Chances are you are eagerly looking forward to the last day of school and nearly three months of free time.
Chances are also that you heard that this nice long summer vacation is somehow connected to the early years of the country when agriculture was the most important industry and kids had to help out on their farms during this time. If so, you heard wrong.
For starters, there wasn’t much to do on farms in the summer. The busy times were spring (planting) and fall (harvesting). As a result, most farm kids went to school during the summer and winter. At best they spent a total of six months learning the three Rs.
It was a very different situation in cities as the country became increasingly urbanized. Big-city kids might spend as much as 48 weeks in class, with a week off every 12 weeks. Since attendance wasn’t mandatory, though, they probably only attended school about as much as they do now.
But if so many kids were playing hooky, reformers said, why bother keeping schools open all year? Some doctors backed up the idea of closing for a period of time, saying that keeping kids cooped up for most of the year wasn’t good for their health.
So education officials decided to eliminate the summer quarter. The first reason was that schools were not air conditioned back then and almost unbearable during heat waves. Also, there was also a strong belief that summer was the time when epidemics of serious diseases such as polio got started. Many people thought having so many children packed so close to each other in classrooms helped spread the illnesses. Third, upper-class and middle-class families often took vacations during the hot months.
With increasing mechanization on farms and many farm families moving to the cities, helping with planting and harvesting wasn’t as important. Farm states added those spring and fall months to the school year and gave kids the summers off, just like big-city folk.
However, some research suggests that the “summer slide” causes students to lose an average of a month of learning. Students typically don’t do as well on tests in the fall—after the long summer break—than in the spring when they’ve been in school for several months. Most other developed countries spend more time in the classroom and generally do better on standardized testing. As a result of these factors, a few states are considering lengthening the school year from the current 180 days to 200.

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.

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.

This summer, you may be able to observe an amazing event in nature. You can watch a small animal build a structure much bigger than itself, using materials from inside its own body!
This is what happens when a spider spins a web. Inside a spider are glands that can produce seven different kinds of silk. The silk comes out of little spigots, called spinnerets, at the rear of the spider's body.
A strand of spider silk is stronger than a similar strand of steel, and spiders use this amazing material in many ways. If they catch an insect, they may wrap it in silk, to eat later. Female spiders enclose their eggs in a silken sac to protect them. And some spiders—almost always females—make webs that are death traps for insects.
Webs can be in the shape of funnels, sheets, or domes, but the best-known are called orb webs. From an orb web's center, lines of silk radiate out in all directions, like the spokes of a bicycle wheel. After building this basic structure, a spider goes round and round, laying down ever-bigger circles of silk. Some of the silk threads have sticky glue to catch a moth or other prey. A spider can create this whole complex design in an hour or less.
When an orb web is complete, some kinds of spiders wait right in the center. Others hide at an edge. Either way, the builder keeps a front leg in touch with the web. Vibrations from the threads tell a spider whether prey has been caught.
Spiders often have to repair their webs, and some species routinely build a new one every day. And they recycle! They eat most of their old web. After digestion, it becomes brand new silk for the next construction job.
You may be able to watch a spider on the job. Look for webs in a field, park, or backyard. Also look for webs near doors, windows, or on a porch. The nighttime lights from such places attract night-flying insects, and spiders often build webs there. They may or may not be orb webs, but watching any kind of spider at work on its silken insect-trap can be fascinating fun.
And remember: the spider wants nothing to do with you. It is just trying to stay safe and catch some food.

Have you ever noticed how photographs of underwater scenes have a bluish tint? Sunlight is made up of a rainbow of colors, but when it enters the water the reds and yellows in the light are quickly filtered out. The blues and greens penetrate deeper into the water and give those watery scenes their peculiar cast. Because there is very little red light in the deep sea, most of the animals that live there have never evolved the ability to see the color red. This is why many deep-sea animals are red. In the depths of the ocean, a creature that can’t be seen is safe from many predators.
There is an unusual fish that takes advantage of its fellow sea creatures’ colorblindness. The stoplight loosejaw, a member of the dragonfish family, can see the color red. Not only that, but it has a patch on its face that glows red. It also has a glowing green spot on its face, which is probably used to communicate with other dragonfish. These red and green patches explain the “stoplight” part of this fish’s name. The “loosejaw” comes from this fish’s ability to open its mouth extra wide and swallow large prey. Scientists think that the open structure of the lower jaw allows the fish to close its mouth quickly, making it difficult for prey to escape. Relative to its size, the stoplight loosejaw has one of the widest gapes of any fish, with a lower jaw measuring one-quarter of the fish’s length. It’s not easy for animals that live in the dark waters of the deep sea to find prey. Many of them, including the stoplight loosejaw, have large mouths and sharp fangs that help ensure that their prey cannot escape.
Below about 650 feet (200 meters), very little sunlight penetrates the ocean. Below 3,300 feet (1,000 meters), the only light is that produced by living creatures. Almost all deep-sea creatures can bioluminescence, or make their own light. But the light they produce is usually blue or green. When the stoplight loosejaw switches on its red spotlight, other creatures in the water are illuminated. Being blind to the color red, they don’t realize that they’ve been spotted. Dragonfish are not known as picky eaters. If one of the lit-up animals is a fish, shrimp, or other suitable prey, the stoplight loosejaw quickly grabs it and swallows it.
The stoplight loosejaw's attributes include a red spot, hinged jaws, and needle-like teeth. Illustration by Steve Jenkins
There are two kinds of stoplight loosejaws. The Northern (Malacosteus niger) shown here and the Southern. Together they are found everywhere in the world except the North and South Poles. Wikimedia Commons
