The children all united in begging to hear this account; upon which Mrs. Bernard took it from her pocket, and read the following extract: "The esculent martin is said to less in size than the wren. The bill is thick; the upper parts of the body brown, and the under parts white. The tail is forked, and each feather is tipped with white. The legs are brown. "The nest of this bird is excessively curious, and composed of such materials, that it is not only eatable, but is considered one of the greatest dainties that the Asiatic epicures possess. It generally weighs about half an ounce, and is, in shape, like half a lemon; or, as some say, like a saucer with one side flatted, which adheres to the rock. The texture is somewhat like isinglass, or rather more like fine gum-dragon; and the several layers of the matter it is composed of, are very apparent; being fabricated from repeated parcels of a soft slimy substance, in the same manner as the common martins form theirs of mud. Authors differ much as to the materials of which it is composed: some suppose it to consist of sea-worms, of the mollusca kind; others, of a kind of cuttle-fish, or a glutinous sea-plast called agal-agal. It has also been supposed, that the swallows rob other birds of their eggs, and, after breaking the shells, apply the white of them to that purpose. "The best sorts of nests, which are perfectly free from dirt, are dissolved in broths, in order to thicken them, and are said to give them an exquisite flavour. They are soaked in water to soften, then pulled to pices, and, after being mixed with ginseng, are put into the body of a fowl. The whole is then stewed in a pot, with a sufficient quantity of water, and left on the coals all night. The following morning it is ready to be eaten." "Pray, mamma, what is _ginseng?_ I never heard of it before," said Louisa. _Mrs. B._ It is the root of a small plant, growing in China, Tartary, and likewise in some parts of North America, particularly Canada and Pennsylvania, from whence considerable quantities have lately been brought over here. Amongst the Chinese, it is esteemed a medicine of extraordinary value. "A medicine! mamma," exclaimed Louisa; "I thought you said they put it into the stuffing of their fowl!" "And so they do, my dear," returned Mrs. Bernard, "it is by no means of an unpleasant taste, as it has a mucilaginous sweetness, approaching to that of liquorice, accompanied with an agreeable bitterness, and a slight aromatic warmth, with little or no smell." _Louisa._ Thank you mamma. Now will you go on with your account? _Mrs. B._ "The nests of which I was speaking, are found in vast numbers in many islands of the Eastern Archipelago. The best kind sell in China, from one thousand to fifteen hundred dollars the picle, a weight of about twenty-five pounds. The black and dirty ones only sell for twenty dollars.
