First successful steamboat

In 1783, the first successful steamboat, the Pyroscaphe, made a trial run on the River Saône in France. It was invented by a Frenchman, the Marquee Claude de Jouffroy d'Abbans. His earlier steam-powered boat tested in 1778 on the river Doubs used a Newcomen steam engine driving a hinged flap he modelled after the webbed feet of an aquatic bird, which was unsuccessful. He then built on ideas from James Watt's inventions to design a parallel-motion double-acting steam engine to drive a pair of large paddle wheels on the Pyroscaphe. Several thousand people viewed its trial, a 15 minute journey upstream on the River Saône. (Montgolfier's first balloon demonstration took place a few weeks earlier on 4 Jun 1783.)«

Advice From a Wise Woman

Sally was driving home from one of her business trips in Northern Arizona when she saw an Elderly Native American Woman walking on the side of the road.
As the trip was a long and quiet one, she stopped the car and asked the woman if she would like a ride. With a silent nod of thanks, the woman got into the car.
Resuming the journey, Sally tried in vain to make a bit of small talk with the woman.
The old woman just sat silently, looking intently at everything she saw, studying every little detail, until she noticed a brown bag on the seat next to Sally.
‘What in bag?’ asked the old woman. Sally looked down at the brown bag and said, ‘It’s a bottle of wine. I got it for my husband.’
The woman was silent for another moment or two.
Then, speaking with the quiet wisdom of an elder, she said, ‘Good trade.’
