The Explainer General
Gigantic earthquakes rocked the Midwestern United States between December 16, 1811, and February 7, 1812. A fault in our continent’s stone base runs beneath the Mississippi River near what is now New Madrid, Missouri. Unequal pressures built up on both sides of this fault and the sides slipped to ease the pressure. Whammo—the first of 3 earthquakes from these slips was felt as far away as New York City, Washington, DC, and Charleston, South Carolina.
There were no scientific instruments to measure the New Madrid Quakes in 1812 so geologists have sifted through widespread accounts from old journals and newspapers for data. Putting the accounts together on a map, we know the quakes were felt over an area of 1,930,000 square miles. They earthquakes began with a pair of terrific shocks at 2:15 and 7:15 local time on the morning of December 16, 1811, both measuring 7.2 - 8.1 on the Richter scale. They were followed by a 7.0 - 7.8 quake on January 23, 1812, and a 7.4 - 8.0 event on February 7, 1912.
The quakes were violent, earth-shifting events. There have been even more powerful earthquakes in Alaska and Hawaii, both vulnerable to deep geological pressures, But the New Madrid quakes are the largest to ever occur in the original forty-eight states. Yet little damage or loss of life was reported. The region was then part of Louisiana Territory, sparsely inhabited with small villages and only a few multi-story masonry buildings. We can’t know how many log cabins or small home chimneys were thrown down, or how many Native Americans were affected.
Coincidentally, the first steam paddle-wheeler on the Mississippi, the New Orleans, invented by Robert Fulton, was making its first trip south during the quakes. Land heaves caused massive waves to travel up and down the river. When the little southbound New Orleans met one of these waves it seemed that the great Mississippi was running backward. Some land rose, riverbanks crumbled, some land subsided and formed new lakes. The river’s course was so changed that maps were useless, and the steamboat did a remarkable job of “feeling its way” through the new channels to dock at New Orleans on January 10, 1812.
We’ve come to expect earthquake and volcanic activity around the Pacific “Ring of Fire,” and other hot-spots of geologic shift, but the New Madrid Quake was the product of an unexpected fault in earth’s crust we now call the New Madrid Seismic Zone. And, yes, there is the possibility of similar earthquakes from this zone in the future. The Earth that seems so solid is secretly restless.

“It is at these times you realize the blessing of a good, thick skirt,” said Mary Kingsley after she crashed into a cleverly concealed leopard pit lined with twelve-inch ivory spikes.
The year was 1895, the place Equatorial West Africa, and the spunky lady saved, thanks to her observance to the dress code of the day, was a young Englishwoman collecting species of fish and beetles for the British Museum.
Mary Kingsley was the daughter of a physician who spent most of his time traveling. Although she received no formal education (reserved for her brother Charles), Mary learned to read, becoming fascinated with subjects such as science, exploration and piracy.
At one point she was granted permission to teach herself German, but only after she could iron a shirt properly. Mary learned chemistry, experimented with gunpowder and electricity, and became engrossed by the intricacies of plumbing. After years of caring for her invalid mother, in 1892 both her parents died. With the small inheritance left to her came the fulfillment of a dream: to explore West Africa.
When Mary crashed into the leopard pit, she was traveling in what was then the French Congo, getting to know the Fangs, reportedly a tribe of cannibals. Traveling by canoe, she was once marooned in a crocodile-infested lagoon. When one tried to climb aboard, she was there with a paddle, ready to “fetch him a clip on the snout.”
After two trips, she wrote a book called Travels in West Africa. She became a sought-after lecturer and celebrity. In public appearances she was both funny and serious, peppering her narrative with jokes, often at her own expense, but also being critical of the way the British had steamrolled into the African continent, with little regard for its ancient cultures.
In 1900 she sailed to Africa for the third time, responding to an urgent call for nurses in South Africa, where war was underway. Assigned to a hospital where hundreds of soldiers were dying from a raging epidemic, she became ill herself, and died two months later. She was buried at sea with military honor.
In her book, she remembers: “Indeed, much as I have enjoyed life in Africa, I do not think I ever enjoyed it to the full as I did when dropping down the Rembwe… Ah me! Give me a West African river and a canoe for sheer pleasure.”
Rave reviews for Roxie Munro's book Market Maze:
"A great way to introduce kids to their foods' origins and to prepare them for a greenmarket visit of their own." Kirkus (Starred review!) excerpt.
"From a parent’s or teacher’s point of view, here’s a good way for kids to gain the visual discrimination skills needed for reading, while they learn about the sources of food at their local farmers’ markets. For kids, though, the combination of mazes and hidden objects is just plain fun. It’s a winning combination." Booklist review excerpt.

