Because it is Memorial Day, there will be no post. Tomorrow Cheryl Harness will give us some details about George Washington Carver we may not have known before.
Did you know that George Washington Carver, the famous African American scientist, used to live in a little sod house on the prairie? Well, he did. And did you know that he built it himself? He did that too, out in windy western Kansas.
Since he was 13 or so, Missouri-born George had been on his own. He did laundry to earn his keep while he lived in different families’ spare rooms and went to any school that would accept a brilliant, curious, black boy. Such schools were hard to find in the early 1880s. He applied to and got accepted to one Kansas college only to be turned away when the professors saw his dark skin. So he used his savings to buy some chickens and a half-mile square of land (160 acres) out near the tiny town of Beeler, KS, in the spring of 1886.
His chickens were probably very happy with all the wiggly critters that appeared as 22-year-old George started sodbusting with tools he borrowed from his prairie neighbors. By that I mean he cut and dug up blocks of sod, topsoil plus grass roots. He lined up and stacked these heavy, earthen building blocks until he had his own soddy, a thick-walled sod cabin, 14 feet square. Out on the prairies, there weren’t many trees for wooden houses, but thin willows grew along the creeks. With willow poles, dry grass, and sod slabs, George could make a roof.
He planted little trees plus corn and other vegetables and on Sundays, he went to church and sang hymns with his neighbors. George was very musical, with a fine, high tenor voice.
With their thick walls, soddies were cool in the summer and warm in the winter, but nobody was prepared for the winter that began in 1887. On January 12, 1888, the weather was balmy, but then the temperature dropped like an anvil and a truly epic blizzard began. When the snow quit falling and the winds quit howling, nearly 500 people and thousands of cattle were frozen and dead out on America’s Great Plains! George survived in his little cabin, but that was enough prairie life for him. He headed east, away from the frontier, and, at last, got what he’d wanted all along, a proper education. George Washington Carver became the very first black graduate of the college known these days as Iowa State University.
The multitalented hand of Cheryl Harness creates another winning combination of history, biography, and illustration: the inspiring story of a man who rose from slavery to worldwide fame as America’s Plant Doctor. Cheryl Harness’ lively narrative follows Carver’s rise to international fame: our hero dines at the White House, works with Henry Ford, and testifies to Congress. The book’s vivid illustrations are an invitation to step back in time and become an active participant in this compelling story. For more information, click here.
Rumor had it that the Brooklyn Bridge might not be safe and people were hurt and killed in the ensuing panic. But P. T. Barnum, the famous circus man, had an idea to prove the bridge's safety and, of course, get himself a bit of publicity. Jan Adkins will fill in the details tomorrow.
The Explainer General
On May 24, 1883, The Brooklyn Bridge was opened to the public. It took 14 years, $15 million and many lives to link Brooklyn and Manhattan.
Before work was begun, its designer, John A. Roebling, was making final surveys of the site. A docking ferryboat nudged a piling near him, driving a dirty nail into his foot. He died of tetanus 24 days later. His son, Washington Roebling took over the engineering project.
To sink the bridge tower foundations down to bedrock, workers excavated river silt inside two open-bottomed 3000 ton iron bases, caissons. High -pressure air pumps kept river water out. As the caissons were dug deeper beneath the river surface, air pressure grew higher; work became more dangerous. When they were digging near seventy feet deep, a few workers walked through the caisson air-lock at the surface, across the street to the tavern, and dropped down dead. The cause: nitrogen embolism—gas dissolved in blood under high pressure expanding rapidly at normal pressure. Scuba divers call it “the bends.” Washington Roebling, himself, was crippled this way but monitored the project through a telescope from his bed upriver. His brilliant wife, Emily Warren Roebling, managed construction on-site. Twenty to 30 bridge workers were killed in construction from nitrogen embolism, being struck by falling material, and by falls from the towers.
It was the longest suspension bridge in the world, with a river-span of 1595.5 feet. Anyone could cross: 1¢ for a pedestrian, 5¢ for a horse and rider, 10¢ for a horse and wagon, 5¢ for cows, 2¢ for sheep or hogs.
Only six days after its opening, the bridge was crowded with walkers when a rumor started that the bridge was collapsing! Strollers stampeded, killing 12, injuring 35 in the panic. Was the great bridge safe?
Months later, May 17, 1884, the great huckster and self-promoter P. T. Barnum set out to prove the solidity of the bridge “in the interest of the dear public.” Across the broad bridge paraded 21 elephants with Barnum’s famous African elephant Jumbo in the rear. They were followed by seven Bactrian camels (two-hump) and ten dromedaries (one-hump). Since elephant and camel fares had never been specified, no tolls were paid. The New York Times reported “…it seemed as if Noah’s Ark were emptying itself over on Long Island.”
If any doubts remained, Barnum’s ballyhoo proof put them to rest.
The story of how Jumbo was brought from Africa to the United States is a fascinating one -- Google it. In the meantime, you might want to have a look at Jan Adkin's fascinating description of how people often have to use brains rather than brawn to move heavy items.

