Some of the campos we passed through were covered with a large species of tree-lily, bearing a profusion of beautiful purple flowers. Early in the afternoon we continued our journey, and halted for the night in a wooded campo, a little above a large Buriti swamp, sleeping on a hard bed, there being no place wherein to sling our hammocks, and suffering much from the cold. Although accustomed daily both to privations and fatigue, there was an indescribable pleasure in the wild life we had long been leading; it is true we were deprived of nearly all the comforts of civilized life, but we were at the same time free from all its restraints. When we rose in the morning we knew not where our next sleeping place might be, but the choice was almost always at our command, which however was not made at random, but constantly regulated by some indispensable requisites, such as water and grass for the horses, trees from which to suspend our hammocks, and wood wherewith to make our nightly fire. We had hitherto met with but little difficulty in finding, all these together; but the part of the Serra Geral on which we were now travelling called the Serra das Araras, was in most places so destitute of arboreous vegetation, that trees were seldom met with in combination with other requisites for an encampment. On arriving at a place where we wished to remain, each person had his own department to attend to. The first thing was to unload the horses, at which all assisted. Mr. Walker and I always saddled and unsaddled our own animals: two of the men then took them to the spot that offered the best pasture, where they were left after fastening their fore legs together with leathern straps to prevent them from straying during the night; these men on their return brought with them as much dry wood as they could carry. Another man was despatched with a large leather bag to fetch water; while Mr. Walker and I arranged the packages together in such a manner that they could readily be covered over with skins in the event of rain; two large trunks put together served as our table, while two smaller ones supplied us with seats. Generally before the men returned, Mr. Walker had kindled a fire, and while supper was preparing, which was also our dinner, for we took only two meals a day, I occupied myself in preparing and changing the specimens collected on the previous days. By the time the water was boiled for our tea, the piece of dried beef which had been put on a wooden spit, and suspended over the hot embers, was ready for our supper, as it required to be little more than heated. The tea, dried beef, and farinha de mandiocca constituted our usual fare; and I am certain that if any of our European friends, who had never seen this kind of provision, could have been suddenly transported to one of our meals, he would have concluded, from the appearance of our food, that we were eating saw-dust and roasted leather. Our greatest comfort was a