The Renaissance began in Europe in the 15th century and marked the change from the medieval period to the modern world. Towering figures such as Michelangelo, Galileo, and especially Leonardo da Vinci were known as Renaissance men because of their talents and lasting achievements in several important areas of knowledge. They were also accomplished musicians, public speakers, athletes, poets, and so forth. And they were expected to do all this stuff without breaking a sweat.
You could give the same title to an ancient Egyptian named Imhotep, who lived about 2600 BCE. He was the vizier, the most important government official, during the reign of Pharaoh Djoser. He served as the high priest of the god Ra and was an expert astronomer.
Imhotep designed and oversaw the building of the first major pyramid in Egypt. Located at Saqqara, at the time it was the world’s tallest structure. He innovated the use of stones rather than mud bricks to build it, and it was that added strength that enabled the pyramid to rise so high. He is also credited with the invention of several devices that facilitated the construction.
Many people believe that Imhotep, rather than the Greek Hippocrates who lived more than 2,000 years later, is the real “Father of Medicine.” In an era when most physicians relied on magic spells and appeals to the gods, Imhotep prescribed dozens of effective down-to-earth treatments for illnesses and injuries.
He is credited with ending a seven-year famine in Egypt. He advised the pharaoh to make sacrifices to Khnum, the god of the annual flooding of the Nile River, and thereby provide desperately needed water to farmers. On a more practical level, he invented an improved irrigation system to carry water to the crops even if the river level was abnormally low.
In addition to these accomplishments, an inscription at the base of one of his statues notes that he was “Chief Carpenter, Chief Sculptor, and Maker of Vases in Chief.” In his little spare time, he wrote poetry and dispensed philosophical advice.
Imhotep can also boast of two accomplishments that eluded even Leonardo da Vinci. He was deified after his death and worshipped for many centuries, an honor accorded to hardly anyone besides the pharaohs. And today the comic book community gives him the credit for founding S.H.I.E.L.D., the Marvel Comics espionage and crime-fighting agency that became the basis for blockbuster movies such as Iron Man, Thor, and Captain America.
Jim Whiting has written a book on another great Egyptian leader -- Ramses the Great who lived about 1350 years after Imhotep. He fully lived up to the "Great" part of his name. His reign lasted for 67 years, the second longest in Egypt’s 3,000-year history. He had dozens of wives and more than 100 children, outliving many of them. He was a military leader who expanded the borders of his country. That resulted in decades of peace and prosperity for his people. He ordered huge statues of himself to be erected all over Egypt.

Incoming shell! Whenever ten-year-old Lucy McRae heard that distinctive sound, she froze, allowing the explosive to fly on over her. Then she hurried into the safety of the family’s cave.
It was 1863 and Vicksburg, Mississippi, was being bombarded by Union artillery. It was located strategically on the Mississippi River. All along the waterfront, Confederate cannon prevented Union ships from taking control of the river and using it to invade the South. President Lincoln said that for the North to win the war, those cannons must be silenced. He selected General Ulysses Grant to force Vicksburg to surrender.
Grant’s army sieged the city of 5,000, cutting off food supplies and fresh water. Then he rained shells day and night on the Confederate troops defending Vicksburg and on its terrified civilians. But townspeople had no intention of giving up. Most of their men were off fighting, but those remaining were stalwart: there would be no surrender.
Instead, they dug more than 500 caves into the sides of Vicksburg’s many hills, where they took refuge. Everyone lived side by side, rich and poor, masters and slaves. Cooking tents were set up outside the entrances, and during lulls in shelling, residents hastily prepared whatever food they had. Lucy always stayed outside until the moment shelling started again.
The caves were hot, dark, dank, and crowded, and were home to spiders, scorpions, lizards, mosquitoes, and snakes. “It was living like tree roots,” one woman said. People brought in rugs, bedding, books and favorite artwork to make their surroundings more tolerable. Sometimes there were close calls when a shell hit a cave. Once Lucy was buried under a mound of sliding dirt for several minutes. When her frantic mother pulled her out, she gasped for air, her mouth and nose full of dirt.
Although the town was severely damaged by the shelling, because of the caves only a dozen people died in the forty-seven-day siege. Townspeople wanted to hold out, but daily rations of water and food were almost gone, forcing the city’ surrender on July 4, 1863.
The South’s loss of Vicksburg helped the North win the war. But the bravery of townspeople like Lucy, who held fast in the face of overwhelming odds, was never in dispute.

The onset of spring, summer, fall, and winter every year is precisely measured, depending on the sun’s position. But there’s no similar astronomical or scientific reason for celebrating New Years on January 1.
Many people don’t. The Chinese New Year occurs on the second new moon after the winter solstice, between late January and mid-February. Muslims mark the occasion on the first day of Muharram, the first month of the Islamic calendar. That calendar is based on the lunar cycle, 11 or 12 days shorter than the solar calendar. So their New Year comes a little earlier every year. Rosh Hashanah, the start of the Jewish New Year, is a two-day observance that begins 163 days after Passover and varies between September 5 and October 5. Unlike other New Year’s celebrations, Rosh Hashanah is holy, a time for piety rather than parties.
There was just as much variation in ancient times. In Babylon, the first new moon after the vernal equinox marked the New Year. Egyptians celebrated it in early August, when the annual Nile River flooding began. In Greece, Athens and Sparta couldn’t get along, so their respective new years didn’t occur at the same time. In Athens, it was the first new moon after the summer solstice, while the Spartans waited until early fall.
So how did January 1 become the most widely accepted start of the New Year? The answer: Julius Caesar. For centuries, the Roman calendar was in a state of chaos, with the number of days in the year fluctuating widely. In 46 BCE, Caesar worked with the brightest Egyptian astronomers to retool the calendar. He wanted the year to begin on the first of January, a month named after the god Janus. Janus had two faces: one looking backward (at the year just ending) and the other facing forward. For the Romans, it was party time!
Caesar didn’t stick around very long after his innovation. On the Ides of March—March 15, 44 BCE—he went to the Roman Senate as usual. While one senator distracted him, others swarmed around him with knives they’d hidden inside their togas, hacking and gashing. He collapsed and died.
His calendar proved more durable. When Roman legions conquered new territories, the natives had to adopt the Roman calendar. Every day, especially at the start of the new year, it was a reminder of Roman power.
