human figures, as well as circles, squares, and other regular forms. They are all. scraped on the excessively hard granitic rock. Some are entirely above and others below high-water mark, and many are quite covered with a growth of lichens, through which, however, they are still plainly visible. (Plates XV. and XVI.) Whether they had any signification to those who executed them, or were merely the first attempts of a rude art guided only by fancy, it is impossible now to say. It is, however, beyond a doubt that they are of some antiquity, and are never executed by the present race of Indians. Even among the most uncivilised tribes, where these figures are found, they have no idea whatever of their origin; and if asked, will say they do not know, or that they suppose the spirits did them. Many of the Portuguese and Brazilian traders will insist upon it that they are natural productions, or, to use their own expression, that " God made them ; " and on any objection being made they triumphantly ask, "And could not God make them?" which of course settles the point. Most of them in fact are quite unable to see any difference between these figures and the natural marks and veins that frequently occur in the rocks.
