The next day we reached the Paramo, on the summit of the Cordilleras, thirteen thousand feet above the level of the sea. We caught sight of numbers of wild asses, which inhabit this mountainous region. The hoof of the animal is divided like that of a pig. They are very shy, so that even the Indians are seldom able to approach near enough to kill them; and they are also very swift of foot. We crossed the Paramo in safety, and continued our journey for several days without any further adventure. The views, as we descended the mountains, were magnificent. We could see the Cordilleras on the opposite side of the plain of Bogota, seventy or eighty miles off; while north and south rose prodigious heights, with apparently perpendicular sides, their bases covered with thick, gloomy forests, which appeared perfectly impenetrable. As we looked back, it seemed impossible that we should have crossed the range. Frequently we passed through dark gorges piercing the forests, two miles in length, and not more than three or four feet wide, the vegetation on either side being most luxuriant. We had to be on our guard against bruising our legs by pieces of rock; or getting our clothes torn by the long thorns of the bamboos; or being knocked off our mules--for we had again mounted--by the branches of trees. We met a party of peons conveying salt on the backs of oxen to Cartage. The cargoes were small, and placed in such a manner as to enable the animals to pass through these narrow places. Fortunately there was an opening near the spot, or we should have been unable to pass each other. At last we reached a tambo, or shed, built for the use of travellers-- the first sign of civilisation we had met since we left the western side of the Cordilleras. We were now once more in a warmer region. Butterflies of large size, covered with orange-coloured spots, fluttered about; and red monkeys leapt from tree to tree, frequently coming down to make grimaces at us. Another day's journey brought us to a cottage inhabited by peasants, who gave us a satisfactory welcome. At length we reached the place where we were to part from our silleros and peons, and continue our journey on horseback. "I hope that we shall meet again," I said to Manoel, who had won my regard. "We shall, senor, it may be, if you do not soon leave the country," replied Manoel, looking earnestly at me. "I may stay longer than I at first intended," I said. Manoel and the rest of our attendants were well satisfied with the payment we had made them. Mr Laffan and I, with Domingo, now continued our journey on horseback, the roads being tolerable. But, eager as we were to reach Bogota, we agreed that it would be wise, the better to keep up our assumed character, to visit the waterfall of Tequendama, which was not far out of our direct road. It is formed by the river Bogota, which is hereabouts sixty yards in breadth.
