After the beads came the wire question. I discovered, after considerable trouble, that Nos. 5 and 6--almost of the thickness of telegraph wire--were considered the best numbers for trading purposes. While beads stand for copper coins in Africa, cloth measures for silver; wire is reckoned as gold in the countries beyond the Tan-ga-ni-ka.* Ten frasilah, or 350 lbs., of brass-wire, my Arab adviser thought, would be ample. * It will be seen that I differ from Capt. Burton in the spelling of this word, as I deem the letter "y" superfluous. Having purchased the cloth, the beads, and the wire, it was with no little pride that I surveyed the comely bales and packages lying piled up, row above row, in Capt. Webb's capacious store-room. Yet my work was not ended, it was but beginning; there were provisions, cooking-utensils, boats, rope, twine, tents, donkeys, saddles, bagging, canvas, tar, needles, tools, ammunition, guns, equipments, hatchets, medicines, bedding, presents for chiefs--in short, a thousand things not yet purchased. The ordeal of chaffering and haggling with steel-hearted Banyans, Hindis, Arabs, and half-castes was most trying. For instance, I purchased twenty-two donkeys at Zanzibar. $40 and $50 were asked, which I had to reduce to $15 or $20 by an infinite amount of argument worthy, I think, of a nobler cause. As was my experience with the ass-dealers so was it with the petty merchants; even a paper of pins was not purchased without a five per cent. reduction from the price demanded, involving, of course, a loss of much time and patience. After collecting the donkeys, I discovered there were no pack-saddles to be obtained in Zanzibar. Donkeys without pack-saddles were of no use whatever. I invented a saddle to be manufactured by myself and my white man Farquhar, wholly from canvas, rope, and cotton. Three or four frasilahs of cotton, and ten bolts of canvas were required for the saddles. A specimen saddle was made by myself in order to test its efficiency. A donkey was taken and saddled, and a load of 140 lbs. was fastened to it, and though the animal--a wild creature of Unyamwezi--struggled and reared frantic ally, not a particle gave way. After this experiment, Farquhar was set to work to manufacture twenty-one more after the same pattern. Woollen pads were also purchased to protect the animals from being galled. It ought to be mentioned here, perhaps, that the idea of such a saddle as I manufactured, was first derived from the Otago saddle, in use among the transport-trains of the English army in Abyssinia.
