The usual measure by which they are sold is the frasilah, containing a weight of about 70 lbs. Livingstone, Cameron and Stanley always took care to be well provided with this kind of currency. In default of beads, the picé, a Zanzibar coin worth something more than a farthing, and vioon-gooas, shells peculiar to the East Coast, are recognized as a medium of exchange in the market. Amongst the cannibal tribes a certain value is attached to human teeth, and at the lakoni some natives might be seen wearing strings of teeth, the owners of which they had probably, at some previous time, devoured. This species of currency, however, was falling rapidly into disuse.
Towards the middle of the day the excitement of the market reached its highest pitch, and the uproar became perfectly deafening. The voices of the eager sellers mingled with those of indignant and overcharged customers; fights were numerous, and as there was an utter absence of any kind of police, no effort was made to restore peace or order amongst the unruly crowd.
It was just noon when Alvez gave orders that the slaves he wished to dispose of should be placed on view. Thereupon nearly two thousand unfortunates were brought forward, many of whom had been confined in the dealer's barracks for several months. Most of the stock, however, had been so carefully attended to that they were in good condition, and it was only the last batch that looked as if they would be improved by another month's rest; but as the demand upon the East Coast was now very large, Alvez hoped to get a good price for all, and determined to part with even the last arrivals for whatever sum he could obtain.
Amongst these latter, whom the havildars drove like a herd of cattle into the middle of the chitoka, were Tom and his three friends. They were closely chained, and rage and shame were depicted in their countenances.
Bat passed a quick and scrutinizing gaze around him, and said to the others,-
"I do not see Mr. Dick."
Tom answered mournfully,-
"Mr. Dick will be killed, if he is not dead already. Our only hope is that we may now all be bought in one lot; it will be a consolation to us if we can be all together."
Tears rose to Bat's eyes as he thought of how his poor old father was likely to be sold, and carried away to wear out his days as a common slave.
The sale now commenced. The agents of Alvez proceeded to divide the slaves, men, women and children, into lots, treating them in no respect better than beasts in a cattle-market. Tom and the others were paraded about from customer to customer, an agent accompanying them to proclaim the price demanded. Strong, intelligent-looking Americans, quite different to the miserable creatures brought from the banks of the Zambesi and Lualaba, they at once attracted the observation of the Arab and half-breed dealers. Just as though they were examining a horse, the buyers felt their limbs, turned them round and round, looked at their teeth, and finally tested their paces by throwing a stick to a distance and making them run to fetch it.
