Bug Hunt
Frustrated in catching insects in 1904, Max Terletzky hit on this rather alarming solution. A basket with an open mouth is attached to the business end of a feathered arrow; the prospective bug hunter props open the basket’s mouth, stalks his prey, and fires at it using a bow. The arrow is attached to a cord in the archer’s hand, which closes the basket doors when the arrow has intercepted the bug and reached the limit of its flight. At that point the arrow drops to the ground and the archer can draw in the cord and claim his prize.
Terletzky writes, “This particular construction of the automatic device for closing the doors of the basket is extremely strong, simple, and durable in construction, as well as thoroughly efficient in operation.” For all I know he’s right.
A Puzzling Exit
Canadian doctor Samuel Bean created a curious tombstone for his first two wives, Henrietta and Susanna, who died in succession in the 1860s and are buried side by side in Rushes Cemetery near Crosshill, Wellesley Township, Ontario. The original stone weathered badly and was replaced with this durable granite replica in 1982. What does it say?
Asking Directions
You’re a logician who wants to know which of two roads leads to a village. Standing nearby, inevitably, are three natives: one always lies, one always tells the truth, and one answers randomly. You don’t know which is which, and you can ask only two yes-or-no questions, each directed to a single native. How can you get the information you need?
The Thunder Stone

In Saint Petersburg, an equestrian statue of Peter the Great stands atop an enormous pedestal of granite. The statue was conceived by French sculptor Étienne Maurice Falconet, who envisioned the horse rearing at the edge of a great cliff under Peter’s restraining hand.
Casting the horse and rider was relatively easy; harder was finding a portable cliff. In September 1768 a peasant led authorities to an enormous boulder half-buried near the village of Konnaia, four miles north of the Gulf of Finland and about 13 miles from the center of Saint Petersburg. Falconet proposed cutting it into pieces, but Catherine the Great, who wanted to show off Russia’s technological potential, ordered it moved whole, “first by land and then by water.”
Incredibly, she got her wish. The unearthed boulder measured 42 feet long, 27 feet wide, and 21 feet high; even when trimmed by a third it weighed an estimated 3 million pounds. But it was mounted on a chassis and rolled along atop large copper ball bearings, a “mountain on eggs,” as stonecutters worked continuously to shape it. When they reached the Gulf of Finland it was transferred precariously to a barge mounted between two cutters of the imperial navy, which carried it carefully to the pier at Senate Square, where it was installed in 1770, after two years of work. The finished pedestal stands 21 feet tall.
“The daring of this enterprise has no parallel among the Egyptians and the Romans,” marveled the Journal Encyclopédique; the English traveler John Carr said that the feat astonished “every beholder with a stupendous evidence of toil and enterprise, unparalleled since the subversion of the Roman empire.” It remains the largest stone ever moved by man.
A Dark Day
On Oct. 21, 1966, an avalanche of mining debris descended into the Welsh mining village of Aberfan, filling the classrooms of a local junior school with mud and killing 144 people, 116 of them children. In response to a subsequent newspaper appeal, Shrewsbury psychiatrist J.C. Barker received 76 letters from people who claimed to have had precognition of the event. Of these, 22 were supported by witnesses. This account, by the parents of 10-year-old Eryl Mai Jones, was compiled by a local minister and signed by them as correct:
She was an attractive dependable child, not given to imagination. A fortnight before the disaster she said to her mother, who at the time was putting some money aside for her, ‘Mummy, I’m not afraid to die.’ Her mother replied, ‘Why do you talk of dying, and you so young; do you want a lollipop?’ ‘No,’ she said, ‘But I shall be with Peter and June’ (schoolmates). The day before the disaster she said to her mother, ‘Mummy, let me tell you about my dream last night.’ Her mother answered gently, ‘Darling, I’ve no time now. Tell me again later.’ The child replied, ‘No, Mummy, you must listen. I dreamt I went to school and there was no school there. Something black had come down all over it.’ Her mother answered, ‘You mustn’t have chips for supper for a bit.’ The next day off to school went her daughter as happy as ever. In the communal grave she was buried with Peter on one side and June on the other.
“This last point may not, however, be significant, since the order of burial was apparently influenced by parents’ requests.”

House Calls
William … asks me to set down the story of Barbara Wilkinson’s Turtle Dove. Barbara is an old maid. She had 2 turtle Doves. One of them died the first year I think. The other bird continued to live alone in its cage for 9 years, but for one whole year it had a companion and daily visitor, a little mouse that used to come and feed with it, and the Dove would caress it, and cower over it with its wings, and make a loving noise to it. The mouse though it did not testify equal delight in the Dove’s company yet it was at perfect ease. The poor mouse disappeared and the Dove was left solitary till its death. It died of a short sickness and was buried under a tree with funeral ceremony by Barbara and her maiden, and one or two others.

All Right Then
W.H. Auden won first prize for mathematics at St. Edmund’s School in Hindhead, Surrey, when he was 13. He recalled being asked to learn the following mnemonic around 1919:
Minus times Minus equals Plus;
The reason for this we need not discuss.
