Blue Peacock was the sexy code name of a secret British plan to salt the Rhine with nuclear mines in the 1950s, in case of war.
Less sexily, they planned to put a live chicken in each one, to keep the electronics from getting cold.
When the file was declassified on April 1, 2004, this was taken to be an April Fool’s joke, but it’s true. Fortunately, the project was canceled.
Cures, from John Aubrey, Miscellanies Upon Various Subjects, 1696:
The land regions of Mars can be distinguished from the seas by their ruddy color, the seas being greenish. But here, perhaps, you will be disposed to ask how astronomers can be sure that the greenish regions are seas, the ruddy regions land, the white spots either snow or cloud. Might not materials altogether unlike any we are acquainted with exist upon that remote planet?
The spectroscope answers this question in the clearest way. You may remember what I told you in October, 1876, about Venus, how astronomers have learned that the vapor of water exists in her atmosphere. The same method has been applied, even more satisfactorily, to the planet of war, and it has been found that he also has his atmosphere at times laden with moisture. This being so, it is clear we have not to do with a planet made of materials utterly unlike those forming our earth. To suppose so, when we find that the air of Mars, formed like our own (for if it contained other gases the spectroscope would tell us), contains often large quantities of the vapor of water, would be as absurd as to believe in the green cheese theory of the moon, or in another equally preposterous, advanced lately by an English artist — Mr. J.T. Brett — to the effect that the atmosphere of Venus is formed of glass.

Recipe for “flying ointment”:
Allegedly such recipes were obtained by torturing accused witches, who said they used the ointment to fly to the Sabbat. More likely the mixture induced hallucinations; maybe that amounts to the same thing.
The Russians’ “tsar tank” (above) didn’t work in World War I, and their “winged tank” (below) didn’t work in World War II.
No matter. “Failure is not falling down,” runs an Asian proverb, “but refusing to get up.”
When Magellan reached Argentina in 1519, he was in for a shock:
One day we suddenly saw a naked man of giant stature on the shore of the port, dancing, singing, and throwing dust on his head. The captain-general sent one of our men to the giant so that he might perform the same actions as a sign of peace. … He was so tall that we reached only to his waist, and he was well proportioned …
The navigator’s account says the man was “10 spans high,” which would be 7 foot 6; later European explorers reported natives up to 15 feet tall.
These legends persisted for 250 years before they were debunked, and they left one permanent legacy: Patagonia means “land of the big feet.”

Letter received by William McKinley in April 1898, shortly before the outbreak of the Spanish-American War:
Dear Sir I for one feel Confident that your good judgment will carry America safely through without war —
But in case of such an event I am ready to place a Company of fifty Lady sharpshooters at your disposal. Every one of them will be an American and as they will furnish their own arms and ammunition will be little if any expense to the government.
Very truly
Annie Oakley
Treatment for sore throat, diphtheria, and scarlet fever from The Confederate Receipt Book, 1868:
Mix in a common size cup of fresh milk two teaspoonfuls of pulverized charcoal and ten drops of spirits of turpentine. Soften the charcoal with a few drops of milk before putting into the cup. Gargle frequently, according to the violence of the symptoms.
A letter to the Seattle Bureau of Prohibition, Sept. 12, 1931:
Dear Sir:
My husband is in the habit of buying a quart of wiskey every other day from a Chinese bootlegger named Chin Waugh living at 317-16th near Alder street.
We need this money for household expenses. Will you please have his place raided? He keeps a supply planted in the garden and a smaller quantity under the back steps for quick delivery. If you make the raid at 9:30 any morning you will be sure to get the goods and Chin also as he leaves the house at 10 o’clock and may clean up before he goes.
Thanking you in advance, I remain yours truly,
Mrs. Hillyer
