They were not long, however, allowed to lead so pleasant a life on shore. Adair sent off one of the boats across the channel to the mainland to be in readiness to pounce down on any dhows creeping up on that side, while he himself went away in the pinnace to the southward, accompanied by Gerald and Archie, leaving Jos Green in command of the island. Jerry Bird formed one of the crew, so the party on shore lost their cook. Pango also, one of the escaped slaves, went as interpreter, he having by this time acquired enough English to make himself understood and to understand what was said to him. The boat was provisioned for three weeks, and Adair hoped, by getting fresh food and vegetables from the shore, to be able to stay out longer if necessary. He had on board several articles for barter, and, in addition, a store of empty beer-bottles, for which he had heard the natives have an especial fancy.

Adair’s intention was to examine every opening and indentation in the coast in which a slave dhow could take shelter. He accordingly steered for the mainland, towards the first bay to the south of Angoxa, into which it was possible one of the hoped-for prizes might have crept during the night. On reaching the bay, however, no vessel was to be seen, and the pinnace accordingly stood out again with a light breeze, which enabled her to stand down the coast. The day was passed much as men-of-war’s men are accustomed to spend their time on boat expeditions; the meals were cooked in one pot, common to officers and men, whether “kettler” for dinner or chocolate for breakfast and supper. Pipes were smoked, yarns spun, songs sung, journals written up, and now and then, though not often, books were read. Regular watches were of course kept, and, as a rule, everyone took as much sleep as he could get. The life, as all agreed, was pleasant enough while the weather was fine, but it would be pleasanter to catch a few dhows, send them as prizes into port, and restore the negroes found on board to liberty.

“Faith, I wonder whether we ever shall catch one of those rascals,” exclaimed Desmond, beginning to lose patience when, after three days at sea, not a single dhow had been caught sight of.

“No fear, Gerald,” observed Archie; “they’ll be dropping into our jaws before long if we keep them wide enough open.”

At night the boat was sometimes hove-to, or when the wind was light kept slowly gliding on over the calm surface of the deep. One night Archie Gordon had the middle watch. Scarce a breath filled the sails; the ocean was like glass; not a cloud dimmed the sky, from which the stars shone forth with a brilliancy which afforded light almost equal to that of the full moon; every star, reflected in the mirror-like deep, gave it the appearance of being spangled and streaked with gold. Suddenly there burst forth over the land so vivid a flash of lightning that rocks and trees and the distant hills for a moment stood out in such bold relief, that Archie could not help fancying that the boat had been carried by some unknown current close to the beach. With a cry of surprise he aroused his companions.

“Is anything the matter?” asked Adair, starting up.

“Arrah, what’s in the wind now?” exclaimed Gerald, echoing the question.

“The whole country seems on fire,” answered Archie. “I can by no means make it out.” As he spoke, another flash lighted up, as brilliantly as during the brightest sunshine, the distant hills and wide expanse of ocean. The flashes continued bursting forth in rapid succession, lasting fully ten seconds, with even a less interval between them. Not the slightest sound of distant thunder was heard; silence reigned over the ocean. Even the men, who had roused up their companions to gaze at the wondrous spectacle, uttered not a word. A slight flapping of the sail against the mast, as a catspaw caught it, or an increased ripple of the water against the bows, alone struck the ear.

These brilliant phenomena lasted the greater part of the night.

“It’s very fine,” exclaimed Jerry Bird at last; “but to my mind a sound snooze is more to the purpose than straining our eyes out by winking at it, seeing we can’t say what work may be cut out for us to-morrow; and so I’m going to turn in.”
