Next morning after travelling three leagues and a half through a rather level and tolerably well-wooded country, we arrived towards mid-day at a place consisting of three houses called Campos; the tree most abundant on the road was the Imbuzeira, the fruit of which, called Imbú, was observed in such great plenty that the ground beneath them was completely yellow; we ate abundantly of it, and found it very grateful. About a league from Campos the country abounds with an arboreous species of _Jatropha_, with small white flowers, and sinuate leaves not unlike those of the holly, only larger; the footstalks of the leaves are furnished with a few long pointed prickles, and without being aware of their nature, I laid hold of a branch to collect a few specimens, but had no sooner done so than my whole hand felt as if it had been dipped into boiling oil, caused by the venom of the prickles which in many places had punctured the skin, and it was intolerably painful for several hours; on my next attempt I was more cautious, and succeeded in obtaining a few specimens. This plant is called by the inhabitants Favella, and in the dry season they scrape down the bark and the wood, which they put into the pools where the large pigeons and other birds resort; after having drunk of this poisoned water they either die or become very much stupified, and in this state are taken and eaten by the people. On this journey we saw a great many Maccaws (_Araras_) but they would not allow me to come within shot of them.
