When a company of these carriers, or our own party, arrives at one of these sleeping-places, immediate possession is taken of the sheds. Those who come late, and find all occupied, must then erect others for themselves; but this is not difficult, for there is no lack of long grass. No sooner do any strangers appear at the spot, than the women may be seen emerging from their villages bearing baskets of manioc-meal, roots, ground-nuts, yams, bird's-eye pepper, and garlic for sale. Calico, of which we had brought some from Cassange, is the chief medium of exchange. We found them all civil, and it was evident, from the amount of talking and laughing in bargaining, that the ladies enjoyed their occupation. They must cultivate largely, in order to be able to supply the constant succession of strangers. Those, however, near to the great line of road, purchase also much of the food from the more distant villages for the sake of gain.
Pitsane and another of the men had violent attacks of fever, and it was no wonder, for the dampness and evaporation from the ground was excessive. When at any time I attempted to get an observation of a star, if the trough of mercury were placed on the ground, so much moisture was condensed on the inside of the glass roof over it that it was with difficulty the reflection of the star could be seen. When the trough was placed on a box to prevent the moisture entering from below, so much dew was deposited on the outside of the roof that it was soon necessary, for the sake of distinct vision, to wipe the glass. This would not have been of great consequence, but a short exposure to this dew was so sure to bring on a fresh fever, that I was obliged to give up observations by night altogether. The inside of the only covering I now had was not much better, but under the blanket one is not so liable to the chill which the dew produces.
It would have afforded me pleasure to have cultivated a more intimate acquaintance with the inhabitants of this part of the country, but the vertigo produced by frequent fevers made it as much as I could do to stick on the ox and crawl along in misery. In crossing the Lombe, my ox Sinbad, in the indulgence of his propensity to strike out a new path for himself, plunged overhead into a deep hole, and so soused me that I was obliged to move on to dry my clothing, without calling on the Europeans who live on the bank. This I regretted, for all the Portuguese were very kind, and, like the Boers placed in similar circumstances, feel it a slight to be passed without a word of salutation. But we went on to a spot where orange-trees had been planted by the natives themselves, and where abundance of that refreshing fruit was exposed for sale.
On entering the district of Ambaca, we found the landscape enlivened by the appearance of lofty mountains in the distance, the grass comparatively short, and the whole country at this time looking gay and verdant. On our left we saw certain rocks of the same nature with those of Pungo Andongo, and which closely resemble the Stonehenge group on Salisbury Plain, only the stone pillars here are of gigantic size. This region is all wonderfully fertile, famed for raising cattle, and all kinds of agricultural produce, at a cheap rate. The soil contains sufficient ferruginous matter, to impart a red tinge to nearly the whole of it. It is supplied with a great number of little flowing streams which unite in the Lucalla. This river drains Ambaca, then falls into the Coanza to the southwest at Massangano. We crossed the Lucalla by means of a large canoe kept there by a man who farms the ferry from the government, and charges about a penny per head. A few miles beyond the Lucalla we came to the village of Ambaca, an important place in former times, but now a mere paltry village, beautifully situated on a little elevation in a plain surrounded on all hands by lofty mountains. It has a jail, and a good house for the commandant, but neither fort nor church, though the ruins of a place of worship are still standing.
