The knives on [Plate V.] were obtained from natives composing these caravans.

From all the more intelligent natives I always obtained the same information respecting the origin of the ivory brought down to the coast, namely, that it was all from animals killed, and not from elephants found dead. The natives from the interior always laughed at the idea of ivory becoming scarce from the numbers of elephants that must necessarily be killed to supply the large number of tusks annually brought down,—the number slaughtered must therefore be very small in comparison to the living herds they must be in the habit of seeing on the vast plains of the interior. They are said to be shot, and that the natives put such a charge of powder and iron bullets into their guns that when fired from the shoulder the hunter cannot use his gun again that day, so great is the kick he gets from its recoil. I can well understand that this is not an exaggerated account, from the manner in which blacks always load a gun, the charge of powder being one handful, as much as it can hold, then a wadding of baobab fibre, then lead shot, or lead or iron bullets (in default of which they use the heavy round pieces of pisolitic iron ore very common in the country), another wad of baobab fibre, and the gun must then show that it is loaded a “palm,” or about eight or nine inches of the barrel.

On festive occasions, or at their burials, the guns are loaded with a tamping of “fuba,” or fine mandioca-meal, instead of other wadding, and they then give a terrific report when fired off, and not unfrequently burst.

This coast abounds with fish, but very few of the natives engage in their capture, as they make so much by trading that they will not take the trouble. Several fish, such as the “Pungo,” weighing as much as three “arrobas,” or ninety-six pounds, visit the coast only in the “cacimbo” or cold season of the year, or from June to August.

The Bay of Musserra is a noted place for large captures of this fine fish, as many as forty or fifty being caught in a day by the natives, with hook and line, from their small curious shaped canoes. It is a very firm-fleshed fish, and cut up, salted, and dried in the sun, was a great article of trade at Musserra, being sold to the natives from the interior, particularly to the “Zombos” composing the caravans of ivory, who are very fond of salt fish. There was a great row in the season 1870, which was a very scarce one for ground-nuts, between the natives of the interior and the blacks at Musserra, on account of the latter taking to collect Adansonia fibre in preference to catching “Pungo,” and therefore disappointing the inlanders of their favourite salt delicacy.

The canoes on this part of the coast, and as far north as Cabinda, are very curious, and totally unlike any that I have seen anywhere else. They are composed of two rounded canoes lashed or sewn together below, and open at the top. This aperture is narrow, and each canoe forms, as it were, a long pocket. The natives stand or sit on them with their legs in the canoe, or astride, as most convenient according to the state of the surf, on which these canoes ride beautifully.

The town of Musserra was formerly a large and populous one, but small-pox and “sleep disease” have reduced it to a mere handful.

This “sleep disease” was unknown south of the River Congo, where it formerly attacked the slaves collected in the barracoons for shipment. It suddenly appeared at the town of Musserra alone, where, I was told by the natives, as many as 200 of the inhabitants died of it in a few months. This was in 1870, and, curious to say, it did not spread to the neighbouring towns. I induced the natives to remove from the old town, and the mortality decreased till the disease died out.

This singular disease appears to be well known at Gaboon, &c., and is said to be an affection of the cerebellum. The subjects attacked by it suffer no pain whatever, but fall into a continual heavy drowsiness or sleep, having to be awakened to be fed, and at last become unable to eat at all, or stand, and die fast asleep as it were. There is no cure known for it, and the patients are said to die generally in about twenty to forty days after being first attacked.

There was nothing in the old town to account for this sudden and singular epidemic; it was beautifully clean, and well built on high, dry ground, surrounded by mandioca plantations, and the last place to all appearance to expect such a curious outbreak.
