With a few exceptions they are all manufactured in Venice.

The greatest care must be exercised, or the traveller--ignorant of the prevailing fashion in the country he is about to explore--finds himself with an accumulation of beads of no more value than tokens would be if tendered in this country for coin of the realm.
Thanks to the kindness of Messrs.

Levin & Co., the bead merchants, of Bevis Marks, E.C., we have been able to get some idea of the more valuable beads, through a selection made by Susi and Chuma in their warehouse.

The Waiyou prefer exceedingly small beads, the size of mustard-seed, and of various colours, but they must be opaque: amongst them dull white chalk varieties, called "Catchokolo," are valuable, besides black and pink, named, respectively, "Bububu" and "Sekundereche" = the "dregs of pombe." One red bead, of various sizes, which has a white centre, is always valuable in every part of Africa.
It is called "Sami-sami" by the Suahele, "Chitakaraka" by the Waiyou, "Mangazi," = "blood," by the Nyassa, and was found popular even amongst the Manyuema, under the name of "Maso-kantussi", "bird's eyes." Whilst speaking of this distant tribe, it is interesting to observe that one peculiar long bead, recognised as common in the Manyuema land, is only sent to the West Coast of Africa, and _never_ to the East.

On Chuma pointing to it as a sort found at the extreme limit explored by Livingstone, it was at once seen that he must have touched that part of Africa which begins to be within the reach of the traders in the Portuguese settlements.
