After the Ten Year's War seed of Mexican and United States tobaccos was in great demand to re-seed the ruined vegas, and was introduced in great quantities; and although by a later law the destruction of these exotic species was ordered, that destruction was in fact quite impossible.
Mexican tobaccos (Nicotiana Tabacum, variety macrophyllum) are to-day predominant in a large part of Cuban vegas..
The regie did badly during the first four years of its existence, owing principally to two causes: (1) its ineffectual power to deal with contraband to which the system described above leaves the door wide open; (2) the admission of other than Turkish tobaccos into Egypt, which deprived it at once of about fTioo,000 per annum.
Megvizsgdlasa (Chemical Examination of the most famous Tobaccos of Hungary), by Dr Thomas Kosutany (1877).
From this species the tobaccos of Cuba, the United States, the Philippine Islands and the Latakia of Turkey are derived, and it is also largely cultivated in India; the variety macrophylla is the source of the Maryland tobaccos.
Speaking generally, clay soils retentive of moisture produce heavy-cropping tobaccos which cure to a dark brown or red colour.
Sandy soils produce tobaccos with a thin leaf, curing to a yellow or bright red colour.
Is the normal for ordinary manufacturing and smoking tobaccos, 1 to i z ft.
Cigar tobaccos become coarse if planted too widely.
In the U.S.A., in the cigar tobacco district, fifteen to twenty leaves are often left on each plant, and of manufacturing tobaccos only ten to twelve leaves.
In high quality tobaccos the leaves are " primed " or picked singly as they ripen, but in the great bulk of American tobaccos the whole plant is cut close to the ground when the middle leaves are about ripe.
A very interesting development of quite recent years is that of growing some valuable cigar tobaccos under artificial shade.
Artificial heat may be resorted to in bad weather; in the States, cigar tobaccos and " White Burley " are usually cured in this way.
The view has been put forward that fermentation is due to the activity of bacteria, distinct types occurring in various tobaccos, but the balance of evidence is against it.
When fermentation is completed the tobacco is graded, an operation carried out very carefully in the case of the better cigar tobaccos, and packed for export, cigar tobaccos in bales, and other kinds in hogsheads.
Two years are usually required for ageing, but some tobaccos are kept for four or five years before being manufactured.
When Cuban tobaccos were first introduced into Florida, the type broke up, but by carefully selecting the best plants and using them only as sources of seed for later crops, a good type was obtained.
Thus for wrapper tobaccos, amongst other points a broad, rounded leaf, which will yield perhaps eight wrappers, is much more valuable than a narrow pointed leaf which yields perhaps only four.
Hybridization can also be readily controlled in the case of tobaccos, and in this connexion it is useful to note that, if pollen is desired of some variety growing at a distance, it will retain its vitality for several weeks if kept perfectly dry, and so can readily be sent by post from one place to another.
The successful production of cigar tobaccos from Cuban and Sumatran seed was a development of the late 19th century.
Paper is a monopoly in Greece, and Grecian cigarette manufacturers, to escape the monopoly, have transferred their business to Egypt, where they make cigarettes from Grecian tobaccos by the aid of Greek workmen.
Some of the finest flavoured tobaccos are produced in the regions around Cavalla in Macedonia and ancient Ephesus in Asia Minor.
The cultivation of Turkish tobaccos has been taken up in various parts of the world, e.g.
The increase in favour of packet tobaccos has brought about the invention of elaborate packing machines.
There were 467 tobacco factories reported in 1905 to be engaged in the manufacture of cigars, cheroots, cigarettes, snuff and cut tobaccos for the pipe.
He selected the administration of tobaccos, addressing himself especially to chemical researches under the guidance of Gay-Lussac, and gave striking proof of ability in two papers on the combinations of phosphorus with hydrogen and oxygen, published in Annales de Chimie et de Physique (1835 and 1837).
