Leech is a popular term for annelidworms of the class Hirudinea comprising those worms equipped with a sucker at each end that draw blood from their prey (warm blooded mammals), such as Hirudo medicinalis. Leeches live in hot, swampy areas particularly in stagnant water and feed on the blood of passing mammals. Pulling a leech off can result in the jaw being left in the skin, and an infection resulting. The prefered method for removing leeches in the wild is to touch them with the lighted end of a cigarette, causing the leech to release its grip and drop off. Research Leech
Tobacco is the name given to the leaves of those varieties of the Nicotiana which are prepared in different forms for use as a narcotic. It is generally manufactured for smoking, but also for chewing and as snuth.
The word tobacco is probably derived from tobaco, the name given to a peculiar Y-shaped instrument used by the old inhabitants of the island of Santo Domingo for inhaling tobacco-smoke through the nostrils. Other authorities claim that the name of the herb is derived from the Mexican word tabacco. Columbus and his party made the earliest European reference to tobacco on their return from the voyage to Cuba in 1492. The tobacco plant was first brought to Europe in 1558 by Francisco Fernandes, a Spanish physician. The wonderful healing properties which the plant was supposed to possess caused the habit of smoking and snuff-taking to spread with great rapidity over almost the whole of Europe. Jean Nicot, French ambassador to Portugal, who gives his name to the genusNicotiana, sent a present of tobacco seeds to Catherine de'Medici, and she initiated in France the snuff-taking habit as a cure for headache. This habit soon spread to Scotland and Ireland, where it remained popular long after the smoking habit had become established in England.
The smoking of tobacco was really started by English example. In 1586, Ralph Lane, the first governor of Virginia, and Sir Francis Drake brought smoking materials and implements to Sir Walter Raleigh, who very rapidly popularised the custom.
Most of the tobacco used in the 17th and 18th centuries was grown in Virginia by English colonists, whose industry was carefully protected by laws prohibiting the production of tobacco in the British Isles.
There are about 50 species of Nicotiana, most of them indigenous to America. Of these, three varieties are in general use by smokers: (1) Nicotiana tabacum, the Virginian variety, originally derived from the South or Central American seed, and now cultivated in almost all temperate and warmer climates. (2) Nicotianarustica, grown principally in Turkey, Syria, and India. This is milder in flavour, and is principally used for the manufacture of cigarettes. It burns too quickly for a pipe tobacco. (3) Nicotiana Persica, or Persian tobacco, which is good for pipe tobacco, but not sufficiently uniform for the manufacture of cigars.
The tobacco plant is a coarse, rank-growing annual. Its stem is simple and unbranched, and grows to a height of about two meters, terminating in a bunch of yellow or rose-coloured flowers. The East Indian variety is slightly different, producing a green tobacco from a smaller plant. It is derived from the Mexican seed, and is also cultivated in Southern Germany and Hungary.
The tobacco plant can be cultivated in every part of the world, but with widely varying measures of success. It is grown in British gardens for the sake of its flowers. Clayey, moist soils produce tobaccos which are dark brown or reddish in colour when cured. Bright and yellow tobaccos are grown on sandy soils, and the leaf of this variety is thinner. The bright tobacco produced in Virginia and North Carolina is all grown in loose sandy soil with a clay subsoil.
The tobacco seeds are generally sown in nursery beds, and set out later. About 3OOOOO to 4000000 go to the ounce, and this produces about 40,000 plants, for which 50 square yards of nursery bed are sufficient. The seeds are sown at the end of March or beginning of April, in rich, heavy soil which has been carefully prepared and fertilised. The seedlings remain in the nursery from fifty to sixty days, during which time the fields are well tilled and manured. Transplanting is done on a warm, rainy day, and the young plants set in ridges varying from one to four feet in width. Ridges of one to one and a half feet are most usual in Cuba and Sumatra, as the wider ridge produces a leaf which is too coarse for the purpose of cigar-making.
The crop takes another two months until it flowers, and at this stage the buds are pinched off or 'topped', and some of the leaves pruned, so that only a certain number are left to ripen. For cigar-tobacco, from 15 to 20 leaves are left on the plant; for the best smoking tobaccos, 10 to 12 leaves. Plants which have been topped form suckers, and in Florida these are left to produce a second, although inferior, sucker crop.
The leaves take about 35 days to ripen after the plants are topped and pruned. The ripening leaf changes from a dark to a lighter yellowish-green colour, and is often mottled and becomes gummy. The ripe leaf cracks and creases when folded. The lower leaves ripen first, and for the best tobaccos the leaves are picked singly ;
as they ripen. For the bulk of the tobaccos, however, the whole plant is cut when the middle leaves are ripe. Warm, cloudy days are best for cutting, and the plants are not gathered in hot sunshine or when they are wet from rain or dew.
After harvesting the plants are left in the open to wilt, and are then conveyed to the drying-house or ventilating-barn, where they are straddled across tiers of poles and dried in a temperature which is raised to 170° F for four to five days. On damp days the moisture is allowed to penetrate into the drying-house to make the leaves pliable.
The plants are then taken down and stripped, and the leaves sorted into firsts, seconds, and lugs - the name given to the inferior leaves. They are formed into hands containing ten to twelve leaves, and these are left in heaps and fermented at a temperature of about 130° F for from three to four weeks. The heaps are shuffled from time to time, to allow all the leaves to assume a uniform brown tint. This process is called the fermenting or sweetening process. In the non-fermenting processes the leaves are simply sun-cured, or sun-dried, and this tobacco is used chiefly for chewing tobaccos. In the fermenting process the starch and sugar in the leaf are decomposed, but they are retained in the sun-dried process. Lastly, the leaves are packed carefully in hogsheads for shipment.
