The first and second cutters, the launch, and the steam pinnace were each provisioned and sent away to scout along the coast independently of each other, watching for dhows and any suspicious craft we might see making from the mainland for the islands, having orders to capture or destroy such as we found carrying slaves; the Mermaid, our foster-mother, giving us a look-up in turn at our respective stations, to see how we were getting on, and supply us with any stores we might need in the grub and water line.

It was a dreary task.

Sometimes for days we would not sight a sail; and, keeping out to sea, so as to avoid observation from the shore, there was nothing to be seen that could distract one’s attention but the wide-stretching steel-blue surface of the limitless Indian Ocean, and the eternal coppery sky overhead, with never a cloud to shade us from the ever-blazing sun.

The south-west monsoon was in full swing, and the weather, consequently, was cooler than usual—that was one comfort; but, the irksomeness of our life was almost unbearable, and we all longed for something to happen, no matter what, to break the monotony of our perpetual patrol.

Of course, we did come across some dhows, one in particular, a large ‘bagala,’ a craft with a high square stern, and a prow like a goose-neck; while her poop resembled that of a Chinese junk, being only a trifle clumsier—if possible.

We overhauled this hooker between Zanzibar and Pemba; and, as she was making for the latter island, where cloves are grown and a large number of slaves employed in their cultivation, the trade being the most important on the coast, we naturally thought we were going to make a big haul and get no end of bounty for the capture of the dhow.

But, as luck would have it, when we boarded her, not a single nigger was aboard, nor was there any sign about her to show that she was fitted out for the contraband business, there being no second bamboo deck betwixt her hold and the upper one, which the slavers always have; and, though we rummaged her fore and aft, we could not tumble upon the special stock of rice and barricoes of water, which are always carried for the accommodation of the ebony passengers, if they have any.

No, all was in order; her ‘reis,’ or skipper, a swarthy Arab, with the most diabolical expression I ever saw on human face, showing us his clearance paper, which had the stamp of the British Consulate, and described that he was bound on a trading voyage to Muscat.

So we had to let him pass, the old rascal of a ‘reis’ grinning over her stern at us as the bagala made off, running before the wind; the hook-nosed Arab looking as pleased as Punch, and yet having a sort of sly, malicious twinkle in his eye, like that ‘Old Nick’ probably puts on ‘when he catches a churchwarden robbing a till,’ as Larrikins said.

No wonder the old slave-dealer sniggered to himself; for we heard afterwards that he put in at Pangani the same night, after we were out of sight, beating down to the southward, and succeeded in running a cargo of the usual sort, the proceeds of the trip enabling him to retire from business and set up as a holy man for the rest of his life.
