The Arab here referred to the fact that the period of the year allowed by treaty for the “lawful slave-trade” of the Zanzibar dominions had come to an end. That period extended over several months, and during its course passes from the Sultan secured “domestic slavers” against the British cruisers. After its expiration no export of slaves was permitted anywhere; nevertheless a very large export was carried on, despite non-permission and cruisers. Yoosoof meant to run the blockade and take his chance.

“How many dhows have you got?” asked Yoosoof.

“Three,” replied Moosa.

“That will do,” returned the Arab after a few minutes’ thought; “it will be a tight fit at first, perhaps, but a few days at sea will rectify that. Even in the most healthy season and favourable conditions we must unfortunately count on a good many losses. We shall sail to-morrow.”

The morrow came, and three dhows left the harbour of Kilwa, hoisted their lateen sails, and steered northwards.

They were densely crowded with slaves. Even to the eye of a superficial observer this would have been patent, for the upper deck of each was so closely packed with black men, women, and children, that a square inch of it could not anywhere be seen.

They were packed very systematically, in order to secure economical stowage. Each human being sat on his haunches with his thighs against his breast, and his knees touching his chin. They were all ranged thus in rows, shoulder to shoulder, and back to shin, so that the deck was covered with a solid phalanx of human flesh. Change of posture was not provided for: it was not possible. There was no awning over the upper deck. The tropical sun poured its rays on the heads of the slaves all day. The dews fell on them all night. The voyage might last for days or weeks, but there was no relief to the wretched multitude. For no purpose whatever could they move from their terrible position, save for the one purpose of being thrown overboard when dead.

But we have only spoken of the upper deck of these dhows. Beneath this there was a temporary bamboo deck, with just space sufficient to admit of men being seated in the position above referred to. This was also crowded, but it was not the “Black Hole” of the vessel. That was lower still. Seated on the stone ballast beneath the bamboo deck there was yet another layer of humanity, whose condition can neither be described nor conceived. Without air, without light, without room to move, without hope; with insufferable stench, with hunger and thirst, with heat unbearable, with agony of body and soul, with dread anticipations of the future, and despairing memories of the past, they sat for days and nights together—fed with just enough of uncooked rice and water to keep soul and body together.

Not enough in all cases, however, for many succumbed, especially among the women and children.

Down in the lowest, filthiest, and darkest corner of this foul hold sat Kambira, with little Obo crushed against his shins. It may be supposed that there was a touch of mercy in this arrangement. Let not the reader suppose so. Yoosoof knew that if Kambira was to be got to market alive, Obo must go along with him. Moosa also knew that if the strong-minded chief was to be subdued at all, it would only be by the most terrible means. Hence his position in the dhow.
