The price of the articles brought to this market from the region of the Upper Niger, especially from Sansándi, varies greatly, depending as it does upon the supply of the moment. Provisions, during my stay, were, generally speaking, very cheap, while Caillié complains of the high prices which prevailed in his time.[20] But it must also be taken into account that the French traveller proceeded from those very countries on the Upper Niger from which Timbúktu is supplied, and where, in consequence, provisions are infinitely cheaper, while I came from countries which, owing to the state of insecurity and warfare into which they have been plunged for a long series of years, were suffering from dearth and famine. The chief produce brought to the market of Timbúktu consists of rice and negro corn; but I am quite unable to state the quantities imported. Besides these articles, one of the chief products is vegetable butter, or mai-kadéña, which, besides being employed for lighting the dwellings, is used most extensively in cookery as a substitute for animal butter, at least by the poorer class of the inhabitants. Smaller articles, such as pepper, ginger, which is consumed in very great quantities, and sundry other articles, are imported. A small quantity of cotton is also brought into the market, not from Sansándi, I think, but rather from Jimbálla and some of the neighbouring provinces, no cotton being cultivated in the neighbourhood of the town: but the natives do not seem to practise much weaving at home, even for their own private use. At the time of my visit, the caravan trade with Morocco, which is by far the most important, was almost interrupted by the feuds raging among the tribes along that road, especially between the Érgebát and Tájakánt on the one side, and the various sections of the Tájakánt on the other. This is the reason why in that year there were no large caravans at all, which in general arrive about the beginning of November, and leave in December or January. These caravans from the north are designated, by the Arabs in this region, by the curious name ʿakabár (in the plural, ʿakwabír); the origin of which I have not been able to make out, but it is evidently to be ranked among that class of hybrid words used by the people hereabouts, which belong neither to the Arabic nor to the Berber language. The same term is even used in Morocco to denote a very large caravan or an aggregate of many small caravans; but in Timbúktu the term kafla is quite unusual for small parties, the name in use being “réfega.” In former times these caravans, at least those from Morocco by way of Téfilélet, and from the wádí Darʿa by way of the territory of the ʿAríb, seem to have been numerous, although they never amounted to the number mentioned in Mr. Jackson’s account of Morocco[21], and in various other works.
