London: Tablet Publishing Company: 188, 189. <q>Rivalries of a commercial nature have necessarily existed between the British and French merchants on [the West African] coast, especially with reference to the trade in gum, which is very lucrative, yielding very commonly returns not much under cent per cent. [...] Ġum is, in fact, an article with which the chief manufacturers of England and france cannot well dispense. It is used in almost every process of dyeing, in the printing of cottons, in the fabrication of silks, ribbons, lawns, gauzes, cambrics, and hats. It is frequently an ingredient in medical and confectionary preparations; it enters into the composition of colours for painters; it is necessary to the varnisher and gilder, and a great variety of other artizans. It was formerly obtained only from Arabia, whence it was imported into France by the way of Marseilles, and through France to England and all Europe. The Dutch, however, in their intercourse with the African Moors, discovered that they had forests in the desert of Sahara which produced gum in abundance. [...] Upon examination, the Dutch found that the African gum was of a purer and more mucilaginous quality than even that of Arabia. Hence it soon became a most desirable article of commerce [...].</q></cite><span
