During our stay here we were all very busy. Our captain was daily superintending the completion of his two small praus. All day long native boats were coming with fish, cocoa-nuts, parrots and lories, earthen pans, sirip leaf, wooden bowls, and trays, &c. &e., which every one of the fifty inhabitants of our prau seemed to be buying on his own account, till all available and most unavailable space of our vessel was occupied with these miscellaneous articles: for every man on board a prau considers himself at liberty to trade, and to carry with him whatever he can afford to buy.
Money is unknown and valueless here--knives, cloth, and arrack forming the only medium of exchange, with tobacco for small coin. Every transaction is the subject of a special bargain, and the cause of much talking. It is absolutely necessary to offer very little, as the natives are never satisfied till you add a little more. They are then far better pleased than if you had given them twice the amount at first and refused to increase it.
I, too, was doing a little business, having persuaded some of the natives to collect insects for me; and when they really found that I gave them most fragrant tobacco for worthless black and green beetles, I soon had scores of visitors, men, women, and children, bringing bamboos full of creeping things, which, alas! too frequently had eaten each other into fragments during the tedium of a day's confinement. Of one grand new beetle, glittering with ruby and emerald tints, I got a large quantity, having first detected one of its wing-cases ornamenting the outside of a native's tobacco pouch. It was quite a new species, and had not been found elsewhere than on this little island. It is one of the Buprestidae, and has been named Cyphogastra calepyga.
Each morning after an early breakfast I wandered by myself into the forest, where I found delightful occupation in capturing the large and handsome butterflies, which were tolerably abundant, and most of them new to me; for I was now upon the confines of the Moluccas and New Guinea,--a region the productions of which were then among the most precious and rare in the cabinets of Europe. Here my eyes were feasted for the first time with splendid scarlet lories on the wing, as well as by the sight of that most imperial butterfly, the "Priamus" of collectors, or a closely allied species, but flying so high that I did not succeed in capturing a specimen. One of them was brought me in a bamboo, bored up with a lot of beetles, and of course torn to pieces. The principal drawback of the place for a collector is the want of good paths, and the dreadfully rugged character of the surface, requiring the attention to be so continually directed to securing a footing, as to make it very difficult to capture active winged things, who pass out of reach while one is glancing to see that the next step may not plunge one into a chasm or over a precipice. Another inconvenience is that there are no running streams, the rock being of so porous a nature that the surface-water everywhere penetrates its fissures; at least such is the character of the neighbourhood we visited, the only water being small springs trickling out close to the sea-beach.
