A man once said how useless it was to put advertisements in the newspapers. "Last week," said he, "my umbrella was stolen from a London church. As it was a present ,I spent twice its worth in advertising, but I didn't get it back."
"How did you write your advertisement?" asked one of the listeners, a merchant. "Here it is," said the man, taking out of his pocket a slip cut from a newspaper. The other man took it and read, "Lost from the City Church last Sunday evening, a black silk umbrella. The gentleman who finds it will receive ten shillings on leaving it at No. 10 Broad Street."
"Now," said the merchant, "I often advertise, and find that it pays me well. But the way in which an advertisement is expressed is of extreme importance. Let us try for your umbrella again, and if it fails, I'll buy you a new one."
The merchant then took a slip of paper out of his pocket and wrote:" If the man who was seen to take an umbrella from the City Church last Sunday evening doesn't wish to get into trouble, he will return the umbrella to No. 10 Broad Street. He is well known."
This appeared in the paper, and on the following morning, the man was astonished when he opened the front door. In the doorway lay at least twelve umbrellas of all sizes and colors that had been thrown in, and his own was among the number. Many of them had notes fastened to them saying that they had been taken by mistake, and begging the loser mot to say anything about the matter.

In June 1979, Bryan Allen, a biologist from California who is also a hang-gliding enthusiast and an amateur racing cyclist, made history by pedaling across the English Channel in the Gossamer Albatross, a super-light, propeller-driven aircraft invented by Dr. Paul McCready.
The Gossamer Albatross, a 33-kilogram (72-pound) aircraft with a polythene-covered fuselage and a wingspan of 30 meter (100 feet ), the same as that of a DC-9 jet airliner, was driven mostly by conventional bicycle components. Allen sat on a bicycle saddle inside the transparent fuselage and pedaled a bicycle crank and chain-wheel that turned a special urethane chain geared through two more chain-wheels to a propeller mounted aft of the wing.
Shortly after dawn that June day, the Albatross rolled down a harbored runway in Folkstone, England. Pedaling hard, Allen got the aircraft aloft and churned his way toward France. After almost three hours of pedaling to produce a constant output of about 0.3 horsepower , he landed on a beach near Calais, the first person to fly a human-powered craft across the Channel. Allen and an American team led by Dr. McCready were awarded the '100,000 prize by Henry Kremer, a British industrialist, for the first successful nonstop human-powered flight across the English Channel.
Allen and McCready were no strangers to human-power flight. They and the American team had previously won the '25,000 Kremer prize for the first such sustained flight when they had successfully flown a one-mile figure-eight course in McCready's Gossamer Condor.
