base of the perpendicular rocks higher up, where the spring appeared to issue, we proceeded there, and found, to our great joy, a little trickle of pure and delightfully cool water, and a shady place where we could rest and eat our lunch in comfort.
We then went on till we arrived where our guide said the cave was situated; but having been there only once he could not find it again, among the confused mass of rock which in several places appeared to present openings, but which on searching the spot deceived us. After various clamberings we gave up the search, and determined to return home and get a better guide another day.
On our way back we passed by a high cliff, on which were some of the picture-writings I had so much wished to see. They were executed in a red tint, produced apparently by rubbing them in with pieces of the rock, which in places is of that colour. They looked quite fresh, and were not at all obliterated by the weather, though no one knows their antiquity. They consisted of various figures, rudely executed, some representing animals, as the alligator and birds, others like some household utensils, and others again circles and mathematical figures, while there were some very complicated and fantastic forms: all were scattered irregularly over the rock to the height of eight or ten feet. The size of most of the figures was from one to two feet.
I took a general sketch of the whole, and some accurate tracings of the more curious single figures, which have unfortunately been since lost. The night felt chilly and damp, and we had nothing to cover ourselves with, or should have slept on the mountain. As it was, we arrived home very tired about eight o'clock, and were soon glad to turn into our hammocks.
'The next day Senhor Nunez determined to go with us himself to show us the cave and some more picture-writings, situated in another part of the mountain. We now went on horseback, but could no more find the cave than before, and were forced to send our Indian for an old man who lived a couple of miles off, and who knew the place well. While he was gone, Senhor Nunez went with me to find the picture-writings, which we did after a fatiguing walk. They were situated on a perpendicular rock, rising from the top of a steep, stony slope, which almost deterred me from getting up to them, as I was very tired and thirsty, and there was no water, How-
