but to lift our eyes to the great mountain tops looming darkly and grandly on our right; to watch the light pencilling of the cirrus, brushing their summits, as it is drifted toward the north by the rising wind: to watch the changing forms which the clouds assume, from the fleecy horizontal bars of the cirrus, to the denser, gloomier cumulus, prognosticator of storm and rain, which soon settles into a portentous group--Alps above Alps, one above another--and we know the storm which was brewing is at hand, and that it is time to seek shelter. Passing Muikamba, we saw several groves of the tall mvule tree. As far as Bemba the Wabembe occupy the mountain summits, while the Wavira cultivate the alluvial plains along the base and lower slopes of the mountain. At Bemba we halted to take in pieces of pipe-clay, in accordance with the superstition of the Wajiji, who thought us certain of safe passage and good fortune if we complied with the ancient custom. Passing Ngovi, we came to a deep bend, which curved off to Cape Kabogi at the distance of ten miles. About two-thirds of the way we arrived at a group of islets, three in number, all very steep and rocky; the largest about 300 feet in length at the base, and about 200 feet in breadth. Here we made preparations to halt for the night. The inhabitants of the island were a gorgeously-feathered old cock, which was kept as a propitiatory offering to the spirit of the island, a sickly yellow-looking thrush, a hammer-headed stork, and two fish-hawks, who, finding we had taken possession of what had been religiously reserved for them, took flight to the most western island, where from their perches they continued to eye us most solemnly. As these islands were with difficulty pronounced by us as Kavunvweh, the Doctor, seeing that they were the only objects we were likely to discover, named them the "'New York Herald' Islets;" and, in confirmation of the new designation given them, shook hands with me upon it. Careful dead-reckoning settled them to be in lat. 3 degrees 41 minutes S. The summit of the largest island was well adapted to take bearings, and we improved the opportunity, as most extensive views of the broad and lengthy lake and surrounding lines of imposing mountains were attainable. The Ramata Hills were clearly visible, and bore N.N.E. from it; Katanga Cape, S.E. by S.; Sentakeyi, E.S.E.; Magala, E. by N.; south-western point of Muzimu bore S., northern point of Muzimu island, S.S.E. At dawn on the 9th December we prepared to resume our voyage. Once or twice in the night we had been visited by fishermen, but our anxious watchfulness prevented any marauding. It seemed to me, however, that the people of the opposite shore, who were our visitors, were eagerly watching an opportunity to pounce upon our canoe, or take us bodily for a prey; and our men were considerably affected by these thoughts, if we may judge from the hearty good-will with which they rowed away from our late encampment.
