The country over which we passed before reaching this place, is of an undulating character, consisting generally of large open campos, the soil of which is principally a white sand, and being but scantily covered with herbaceous vegetation, the glare caused by the bright sun-shine was very fatiguing to the eyes. On these campos, as well as on the Chapada da Mangabeira, a dwarf cashew is very abundant, growing gregariously, and not more than a foot high; I found it both in flower and in fruit, but the latter is not much larger than a gooseberry. It seems to be distinct from the arboreous species, and is called by the Brazilians Cajú rasteiro. Although the hilly parts of the country are dry, and have an arid look, the little hollows or valleys which intersect them, have always a small stream of clear and cool water flowing through them, and are generally well wooded. About half a mile from the Aldea of Duro, we overtook an Indian who was returning from the woods, and who conducted us to the house of one of their two captains, of whom we made enquiries about a house to put up in, but he knew of none. After some time, we were permitted to occupy one not yet finished, being open all round, but well roofed; by means of some hides, we, however, contrived to render it somewhat comfortable. As I found it necessary to remain here for several days, I was well pleased to have the use of this habitation, as it was not safe to trust ourselves in the open air, now that the rains were setting in.
