On the 1st of July, preparatory to our departure, my horses were brought over from the island to the east side of the San Francisco, and early on the following morning the luggage was all at once passed over, in a large ajojo, two canoes lashed together. All being now prepared, I had resolved to proceed immediately, but on collecting the animals, my own saddle horse was not to be found; all that day was spent in search of it, but the only trace left, was the leathern strap, by which its fore legs had been secured, and which was found in the wood unbuttoned at both ends, and as this could only have been done by some person, we came to the conclusion that the horse was stolen; I, therefore, resolved to lose no more time in looking after it. About midnight we were awakened by a black man, who had assisted my men in the morning’s search, who came to inform me that a horse similar to mine, had been seen during the day, tied to a tree in the wood considerably further up the river. Early next morning, I despatched one of my people in that direction to look for it, who returned in about an hour, bringing the horse with him; it was evident it had been taken there, in the hope of its remaining concealed, until an opportunity occurred of carrying it away altogether. I now lost no time in commencing the journey, and making a short stage of about a league, rested, during the middle of the day, at a fazenda called Guaribas. The first half league was through a flat thinly-wooded tract, which is generally overflowed by the river, during the rainy season; I saw some fine large trees in this wood, of a species of _Triplaris_, and an arboreous _Bignonia_, destitute of leaves, but covered with flowers not unlike those of the Foxglove, in shape, size, and colour. The underwood here consisted chiefly of different kinds of _Mimosa_, _Acacia_, _Bauhinia_, _Cæsalpinia_, &c., and an immense number of Lemon trees, loaded with fruit; this tree has here become quite naturalized, and the cattle that pasture in the woods are so fond of the fallen fruit, that when killed, their flesh smells strongly of it. The other half league led through a thickly-wooded Taboleira. At Guaribas, I occupied myself with skinning a very large howling monkey, which Mr. Walker shot the evening before, on a tree on the banks of the Rio de San Francisco; and in the afternoon we advanced another two leagues, and arrived at a fazenda, called Passagem. The road was dreadfully bad, in consequence of the underwood which choaked the almost untrodden path; on this journey, every little twig and blade of grass was loaded with carrapatos, in balls, often the size of filberts, and we became completely covered with these annoying insects; the banks of the little stream near the house, in particular, were swarming with them. In the afternoon, we passed two small lakes which were full of wild ducks, but we were too much annoyed by the badness of the road to lose time in shooting any of them, although
