As in our own manufacturing counties many thousands of poor mechanics and artisans make little livings for themselves and great fortunes for their employers, so in Tien-sin, the most miserably poor and shrivelled portion of the vast population in China produce a commodity which places their masters, the salt dealers, among the most wealthy merchants in the Empire. While the captain is unloading his cargo I will tell you how these people produce this common edible.

In addition to the pits of salt, which, like coal, are found in many of the provinces, there are many places where it is discovered by scattered spots of gray earth. To obtain this salt, they level the surface of the earth as smooth as glass and in a sloping direction so that the water will run off. When dried by the sun, and the white particles of salt are seen, they first raise it in small heaps, like haycocks, then spread it upon sloping tables with ledges, and pour soft water upon it, which, as it soaks in, extracts the salt and runs into an earthen vessel by means of a small channel. The earth thus drained is not wasted, but laid aside, so that after a few days, when dry, they reduce it to a fine powder, and replace it in the spot from whence it was taken, when, after six days, it is again mixed with particles of salt, which are again extracted as before, so that not one atom becomes lost.

While the men are thus engaged in the fields, the women and children are employed in huts, in boiling the salt water in large iron basins, which they place over an earthen stove, with holes made in such a manner that the fire heats all the basins alike. When the salt water has boiled some time, it becomes thick, and changes slowly into a very white salt, which is stirred with an iron spatula till it becomes quite dry.

When the captain had exchanged his cargo for an other of dates, which he intended again to exchange profitably in Leao-tong for peas and drugs, Nicholas purchased a quantity of furs and mats, which he soon found to be necessary; for, as they approached further to the north, the winds blew keenly, and the iceblocks floated so numerously as frequently to impede their voyage; indeed, the cold was so intense that nothing but the fear of losing life or liberty, or the love of gold, would have induced any one to make the voyage in that inclement season (it was in November). Indeed, by the time they had passed the mouth of the Pei-ho and got into the gulf of Pe-tche-Lee, the snow fell so heavily, and the north winds blew so keenly, that, breaking through all discipline, the sailors lighted fires upon the deck, and laid near them, drinking rice spirit so copiously, that had not Nicholas, who knew so well how to manage such insubordinates, thrown the spirit tubs overboard, they must have foundered upon the Sha-loo-poo-teen islands. As it was, so long and so rough was the passage across the gulf, that the princess became fearfully ill; so much so, indeed, that at one time they feared she would have died. At length, however, they came to an anchor off the coast of Kin-Chow, a distance of seven miles from the shore, and so planted with dangerous rocks that they were compelled to make fire-signals for the townspeople to put off to them in their lighters or barges.

As the people have these lighters always ready for the purpose, it was not long before several answered the signal, and came alongside. Choosing the most commodious, Nicholas caused a large fire to be lighted in the cabin, where the princess, who was too ill to walk, was lifted on board, and the lightermen rowed them the roughest seven miles of their journey. Nicholas and Chow paced the deck in no very good humor, as they were obliged to entrust themselves to the slow movements of the boatmen, who neither for love nor money would hasten their pace. Moreover, as the sea rolled so heavily, the distance was lengthened by their being compelled to take a circuitous course between and around the dangerous rocks.

When the boatman, who, although slow, were sure, brought them beneath the huge rocks which form the sea-walls of Leao-tong, Chow looked up with amazement. "Surely," said he, "Yen-Vang must have built these great rocks to prevent the province from falling upon the heads of the people in his watery dominions;" adding, as he saw some little birds, like swallows, flying about the rocks, "Truly, if my eyeballs are straight, those little creatures promise us some of the soup of life."

"Truly our eyeballs play us false, O Chow, for these birds are seldom found but on the coast of Tonquin, Java, and Cochin-China," said Nicholas doubtfully.

"It is true that the servant has not the wisdom of his master, yet the stomach and the nose are excellent diviners. Moreover, it is said that this bird-nest soup is strengthening to the weak. The princess is weak, O my master, and Chow would obtain some of those nests."

Then, as they were near a jutting point of the rock of no very difficult ascent, Nicholas ordered the barge to stop, while Chow ascended and procured some half-dozen of the nests, from which to the present day, one of the most popular dishes of China is made.

As Nicholas had said, these birds' nests are seldom found except on the coasts of Java, Cochin-China, and Tonquin. The birds are not unlike swallows, as to their feathers; the nests, which they build high up in the clefts of the rocks, are supposed to be composed of small sea-fish, fastened together by means of a viscous juice, which distils from the beaks of the little creatures, and serves as a gum to fasten the nests to the rock. They are also seen to take the froth that floats upon the sea, with which they cement every part of their nests, in the same manner that swallows build with mud and clay. This matter being dried, becomes solid, transparent, and of a greenish color; but, while fresh, it is generally white.
