I fear that most of Zanzibar's ships were put there by means of British coin, and not diamond mines, so if Lamoo's men-o'-war were lent her or given to her by Portugal or Germany, it would be simply a matter of diamond cut diamond when the crisis came.

Meanwhile Britain was, to all appearance, hoodwinked. On the coast of Africa her only policy appeared to be to sweep slaving Arab dhows from off the Indian Ocean.

In this she was assisted by other ships of the station, all of which by means of wireless telegraphy were within hail of each other.

Officers going on shore from a ship are usually met by a nigger, who may be of any age from fourteen to forty, only he is always called a boy, and acts for the time being as a city guide or guide through the beautifully-wooded island.

The gentlemen Arabs had their own plan of espionage. In intellect they considered themselves far above a Briton, and in this same art of espionage they undoubtedly were, as well as in every devilish device that might be applied to it.

Never an officer who landed on the white sands but was shadowed, and never even an ordinary seaman. Of a party of these latter they took but little heed, well knowing that as a general rule they betook themselves to some hotel, where they might drink a glass or two, have a song and smoke and yarn and be down in time to the beach to meet the liberty boat. A single officer, or even two, were warily followed whereever they went.

Kep's boy was a clever little rascal, not a day older than himself. A Somali he was, but knew a little English, and plenty of Arabic. As they generally set off to the woods to gather butterflies or lizard-hunting, the Arabs took very little heed of them.

But all the while Kep was picking up the Swahili or Somali language. Out in the forest the two together performed all kinds of monkey tricks, and Kep could soon climb cocoa-nut trees and pitch down the fruit as cleverly even as quick young Bungle. He had some other name, but Bungle suited him well enough, and the lad was rather proud of it than otherwise.

Kep on these little rambles managed to mix a good deal with both low-class and high-class Arabs, but he always kept his ears pricked and his weather-eye lifting.

When in an Arab's house, presumably to drink the splendid coffee which only an Arab can make, Kep pretended not to know a single word of either Somali or Arabic, and thus he gained a considerable deal of information, which was of great use to Captain Breezy.
