Being anxious to obtain some more knowledge of this interesting country and its ancient missionary establishments than the line of route by which we had come afforded, I resolved to visit the town of Massangano, which is situated to the south of Golungo Alto, and at the confluence of the rivers Lucalla and Coanza. This led me to pass through the district of Cazengo, which is rather famous for the abundance and excellence of its coffee. Extensive coffee plantations were found to exist on the sides of the several lofty mountains that compose this district. They were not planted by the Portuguese. The Jesuit and other missionaries are known to have brought some of the fine old Mocha seed, and these have propagated themselves far and wide; hence the excellence of the Angola coffee. Some have asserted that, as new plantations were constantly discovered even during the period of our visit, the coffee-tree was indigenous; but the fact that pine-apples, bananas, yams, orange-trees, custard apple-trees, pitangas, guavas, and other South American trees, were found by me in the same localities with the recently-discovered coffee, would seem to indicate that all foreign trees must have been introduced by the same agency. It is known that the Jesuits also introduced many other trees for the sake of their timber alone. Numbers of these have spread over the country, some have probably died out, and others failed to spread, like a lonely specimen which stands in what was the Botanic Garden of Loanda, and, though most useful in yielding a substitute for frankincense, is the only one of the kind in Africa.

A circumstance which would facilitate the extensive propagation of the coffee on the proper clay soil is this: The seed, when buried beneath the soil, generally dies, while that which is sown broadcast, with no covering except the shade of the trees, vegetates readily. The agent in sowing in this case is a bird, which eats the outer rind, and throws the kernel on the ground. This plant can not bear the direct rays of the sun; consequently, when a number of the trees are discovered in the forest, all that is necessary is to clear away the brushwood, and leave as many of the tall forest-trees as will afford good shade to the coffee-plants below. The fortunate discoverer has then a flourishing coffee plantation.

This district, small though it be, having only a population of 13,822, of whom ten only are white, nevertheless yields an annual tribute to the government of thirteen hundred cotton cloths, each 5 feet by 18 or 20 inches, of their own growth and manufacture.

Accompanied by the commandant of Cazengo, who was well acquainted with this part of the country, I proceeded in a canoe down the River Lucalla to Massangano. This river is about 85 yards wide, and navigable for canoes from its confluence with the Coanza to about six miles above the point where it receives the Luinha. Near this latter point stand the strong, massive ruins of an iron foundry, erected in the times (1768) and by the order of the famous Marquis of Pombal. The whole of the buildings were constructed of stone, cemented with oil and lime. The dam for water-power was made of the same materials, and 27 feet high. This had been broken through by a flood, and solid blocks, many yards in length, were carried down the stream, affording an instructive example of the transporting power of water. There was nothing in the appearance of the place to indicate unhealthiness; but eight Spanish and Swedish workmen, being brought hither for the purpose of instructing the natives in the art of smelting iron, soon fell victims to disease and "irregularities". The effort of the marquis to improve the mode of manufacturing iron was thus rendered abortive. Labor and subsistence are, however, so very cheap that almost any amount of work can be executed, at a cost that renders expensive establishments unnecessary.

A party of native miners and smiths is still kept in the employment of the government, who, working the rich black magnetic iron ore, produce for the government from 480 to 500 bars of good malleable iron every month. They are supported by the appropriation of a few thousands of a small fresh-water fish, called "Cacusu", a portion of the tax levied upon the fishermen of the Coanza. This fish is so much relished in the country that those who do not wish to eat them can easily convert them into money. The commandant of the district of Massangano, for instance, has a right to a dish of three hundred every morning, as part of his salary. Shell-fish are also found in the Coanza, and the "Peixemulher", or woman-fish of the Portuguese, which is probably a Manatee.

The banks of the Lucalla are very pretty, well planted with orange-trees, bananas, and the palm ('Elaeis Guineensis') which yields the oil of commerce. Large plantations of maize, manioc, and tobacco are seen along both banks, which are enlivened by the frequent appearance of native houses imbosomed in dense shady groves, with little boys and girls playing about them. The banks are steep, the water having cut out its bed in dark red alluvial soil. Before every cottage a small stage is erected, to which the inhabitants may descend to draw water without danger from the alligators. Some have a little palisade made in the water for safety from these reptiles, and others use the shell of the fruit of the baobab-tree attached to a pole about ten feet long, with which, while standing on the high bank, they may draw water without fear of accident.

Many climbing plants run up the lofty silk, cotton, and baobab trees, and hang their beautiful flowers in gay festoons on the branches. As we approach Massangano, the land on both banks of the Lucalla becomes very level, and large portions are left marshy after the annual floods; but all is very fertile. As an illustration of the strength of the soil, I may state that we saw tobacco-plants in gardens near the confluence eight feet high, and each plant had thirty-six leaves, which were eighteen inches long by six or eight inches broad. But it is not a pastoral district. In our descent we observed the tsetse, and consequently the people had no domestic animals save goats.

We found the town of Massangano on a tongue of rather high land, formed by the left bank of the Lucalla and right bank of the Coanza, and received true Portuguese hospitality from Senhor Lubata. The town has more than a thousand inhabitants; the district has 28,063, with only 315 slaves. It stands on a mound of calcareous tufa, containing great numbers of fossil shells, the most recent of which resemble those found in the marly tufa close to the coast. The fort stands on the south side of the town, on a high perpendicular bank overhanging the Coanza. This river is here a noble stream, about a hundred and fifty yards wide, admitting navigation in large canoes from the bar at its mouth to Cambambe, some thirty miles above this town. There, a fine waterfall hinders farther ascent. Ten or twelve large canoes laden with country produce pass Massangano every day. Four galleons were constructed here as long ago as 1650, which must have been of good size, for they crossed the ocean to Rio Janeiro.

Massangano district is well adapted for sugar and rice, while Cambambe is a very superior field for cotton; but the bar at the mouth of the Coanza would prevent the approach of a steamer into this desirable region, though a small one could ply on it with ease when once in. It is probable that the objects of those who attempted to make a canal from Calumbo to Loanda were not merely to supply that city with fresh water, but to afford facilities for transportation. The remains of the canal show it to have been made on a scale suited for the Coanza canoes. The Portuguese began another on a smaller scale in 1811, and, after three years' labor, had finished only 6000 yards. Nothing great or useful will ever be effected here so long as men come merely to get rich, and then return to Portugal.

The latitude of the town and fort of Massangano is 9d 37' 46" S., being nearly the same as that of Cassange. The country between Loanda and this point being comparatively flat, a railroad might be constructed at small expense. The level country is prolonged along the north bank of the Coanza to the edge of the Cassange basin, and a railway carried thither would be convenient for the transport of the products of the rich districts of Cassange, Pungo Andongo, Ambaca, Cambambe, Golungo Alto, Cazengo, Muchima, and Calumbo; in a word, the whole of Angola and independent tribes adjacent to this kingdom.
