In the place where the Whang-ho rises, there are more than an hundred springs which sparkle like stars, whence it is called Hotun Nor, the Sea of Stars. These sources form two great lakes called Hala Nor, the black sea or lake; afterwards there appear 3 or 4 little rivers, which join’d form the Whang-ho, which has 8 or 9 branches. These sources of the river are called also Oton-tala. It is in Thibet.

The Whang ho, or as the Portugueze call it Hoam-ho, i.e. the yellow River, rises not far from the source of the Ganges in the Tartarian mountains west of China, and having run thro’ it with a course of more than six hundred leagues, discharges itself into the eastern sea. It hath its name from a yellow mud which always stains its water, and which after rains composes a third part of its quantity. The watermen clear it for use by throwing in alum. The Chinese say its waters cannot become clear in a thousand years; whence it is a common proverb among them for any thing which is never likely to happen, when the yellow river shall run clear.
Note to the Chinese Tale Hau Kiou Choann.

On the way from Macao to Canton in the rivers and channels there is taken a vast quantity of oysters, of whose shells they make glass for the windows.

In the Chinese Novel Hau Kiou Choaan, we read Shueyping-sin ordered her servants to hang up a curtain of mother of pearl across the hall. She commanded the first table to be set for her guest without the curtain and two lighted tapers to be placed upon it. Afterwards she ordered a second table, but without any light, to be set for herself within the curtain, so that she could see every thing thro' it, unseen herself.
As for the wax it is the finest and whitest that may be had tho' of bees: and there is such plenty as serves the whole empire. Several provinces produce it, but that of Huquam exceeds all the others, as well in quantity as whiteness. It is gathered in the province of Xantung upon little trees; but in that of Huquam upon large ones, as big as those of the Indian Pagods, or chesnut-trees in Europe. The way nature has found to produce it, to us appears strange enough. There is in this province a creature, or insect of the bigness of a flea, so sharp at stinging, that it not only pierces the skins of men and beasts, but the boughs and bodies of the trees. Those of the province of Xantung are much valued; where the inhabitants gather their eggs from the trees, and carry them to sell in the province of Huquam. In the spring, there come from these eggs certain worms, which about the beginning of the summer they place at the foot of the tree, whence they creep up, spreading themselves wonderfully over all the branches. Having placed themselves there, they gnaw, pierce, and bore to the very pith, and their nourishment they convert into wax as white as snow, which they drive out to the mouth of the hole they have made, where it remains congealed in drops by the wind, and cold. Then the owners of the trees gather it, and make it into cakes as we do, which are sold about China.

Du Halde's account is somewhat different from this, the worms, he says, fasten on the leaves of the tree, and in a short time form combs of wax, much smaller than the Honey Combs.
