Another effort has been made to attract commercial enterprise to this region by offering any mining company permission to search for the ores and work them. Such a company, however, would gain but little in the way of protection or aid from the government of Mozambique, as that can but barely maintain a hold on its own small possessions; the condition affixed of importing at the company's own cost a certain number of Portuguese from the island of Madeira or the Azores, in order to increase the Portuguese population in Africa, is impolitic. Taxes would also be levied on the minerals exported. It is noticeable that all the companies which have been proposed in Portugal have this put prominently in the preamble, "and for the abolition of the inhuman slave-trade." This shows either that the statesmen in Portugal are enlightened and philanthropic, or it may be meant as a trap for English capitalists; I incline to believe the former. If the Portuguese really wish to develop the resources of the rich country beyond their possessions, they ought to invite the co-operation of other nations on equal terms with themselves. Let the pathway into the interior be free to all; and, instead of wretched forts, with scarcely an acre of land around them which can be called their own, let real colonies be made. If, instead of military establishments, we had civil ones, and saw emigrants going out with their wives, plows, and seeds, rather than military convicts with bugles and kettle-drums, we might hope for a return of prosperity to Eastern Africa.
The village of Senna stands on the right bank of the Zambesi. There are many reedy islands in front of it, and there is much bush in the country adjacent. The soil is fertile, but the village, being in a state of ruin, and having several pools of stagnant water, is very unhealthy. The bottom rock is the akose of Brongniart, or granitic grit, and several conical hills of trap have burst through it. One standing about half a mile west of the village is called Baramuana, which has another behind it; hence the name, which means "carry a child on the back". It is 300 or 400 feet high, and on the top lie two dismounted cannon, which were used to frighten away the Landeens, who, in one attack upon Senna, killed 150 of the inhabitants. The prospect from Baramuana is very fine; below, on the eastward, lies the Zambesi, with the village of Senna; and some twenty or thirty miles beyond stands the lofty mountain Morumbala, probably 3000 or 4000 feet high. It is of an oblong shape, and from its physiognomy, which can be distinctly seen when the sun is in the west, is evidently igneous. On the northern end there is a hot sulphurous fountain, which my Portuguese friends refused to allow me to visit, because the mountain is well peopled, and the mountaineers are at present not friendly with the Portuguese. They have plenty of garden-ground and running water on its summit. My friends at Senna declined the responsibility of taking me into danger. To the north of Morumbala we have a fine view of the mountains of the Maganja; they here come close to the river, and terminate in Morumbala. Many of them are conical, and the Shire is reported to flow among them, and to run on the Senna side of Morumbala before joining the Zambesi. On seeing the confluence afterward, close to a low range of hills beyond Morumbala, I felt inclined to doubt the report, as the Shire must then flow parallel with the Zambesi, from which Morumbala seems distant only twenty or thirty miles. All around to the southeast the country is flat, and covered with forest, but near Senna a number of little abrupt conical hills diversify the scenery. To the west and north the country is also flat forest, which gives it a sombre appearance; but just in the haze of the horizon southwest by south, there rises a mountain range equal in height to Morumbala, and called Nyamonga. In a clear day another range beyond this may be seen, which is Gorongozo, once a station of the Jesuits. Gorongozo is famed for its clear cold waters and healthiness, and there are some inscriptions engraved on large square slabs on the top of the mountain, which have probably been the work of the fathers. As this lies in the direction of a district between Manica and Sofala, which has been conjectured to be the Ophir of King Solomon, the idea that first sprang up in my mind was, that these monuments might be more ancient than the Portuguese; but, on questioning some persons who had seen them, I found that they were in Roman characters, and did not deserve a journey of six days to see them.