You know how many years you've lived and you can probably figure out how many months or weeks with some simple math. But figuring out how many seconds you've lived is a bit more challenging, but math guru David Schwartz will give you a hand with the calculations tomorrow.

The amazing, engaging, math exponent
Do you want to be a lot older? Here’s how: state your age in seconds instead of years!
Ready to do some math? But what math will you do?
First you have to design a problem-solving strategy. There are many approaches but for all of them, consider that with every passing second, you are a second older. So your age is a moving target. Best to pick a specific time of day and find your age in seconds at that time today.
It doesn’t really matter what time of day you pick. If you can find out from your birth certificate what time of day you were born, you could select that time today for your target. If you were born at 4:14pm, you will find out how old you are (in seconds) at 4:14pm today.
Or just pick any time today and pretend you were born at that time.
What next? I hope you will try out your own approach but here is a simple strategy that would work:
Step 1. How many days old are you? Figure out how many days elapsed between the day you were born and your most recent birthday. There are 365 days in a year, not counting leap years. In your lifetime, every year divisible by 4 was a leap year and it had a 366th day, which was February 29th. So add an extra day for each February 29th you’ve lived through.
Then figure out how many days have passed since your last birthday. Try to find a way to make this job quicker than counting each day. Look at calendars as you do this to find shortcuts.
Now you have your age in days. It’s already looking like a big number, isn’t it? Just wait!
Step 2. How many seconds are in a day? Think about how to figure this out. You know how many seconds are in a minute (60) and how many minutes are in an hour (60) and how many hours are in a day (24). So how many seconds are in a day? Multiply 60 X 60 X 24. Bet you didn’t realize a day was so long!
Step 3 So what’s Step 3? You now know how many days you have lived and how many seconds are in a day, so what do you do next? Again, multiply!
Next time someone tells you you’re not old enough to do something, you can tell him or her, “Oh yes I am. I’m 299,592,620. That’s what I was at 11:30 this morning. Now I’m even older!”
Good luck with that!

Teaching the Power of Wonder
So what’s a knot garden?
Knot gardens first caught my eye when I was a kid and visited Mount Vernon, the home of George Washington. When I later visited England, I saw how our first president had carried on a long-standing tradition. Knot gardens, edged with tight growing shrubs like boxwood, wound across the property of kings and queens and lords and ladies.
Sometimes herbs or flowers were planted inside the rows of shrubs, which twist and turn to form shapes that look like fancy knots. England’s Queen Elizabeth I enjoyed strolling through such gardens with her ladies-in-waiting. Certainly the queen’s knot gardens were among the finest in her day.
In Washington DC, we Americans have a knot garden inside our National Arboretum, an outdoor museum of plants and trees. Small evergreens form the knot. Visitors stop to sniff the fragrant herbs planted both inside and outside the knot of evergreens.
It can take years to establish a knot garden, but you can create an updated version that will grow in just one summer. All it takes is a little space, a variety of marigold plants, a digging tool, a bit of water-soluble fertilizer, and regular care.
Plan your garden to be three feet by three feet. Look at knot gardens online for clues and make a simple design. Marigolds come in many colors, sizes, and shapes. Think about how tall and wide they’ll grow. Do you want tall flowers in the corners?
Now plant your plants. Carefully pop the flowers from their packs and transplant them into roomy holes so they’ll grow well. Plant the inside garden first. Then move to the outside. At first your garden might look skimpy, but in a few weeks it will fill in.
Mix fertilizer with water in your watering can and give the little plants a good drink. Marigolds are heavy feeders needing regular watering and fertilizer. Every few days, stick your fingers in the dirt to check for moisture. When the soil’s getting dry, it’s time to water— early in the morning or late in the day.
