The fruit of the Olive Tree, an evergreen, now common in the woods of France, Spain, and Italy; but in the wild state producing a small fruit of no value; when cultivated, however, (which it is extensively, both for the fruit and the quant.i.ty of oil which it yields,) it forms one of the richest productions of Southern Europe. The olive came originally from Asia. Its use is very ancient; it is frequently spoken of in the Bible, both as in a wild and cultivated state. The promised land of the Israelites was "a land of oil, olive, and honey." From the time that the dove returned to Noah in the Ark with an "olive leaf plucked off," in all ages and countries, wherever this tree is known, down to the present day, has an olive-branch been the favorite emblem of peace.
What nation holds the olive in great repute?
This tree was a great favorite with the ancient Greeks, and scarcely an ancient custom existed in which the olive was not in some way a.s.sociated: at their marriages and festivals, all parts of their dwellings, especially the doors, were ornamented with them, and the same custom prevails at the present day, both in public and private rejoicings. It was also scarcely less a favorite with the Romans, although it was not held in the same sacred light as amongst the Greeks. The olive-branch has likewise been universally considered the emblem of plenty, and as such, is found on the coins of those countries of which it is _not_ a native. Two centuries after the foundation of Rome, both Italy and Africa were strangers to this useful plant; it afterwards became naturalized in those countries, and at length arrived in Spain, France, &c. Olive trees sometimes attain a great age.
How are the Olives eaten?
The olives while on the tree are intolerably bitter, without any of that peculiar taste which gains them admittance at the richest tables; to fit them for which they are pickled. Ripe olives are eaten in the Eastern countries, especially amongst the Greeks, as an article of food, particularly in Lent. The oil, which they yield in great quant.i.ties, is very highly esteemed; being that chiefly used for salads, &c., in medicine, and in various manufactures.
_Lent_, a time of fasting; the time from Ash-Wednesday to Easter.
How is the Oil drawn from the Olive?
By presses or mills made for the purpose. The sweetest and best olive oil comes from the South of France, from Naples, Florence, and Lucca; quant.i.ties are also brought from Spain and the Ionian Islands.
Where is Naples?
In the South of Italy.
Where are Florence and Lucca situated?
In Italy. Florence is a very ancient, large, and celebrated city, the capital of Italy; Lucca, formerly a republic, belongs now to the kingdom of Italy.
_Republic_, a state in which the supreme power of government is lodged in representatives chosen by the people, instead of being vested in an emperor or king.
You said that the olive is an Evergreen: to what plant or shrub is the term particularly applied?
To any shrub or tree whose leaves continue fresh and green all the year round, winter and summer, as the laurel, pine, cedar, holly, &c., which do not shed their leaves in autumn as other trees.
Is oil a production confined to the Olive alone?
By no means. Oil is a fatty, inflammable matter, drawn from many vegetable and animal bodies. The oils in common use are of three different kinds. The first are mere _oily_ or fatty bodies, extracted either by pressure, or by decoction: of the first kind are those of almonds, nuts, olives, &c.; and of the other, those of different berries, &c., which are procured by boiling the substance in water, which causes the oil to collect on the top.
_Decoction_, act of boiling--a chemical term.
What are the second and third kinds of Oils?
The second are those drawn from vegetables by common distillation in the alembic, with the aid of water; these contain the _oily_ and volatile part of the plant, and are called _essential_ oils. The third sort are those produced by distillation, but of a different kind in an open vessel, and without the help of water. They are likewise divided into _vegetable_ oils, _animal_ oils, and _mineral_ oils; which last are those drawn from amber, and a few other substances partaking both of the vegetable and mineral natures, as Petroleum, commonly known as kerosene or coal oil.
_Alembic_, a chemical vessel used in distilling. It consists of a vessel placed over a fire, containing the substance to be distilled; the upper part, which receives and condenses the steam, is called the head; the beak of this is fitted to a vessel called a receiver.
_Volatile_, easily escaping, quickly flying off.
Whence is the word Oil derived?
From the Latin _oleum_, formed from _olea, olive-tree_, the fruit of which abounds in oil.
What immense fish is it that furnishes us with a quant.i.ty of _animal_ oil?
The Whale, the largest and n.o.blest inhabitant of the waters. It is protected from the cold by a case or coating of blubber, that is, a thick oily fat from which the oil is made; numbers of them are caught for the sake of that. Ambergris, highly prized in perfumery, is a product of the sperm whale.
In what seas are they found?
Chiefly in the Northern Seas: extensive whale fisheries are carried on by the Americans, English, Dutch, &c., and numbers of vessels are sent out for the purpose of taking the fish: they usually sail in the latter end of March, and begin fishing about May. The whale fishery continues generally from that time till the latter end of June or July. There are also other fishes and animals which afford us oils of different kinds, which are used for various purposes in medicine and the arts.
Is the oil called _castor_, which is so much used in medicine, the product of an animal or a plant?
Castor oil is expressed from a West Indian shrub, called Palma Christi; and especially from the ripe seeds, which are full of this oil. It is prepared by collecting these ripe seeds, and freeing them from the husks; then bruising and beating them into a paste; they are next boiled in water, when the oil rising to the surface is skimmed off as it continues to appear. The Castor-oil plant is found growing abundantly in Sumatra, particularly near the sea-sh.o.r.e.
Where is Sumatra situated?
In the Oriental Archipelago, off the south eastern part of the continent of Asia.
In what other countries is this plant found?
In some parts of Africa, Syria, and Egypt. It was anciently cultivated in the two last-mentioned countries in large quant.i.ties, the seeds being used for the oil they yielded, which was burnt in lamps.
[Ill.u.s.tration: BEAVERS BUILDING THEIR HUTS.]
Is not the Palma Christi much affected by soil and situation?
Greatly so. In some places it attains the stature of a tree, and is not a biennial plant, but endures for many years, as in the warm plains of Irak, Arabia, and some parts of Africa.
_Biennial_, lasting for the s.p.a.ce of two years only.
What are Melons?
A species of the Cuc.u.mis, a genus of plants to which the cuc.u.mber belongs. There are great varieties of this fruit cultivated in different parts of the world; that sort called the Cantaleup (so named from being cultivated at a place of that name in the neighborhood of Rome, whither it was brought from Armenia,) is a species of musk-melon; the mature fruit is juicy, and delicately flavored.
Where is Armenia situated?
