As soon as we passed Pital we entered the great forest, the black margin of which we had seen for many miles, that extends from this point to the Atlantic. At first the road lay through small trees and brushwood, a second growth that had sprung up where the original forest had been cut for maize plantations; but after passing a brook bordered by numerous plants of the pita, from which a fine fibre is obtained, and which gives its name to Pital, we entered the primeval forest. On each side of the road great trees towered up, carrying their crowns out of sight amongst a canopy of foliage; lianas wound round every trunk and hung from every bough, passing from tree to tree, and entangling the giants in a great network of coiling cables, as the serpents did Laocoon; the simile being strengthened by the fact that many of the trees are really strangled in the winding folds. Sometimes a tree appears covered with beautiful flowers, which do not belong to it, but to one of the lianas that twines through its branches and sends down great rope-like stems to the ground. Climbing ferns and vanilla cling to the trunks, and a thousand epiphytes perch themselves on the branches. Amongst these are large arums that send down aerial roots, tough and strong, and universally used instead of cordage by the natives. Amongst the undergrowth several small species of palms, varying in height from two to fifteen feet, are common; and now and then magnificent tree ferns, sending off their feathery crowns twenty feet from the ground, delight the sight with their graceful elegance. Great broad-leaved heliconiae, leathery melastomae, and succulent-stemmed, lop-sided-leaved begonias are abundant, and typical of tropical American forests. Not less so are the cecropia trees, with their white stems and large palmated leaves standing up like great candelabra. Sometimes the ground is carpeted with large flowers, yellow, pink, or white, that have fallen from some invisible tree-top above, or the air is filled with a delicious perfume, for the source of which one seeks around in vain, as the flowers that cause it are far overhead out of sight, lost in the great overshadowing crown of verdure. Numerous babbling brooks intersect the forest, with moss-covered stones and fern-clad nooks. One's thoughts are led away to the green dells in English denes, but are soon recalled; for the sparkling pools are the favourite haunts of the fairy humming-birds, and like an arrow one will dart up the brook, and, poised on wings moving with almost invisible velocity, clothed in purple, golden, or emerald glory, hang suspended in the air; gazing with startled look at the intruder, with a sudden jerk, turning round first one eye, then the other, and suddenly disappear like a flash of light.
