chasm which intervened between them and the city. It was, as has been remarked, of no great width, and the army drawn up on its borders was directly exposed to the archery of the garrison, on whom its own fire made little impression, protected as they were by their defences.
The general, annoyed by his position, sent a detachment to seek a passage lower down, by which the troops might be landed on the other side. But, although the banks of the ravine became less formidable as they descended, they found no means of crossing the river, till a path unexpectedly presented itself, on which, probably, no one before had ever been daring enough to venture.
From the cliffs on the opposite sides of the barranca, two huge trees shot up to an enormous height, and, inclining towards each other, interlaced their boughs so as to form a sort of natural bridge. Across this avenue, in mid-air, a Tlascalan conceived it would not be difficult to pass to the opposite bank. The bold mountaineer succeeded in the attempt, and was soon followed by several others of his countrymen, trained to feats of agility and strength among their native hills. The Spaniards imitated their example. It was a perilous effort for an armed man to make his way over this aerial causeway, swayed to and fro by the wind, where the brain might become giddy, and where a single false movement of hand or foot would plunge him in the abyss below. Three of the soldiers lost their hold and fell. The rest, consisting of some twenty or thirty Spaniards and a considerable number of Tlascalans, alighted in safety on the other bank.7 There hastily forming, they marched with all speed on the city.
