into a wild extravagance of generality and sinking into a mere catalogue of detail. Yet I find it impossible to hit a mean that can do any justice to it. The extraordinary way in which the ancient lavas of the interior had been riven, upheaved, and piled upon each other by the volcanic forces, the bewildering variety and exuberance of the tropical plants and trees which battened on the rich and crumbling soil, completely baffles all description. What the imagination is unable to conceive, and the eye itself is overpowered in beholding, the pen can never hope to depict. Let the grandest mountain scenes of your memory be jumbled together as in a dream and overgrown with the maddest jungles of the Ganges or the Amazon, and the phantasmagoria would still be nothing to the living reality. Most of the highest peaks and ridges, as well as the deepest valleys and ravines, were covered with the embowering forest; but here and there a huge boss of granite or porphyry reared its bare scalp out of the verdure like the head and shoulders of some antediluvian monster. The gigantic palms and foliage trees, all tufted with air-plants or strangled with climbers, were literally buried in flowers of every hue, and the crown of the forest rolled under us like a sea of blossoms. Every moment one enchanting prospect after another opened to our wondering eyes. Now it was a waterfall, gleaming like a vein of silver on the brow of a lofty precipice, and descending into a lakelet bordered with red, blue, and yellow lilies. Again it was a natural bridge, spanning a deep chasm or tunnel in the rock, through which a river boiled and roared in a series of cascades and rapids. Ever and anon we passed over glades and prairies, carpeted with orchids, and dotted with clumps of shrubbery, a mass of golden bloom, or tremendous blocks of basalt hung with crimson creepers. Butterflies with azure wings of a surprising spread and lustre, alighted on the flowers, and great birds of resplendent plumage flashed from grove to grove. A sun, twice the diameter of ours, blazed in the northern sky, but the intensity of his rays was tempered by a thin veil of cloud. The atmosphere although warm and moist, was not oppressive like that of a forcing-house, and the breeze was balmy with delicious perfume. As each new marvel came in sight, unstaled by familiar and untarnished by vulgar associations, fresh from the hand of nature, so to speak, we were filled as we had never been before with an intoxicating sense of the divine mystery and miracle of life. For myself I was fairly dumbfounded with amazement, and my companion, the hard-headed sceptical astronomer, kept on crying and muttering to himself, "My God! my God!" as if he had become a drivelling fool.
