The kernel, being taken out and dried in the sun, is boiled in water; by which process a white, firm, and rich-flavored butter is produced, which will keep for a whole year without salt. The growth and preparation of this commodity is one of the first objects of African industry, and forms a principal article of their trade with one another. You have given me an account of a useful Butter prepared from a plant; is there not also a tree which can supply the want of a cow? In South America there is a tree, the juice of which is a nourishing milk; it is called the Cow Tree. This tree is very fine; the leaves are broad, and some of them ten inches long; the fruit is rather fleshy, and contains one or two nuts or kernels. The milk is very abundant, and is procured by incisions made in the trunk of the tree; it is tolerably thick, and of a glutinous quality, a pleasant taste, and agreeable smell. The negroes and people at work on the farms drink it, dipping into it their bread made of maize. _Glutinous_, having the quality of glue,--an adhesive, gummy substance, prepared from the skins of animals: it is used in joining wood, &c., and for many other purposes. What time of the day is the best for drawing the juice? Sunrise; the blacks and natives then hasten from all quarters with large bowls to receive the milk; some drink it on the spot, others carry it home to their families. What island possesses a remarkable substitute for the want of springs of Water? Ferro, one of the Canary Isles, situated in the Atlantic Ocean. In this island there is no water, except on a part of the beach which is nearly inaccessible; to supply the place of a fountain, Nature has bestowed on the island a particular kind of tree, unknown in other parts of the world. It is of a moderate size, with straight, long, evergreen leaves; on its top a small cloud continually rests, which so drenches the leaves with moisture, that it perpetually distils upon the ground a stream of clear water. To these trees, as to perennial springs, the inhabitants of Ferro repair, and are supplied with abundance of water for themselves and cattle. _Perennial_, lasting through the year, perpetual. What is Licorice? A plant, the juice of which is squeezed from the roots, and then boiled with sugar, and used as a remedy for coughs, &c. Great quantities are exported from Spain, Italy, &c. The dried root is of great use in medicine, and makes an excellent drink for colds and other affections of the lungs by boiling it with linseed. What are the Lungs? The organs of respiration in man and many other animals. There are two of these organs, one on each side of the chest. _Respiration_, breathing; the act of inhaling air into the lungs, and again expelling it, by which animal life is supported. What is Manna?