Tobacco leaf is used for making into various smoking mixtures, roll tobacco, cake or plug, cigars, cigarettes, and snuff. For snuff the leaf requires very careful fermentation during several weeks. It is ground up and flavoured so as to produce the greatest possible amount of free ammonia, free nicotine, and other aromatic scents. Syria produces and manufactures a smoking tobacco which is known as Latakia. It is similar to Turkish-grown tobacco, but differently treated. The plants are not topped. The seeds as well as the leaves are included in the curing, this taking place in the smoke of a fire of evergreen-oak, which gives a black colour and a peculiarly strong flavour to the tobacco.
Tobacco for pipe-smoking is mostly grown in the USA, the chief states being Kentucky, North Carolina, and Virginia. Louisiana grows a dark, almost black, and very strong tobacco known as perique. Cigarette tobaccos are principally imported from Virginia, and Turkish and Egyptian cigarettes are also in great demand. The Egyptian cigarette is made from Turkish leaf, as the cultivation of tobacco in Egypt was prohibited in 1891. The best cigar tobaccos are grown in Cuba. A very good cigar leaf is also produced in Jamaica, Sumatra and North Borneo.
Since the introduction of tobacco into England, it has been subject to continuous legislation and import duties. In the early days a certain quantity of tobacco was grown in England for domestic consumption, and quite a considerable trade was done with Turkey, which, at that time, imported her tobacco supplies from England. Queen Elizabeth imposed a tax of 2d per Ib on imported tobacco. In 1621 James I increased this to 6s. lOd. per Ib.
During the American War of Independence, England's source of supply and the revenue there from were temporarily suspended, and tobacco was again widely planted in England, although the prohibition laws had not been repealed. These laws had never applied to Scotland, and to reimburse themselves for the loss of revenue during the non-importation of American tobacco, the Government purchased the Scotch tobacco crops at the fixed price of 4d. per Ib., thus temporarily creating a Government monopoly in tobacco. The ban on the growing of tobacco in the British Isles, renewed in 1782 in England, and in 1830 in Ireland, was modified later in the 19th century, and tobacco can now be cultivated under licence.
During the late 20th century an American-led ban on tobacco smoking supposedly because of the connection with lung cancer, but more likely under pressure from the pharmaceutical lobby, in public places slowly extended to Britain, with Scotland banning the smoking of tobacco in pubs and clubs in 2005.

Ghede, in the original myths of Haiti, was the god of love, sex incarnate. In later, Voodoo myth he was amalgamated with BaronSamedi, god of death. He kept his earlier lustful ways, and a fondness for rum and feasting. He was a dandy, always wearing a black tail-coat, a top hat and sunglasses, twirling a cane and smoking a cigar or a cigarette in a long holder. He loved to dance, and swept his followers away into the ecstasy and trance of dancing. But the dance, which originally was a phallic ritual of birth, had now become a dance of death: Baron Samedi's orgies always ended (for his mortal followers) at the crossroads between this world and the Underworld, and the way they went was down. Because Ghede was Guardian of the Crossroads, he knew all the secrets of magic, and had second hearing and second sight. He could be consulted for advice - often on questions of fertility, either of humans, crops or animals. The questioner made blood-sacrifice and asked the priest questions to put to Ghede, and the god answered in the patterns of
rum-drops spilled in the dust, or in the hll of dice or the turning of Tarot cards. The advice was often frightening and apparently ridiculous, but it was always true and you neglected it at your peril. Research Ghede
Propylene oxide is a colourless liquid with an ether-like odour that is used mainly as a chemical intermediate in the production of polyurethane polyols, which are used to make polyurethane foams, coatings, and adhesives. It is used in the manufacture of propylene glycol, which is used in fibreglass-reinforced plastics, foods, cosmetics, pharmaceuticals, cigarettetobacco, packaging materials, dyes, and hydraulic fluids. It is also used in the preparation of glycol ethers, dipropylene glycol, industrial polyglycols, lubricants, surfactants, oil demulsifiers, isopropanolamines, and as a solvent and soil sterilant. It is used in fumigationchambers for the sterilization of packaged foods; as a stabilizer for methylene chloride, fuel, and heating oils; in treating wood for termite resistance; as an acid scavenger and pH control agent; for removing residual catalysts from crude polyolefins; in fuel-air explosives in munitions; and as a component of Zeospan, a polyether rubber. Propylene oxide is a volatile, flammable liquid
that is soluble in water, alcohol, and ether. It is highly dangerous when exposed to heat or flame. It has a violent reaction with hydrogen chloride, chlorosulphonic acid, hydrogenfluoride, and oleum. It should not be stored in the presence of acids, bases, chlorides of iron, aluminum, and tin, or peroxides of iron and aluminum; any of these may cause violent polymerization.
Propylene oxide is miscible with most organic solvents, and forms a two-layer system with water. It is incompatible with anhydrous metal chlorides, iron, strong acids, caustics, and peroxides, and reacts vigorously with oxidizing materials. When exposed to flame, propylene oxide can explode. Polymerization may occur due to high temperatures or contamination with alkalis, aqueous acids, amines, and acidic alcohols.
Propylene oxide is also known as epoxypropane; 1,2-epoxypropane; methyl ethylene oxide; methyl oxirane; propene oxide; and 1,2-propylene oxide. Derivatives of
propylene oxide are polyether polyols; propylene glycol; di- and tripropylene glycol; poly (propylene glycol)s; surfactants; glycol ethers; and isopropanolamines. Research Propylene oxide
