These Tubes Were Formed By Plastering A Mixture Of Clay And Grass Round A Smooth Roller Of Wood, Which, As Soon As The Clay Began To Harden, Was Withdrawn, And The Tube Left To Dry In The Sun.

The ironstone which I saw was very heavy, of a dull red colour with greyish specks; it was broken into pieces about the size of a hen's egg.

A bundle of dry wood was first put into the furnace, and covered with a considerable quantity of charcoal, which was brought, ready burnt, from the woods. Over this was laid a stratum of ironstone, and then another of charcoal, and so on, until the furnace was quite full. The fire was applied through one of the tubes, and blown for some time with bellows made of goats' skins. The operation went on very slowly at first, and it was some hours before the flame appeared above the furnace; but after this it burnt with great violence all the first night, and the people who attended put in at times more charcoal. On the day following the fire was not so fierce, and on the second night some of the tubes were withdrawn and the air allowed to have freer access to the furnace; but the heat was still very great, and a bluish flame rose some feet above the top of the furnace. On the third day from the commencement of the operation, all the tubes were taken out, the ends of many of them being vitrified with the heat; but the metal was not removed until some days afterwards, when the whole was perfectly cool. Part of the furnace was then taken down, and the iron appeared in the form of a large irregular mass, with pieces of charcoal adhering to it. It was sonorous; and when any portion was broken off, the fracture exhibited a granulated appearance, like broken steel. The owner informed me that many parts of this cake were useless, but still there was good iron enough to repay him for his trouble. This iron, or rather steel, is formed into various instruments by being repeatedly heated in a forge, the heat of which is urged by a pair of double bellows of a very simple construction, being made of two goats' skins the tubes from which unite before they enter the forge, and supply a constant and very regular blast. The hammer, forceps, and anvil are all very simple, and the workmanship (particularly in the formation of knives and spears) is not destitute of merit. The iron, indeed, is hard and brittle, and requires much labour before it can be made to answer the purpose.

Such is the chief information I obtained concerning the present state of arts and manufactures in those regions of Africa which I explored in my journey. I might add, though it is scarce worthy observation, that in Bambarra and Kaarta the natives make very beautiful baskets, hats, and other articles, both for use and ornament, from rushes, which they stain of different colours; and they contrive also to cover their calabashes with interwoven cane, dyed in the same manner.
