A NATIVE OF ARU.

"The trade at Dobbo amounts to something near a hundred thousand dollars a year, and is carried on in the most primitive way. It is almost entirely a barter trade; there is no money in use except copper coins from Java and China, and many of the natives do not even know their value. It requires a great deal of talk to make a bargain, and sometimes they will haggle for hours over a transaction that amounts to only a few cents.

SEA-CUCUMBER.

"The things brought from the islands, and bought by the traders, are pearl-shells, tortoise-shell, edible birds'-nests, pearls, timber, and birds of paradise. There is also a large supply of tripang, or 'beche-de-mer,' of which the Chinese make many soups. It is known in English as the sea-cucumber, and is taken on the reefs and among the rocks all through the Eastern seas, and in some parts of the Pacific Ocean. After being boiled in its own liquid, and dried on racks over a fire, it is ready for market.
