confused, dipping in various directions about 12°, with volcanic masses rising up among them. As nearly as we could judge by the distances we had come, these rapids must be in about 4° of south latitude, where a considerable bend in the river occurs. Above are numerous falls and rapids, and after a time the forest ceases, and open undulating plains are found. From the point we reached, the country becomes very interesting, and we much regretted that we were unable to-explore it further.
On our return to Aroyas, our men, while descending the various smaller rapids, shouted and sang in the most wild and excited manner, and appeared to enjoy it amazingly. They had had a hard day's work, having paddled and poled about twenty miles against a powerful current, in some places so strong as to require all their exertions to keep the boat's head up the stream. At Aroyas we took some coffee, and then turned into our rédés in an open shed about twelve feet square, at the back part of the house, where six or eight other members of the family also found room for themselves. We were kept awake some time by our pilot, who had got drunk on caxaça, and was very violent and abusive, so to quict him we administered another glass or two, which soon had the desired sedative effect. The next morning he looked very dull and sheepish; in fact, most of the Tapuyas, or half-civilised Indians, consider it disgraceful to get drunk, and seem ashamed afterwards.
After paying our hostess in biscuit, tea, and sugar, which were great luxuries to her, we started on our return to the canoe, which we reached about noon, having stayed an hour to explore the igaripé for gold, but without the smallest success. At the cano we found that Isidora had some turtle stew ready, to which we did ample justice, and, finding the man we had left with him very ill, went on immediately to Jucahipuah, where he could have some "remedios" given him by the women. We found there a canoe going to Baiāo, and sent him by it, as he would thus get home sooner than if he remained with us.
While walking on the beach I saw a tall, narrow-leaved, white-flowered Polygonum, so like some of our British species as to call up thoughts of home and of my botanical rambles there. Many curious land-shells were found, but all dead and
