Article IV. 



Of Commerce and Navigation. 



Like that of other countries, the commerce of the Captaincy 

 of the Rios de Senna, consists of two kinds, exterior and 

 interior; but since in this district the internal is so inti- 

 mately connected with the external, and is indeed the source 

 of it, and as all the exports are made from the port of Quilli- 

 mane, I shall not divide the subject, but consider both kinds 

 of traffic under one head. Agricultural produce, as I have 

 before noticed, constitutes but a very small portion of the 

 exports, instead of forming as it should, their principal and 

 most interesting feature. Gold, ivory, and slaves, are the 

 essential articles of commerce in the Ulterior, and even in 

 the lands of the Captaincy. The exports are gold, ivory, 

 slaves, copper, rice, wheat, oil, tobacco, teeth of the Hippo- 

 potami, Rhinoceros horns, wax, amber, pease, beans, maize, 

 and millet, onions and garlick. The imports are coarse 

 cotton stuffs from Asia, (for interior traffic,) fine cloths of 

 cotton, woollen, and silk ; beads, milk stones, (a large white 

 bead,) false coral, metal beads, coir, pewter, gunpowder, 

 arms, earthenware of all kinds, brandy, wine and other 

 liquors, sugar, soap, salt meat, butter, oil, pitch, salt fish, 

 (azectorias,) olives, tea, coffee, chocolate, spices, bristles of 

 all sorts, iron in bars, &c. &c. The greater proportion of 

 these imported articles, are sent into the interior to barter 

 for slaes, gold, and ivory; the remainder is consumed in the 

 Captaincy. Many of the things before-mentioned serve as 

 money, or media of exchange, such are the coarse stuffs, the 

 valorio, £a kind of bead,) beads, and pewter. The exporta- 

 tion from Quillimane between the 1st Jannary and 31st 

 December, 1806, were gold dust, 6780 maticalls ; in the 

 country these would be called sixty-seven partas and eighty 

 maticalls, — each anaticall is said to be equal to ten cruzadoes ; 

 therefore each parta is a thousand cruzadoes of imaginary 

 money: but the gold is valued by. its yveight, each parta 

 weighs nineteen ounces and a half. This gold has commonly 

 a cambio of 25 or 30 per cent, and often much more it 

 Mozambique and the Asiatic ports.*
