A rope is passed over a pulley. It has a weight at one end and a monkey at the other. There is the same length of rope on either side and equilibrium is maintained. The rope weighs four ounces per foot. The age of the monkey and the age of the monkey’s mother together total four years. The weight of the monkey is as many pounds as the monkey’s mother is years old. The monkey’s mother is twice as old as the monkey was when the monkey’s mother was half as old as the monkey will be when the monkey is three times as old as the monkey’s mother was when the monkey’s mother was three times as old as the monkey. The weight of the rope and the weight at the end is half as much again as the difference in weight between the weight of the weight and the weight and the weight of the monkey. Now, what is the length of the rope?

“Almost Too Strange for Credence”
We all went over to Mannheim, and dined at the hotel where, seventeen years before, I, being fourteen months old, was given away to my aunt, who was also my godmother, to live with her forever as if I were her own child, and never to see my own parents, as such, any more. … When we returned to the station in the evening, we had a long time to wait for the train. On the platform was a poor woman, crying very bitterly, with a little child in her arms. Emmie Penrhyn, who was tender-hearted, went up to her, and said she was afraid she was in some great trouble. ‘Yes,’ she said, ‘it is about my little child. My little child, who is only fourteen months old, is going away from me forever in the train which is coming. It is going away to be adopted by its aunt, who is also its godmother, and I shall never, never have anything to do with it any more.’ It was of an adoption under exactly the same circumstances that we had been to Mannheim to keep the seventeenth anniversary!

Math Notes
The Plague Village
In 1665, the Black Death came to Eyam in Derbyshire.
To prevent the spread of the disease, the entire village quarantined itself. In the ensuing year, its population dropped from 350 to 83.
The gravedigger survived.
Pulp Friction
Each February, the residents of Ivrea, Italy, throw oranges at each other. On the three days preceding Shrove Tuesday, thousands of costumed “revolutionaries” battle an “aristocracy” by hurling citrus fruits. Supposedly this commemorates a droit de seigneur drama in the 12th century, but in practice it’s just a bunch of people throwing oranges.
Eight hundred miles to the west, they’re throwing tomatoes.
Giglioli’s Whale
In 1867, off the coast of Chile, zoologist Enrico Giglioli spotted a whale with two dorsal fins, a feature unheard of in any known whale.
A similar whale was spotted off Scotland in 1868, and another more than a century later near Corsica.
If “Giglioli’s whale” exists, it’s been spotted only three times, and no specimen, living or dead, and has ever been captured.

Help Wanted
H. Hamilton, once the proprietor of Payne’s Hill, near Cobham, Surrey, advertised for a person who was willing to become a hermit in that beautiful retreat of his. The conditions were, that he was to continue in the hermitage seven years, where he should be provided with a Bible, optical glasses, a mat for his bed, a hassock for his pillow, an hour-glass for his timepiece, water for his beverage, food from the house, but never to exchange a syllable with the servant. He was to wear a camlet robe, never to cut his beard or nails, nor ever to stray beyond the limits of the grounds. If he lived there, under all these restrictions, till the end of the term, he was to receive seven hundred guineas. But on breach of any of them, or if he quitted the place any time previous to that term, the whole was to be forfeited. One person attempted it, but a three weeks’ trial cured him.
