The weather now set seriously against us. The thermometer fell some 5° (F.), and heavy showers, mostly in the morning, wetted us clean through, despite all precautions. Lightning from the N. West appeared; the ‘egg of the cloud’ showed the focus of electric matter, and tornados, exactly resembling those of the Guinea coast, made the crew down sail, and satisfy themselves with one knot an hour. They had a peculiar style of keeping watch; all sat up singing till 10-11 P. M., after which every man slept as unanimously. The only waker was poor Said, who with red eyes and peeling nose suffered crispations when the squalls came on. About 9 A. M. (January 10) we sighted for the first time Pemba, the Emerald Isle of these Eastern Seas; and after three days’ stumbling over 33 miles from Kokoto-ni, Pemba channel, with the hills of the Mrima clear on our left, appeared at 3 P. M. To the right rose the tree-grown banks, and the verdant coral-ledges, which have given a name to the Green Island of the Arabs. Except from the mast-head it is invisible at an offing of 12 miles, this forest-clump emerging from the blue and buoyant wave, and therefore it was neglected by the Periplus. In A. D. 1698 the bold buccaneer Captain Kidd here buried his blood-stained hoards of gold and jewels, the plunder of India and of the further Orient. The people have found pots of ‘nuggets,’ probably intended for buttons, in order that the pirate might wear his wealth. Thus it is that the modern skipper, landing at Madagascar, or other robber haunts of the older day, still frequently witnesses the disappearance of his brass buttons, whilst the edge of a knife resting upon his throat secures the quiescence essential to the rapid performance of the operation.
