The huts of Darnley Island--together with the inhabitants--have been so fully described in the voyage of the Fly, that it is unnecessary for me to enter upon the subject. The natives always objected to show to us the inside of their huts, many of which we knew were used as dead houses--but Mr. Huxley today was fortunate enough to induce one of them to allow him to enter his house, and make a sketch of the interior, but not until he had given him an axe as an admission fee. These huts resemble a great beehive in shape--a central pole projects beyond the roof, and to this is connected a framework of bamboo, thatched with grass, leaving a single small low entrance to serve as door and window. HUMAN SKULLS OFFERED FOR SALE. Several human skulls were brought down for sale, also a little shrivelled mummy of a child. Some of the former had the skin quite perfect, the nose artificially restored in clay mixed with a resinous substance, and the orbits occupied by a diamond-shaped piece of mother-of-pearl, with a black central mark. Towards the end of the bartering the natives had become very noisy, and even insolent, and everything seemed to indicate that some at least of them were dissatisfied, and inclined to resent some injury or cause of offence, for which purpose apparently they had their bows and arrows ready, and their gauntlets upon the left forearm. Some of them desired me to get into the boat and be off, intended as I understood for a friendly caution, while Dzum came up with an air of profound mystery, wishing me to come with him (now that I was alone) to a neighbouring hut to see a barit which he had brought over for me from Stephens Island. This name is applied to the opossums of the genus Cuscus which the Torres Strait Islanders occasionally procure from New Guinea. However it was time for me to be off, so I contented myself with promising a large reward for the animal if taken off to the ship. The produce of our barter on this and previous occasions amounted to 467 coconuts, 388 pounds of yams* (then very scarce) and 159 pounds of bananas. (*Footnote. Not less than nine different kinds of yams and yam-like tubers--including the sweet-potato--are cultivated in Torres Strait, and are specially distinguished by name.) DZUM AND THE BARIT.
