"There is a family of poisonous plants, amongst which we may notice the henbane, the datura stramonium, and the tobacco plant. The tobacco plant is perhaps a little less poisonous than the datura, but it is more so than the henbane, which is a violent poison. Here is a tobacco plant--as fine a plant as you can wish to see. It grows to the height of six feet; and from the centre of a tuft of leaves, of a beautiful green, shoot out elegant and graceful clusters of pink flowers. "For a long while the tobacco plant grew unknown and solitary in the wilds of America. The savage to whom we had given brandy gave us in exchange tobacco, with the smoke of which they used to intoxicate themselves on grand occasions. The intercourse between the two worlds began by this amiable interchange of poisons. "Those who first thought of putting tobacco dust up their noses were first laughed at, and then persecuted more or less. James I., of England, wrote against snuff-takers a book entitled _Misocapnos_. Some years later, Pope Urban VIII. excommunicated all persons who took snuff in churches. The Empress Elizabeth thought it necessary to add something to the penalty of excommunication pronounced against those who used the black dust during divine service, and authorised the beadles to confiscate the snuff-boxes to their own use. Amurath IV. forbade the use of snuff under pain of having the nose cut of. "No useful plant could have withstood such attacks. If before this invention a man had been found to say, Let us seek the means of filling the coffers of the state by a voluntary tax; let us set about selling something which every body will like to do without. In America there is a plant essentially poisonous; if from its leaves you extract an empyreumatic oil, a single drop of it will cause an animal to die in horrible convulsions. Suppose we offer this plant for sale chopped up or reduced to a powder. We will sell it very dear, and tell people to stuff the powder up their noses. "'That is to say, I suppose, you will force them to do so by law?' "'Not a bit of it. I spoke of a voluntary tax. As to the portion we chop up, we will tell them to inhale it, and swallow a little of the smoke from it besides.' "'But it will kill them.'
