So much has been said for and against this tree, usually supposed to be fabulous, that we looked upon it with great curiosity; and although aware that its noxious qualities have been much exaggerated, we were anxious to test its powers, if we could. We procured a ladder, which we raised against the tree, and one of our party ascended to the uppermost branches without experiencing the fainting sensation ascribed to be produced by close contact with its foliage. We then tapped the tree at the bottom, and there issued from it a white viscous fluid, which the natives asserted to be a virulent poison, and used by them for dipping the points of their arrows. We carried off a bottle of this poison, and having drunk from the fountain beneath the tree, without fear and without injury, we went away. This was the only specimen of the upas tree that I saw in Borneo. The lower orders at Bruni, in addition to a jacket and trousers, wear an immense straw hat of a conical shape, with a brim as wide as an umbrella. This hat, unless thrown back on the shoulders, entirely conceals the face. At times, when the river is crowded with canoes, nothing is to be seen but a mass of these straw hats, which present a very strange appearance. But the greatest novelty at Bruni is the floating bazaar. There are no shops in the city, and the market is held every day in canoes. These come in at sunrise every morning from every part of the river, laden with fresh fruit, tobacco, pepper, and every other article which is produced in the vicinity; a few European productions, such as handkerchiefs, check-cotton prints, &c., also make their appearance. Congregated in the main street the canoes are tacked together, forming lanes through which the purchasers, in their own canoes, paddle, selecting and bargaining for their goods with as much convenience as if the whole was transacted on terra firma. Iron is here so valuable that it is used as money. One hundred flat pieces an inch square are valued at a dollar, and among the lower classes these iron pieces form the sole coin. They are unstamped, so that every person appears to be at liberty to cut his own iron into money; but whether such is really the case I cannot vouch. We remained at Bruni for a week, during which time a great deal of diplomatic duty was got through by the seniors of the party, leaving the juniors to amuse themselves with discovering fresh objects of interest, and illustrating every thing worthy of notice.
