In the afternoon we advanced as usual, and passed some deserted cottages, but towards the close of the day arrived at some that were inhabited, and at dusk put up near to two or three that stood together, after having crossed the Seara-Meirim for the last and forty-second time. This river takes its sources from the mountains to the northward, in the same direction as those of the river Açu, of which I shall have occasion to speak. The Seara-Meirim falls into the Potengi, and perhaps some branches of it bend their course as far as the Paraiba. The face of the country presents one continued flat, from Pai Paulo to the place at which we left the river; the soil is a loose sand, which is sometimes, though rarely, intermixed with black earth. The trees are thinly scattered, and, at the time that I travelled, were without leaves. The river winds like the coils of a serpent, to have followed them would have been endless; it sometimes fills after heavy rain, in the course of a very short time, the water coming down in a torrent, delayed only by the inequality of the depth of the channel, and the walls with which the rocks in some parts oppose its progress. The sand in the bed of the river is little different from that of which the banks are composed, being however on the whole thicker, and approaching nearer to gravel. The water which oozes from it, on digging into the sand, is in all parts brackish, and in some places is too salt for any use to be made of it. This is not, however, peculiar to the Seara-Meirim, for I found that all the beds of the rivers which become dry in the summer contained more or less salt; at best, the water taken from them was never quite sweet. The place at which we had arrived is reckoned to be distant forty leagues from Natal; the league of the Sertam is never less than four miles, and is often much more; there are _legoas grandes_, _legoas pequenas_, and _legoas de nada_, or nothing leagues, which I have found quite long enough, notwithstanding their encouraging name. Pai Paulo may be about eight or ten leagues from Natal, which makes the _travesia_ or barren-crossing, thirty or thirty-two leagues. We advanced at about three miles within the hour or rather more, and travelled from half-past five to ten in the morning, and in the afternoon from two, or half-past two, to six o’clock. We had now reached again the habitations of man; there was still the same burnt-up appearance, but the wells were taken care of, the water was better, and grass, although it was dry, was still to be had. I intended to accompany the Major, part of the way to his home, or the whole, but it was necessary that I should be guided by circumstances,—by the accounts we heard of the state of the country;—we advanced in our usual manner, resting more at mid-day, traversing a dead flat, and passing two or three _Fazendas_, or cattle estates, each day, of which the live stock was looking very miserable, and the people half starved.
