People have always had to find ways to keep food safe to eat. Methods to dry, smoke and salt food were invented thousands of years ago. The process of canning is much more recent. This storage method keeps food safe to eat for long periods of time. Today, canning is one of the most popular methods of storing food.

Canning uses heat to kill bacteria and other micro-organisms that cause poisons to form in food. Canning also takes away the air that these organisms need to live. One popular method of canning uses a water bath.

Clean fruits or vegetables are placed in glass bottles. The food can be put into the bottles either hot or cold. The cold method is used for soft fruits and vegetables that could lose their shape or taste. Firmer fruits and most vegetables are usually cooked. They take up less space in the bottles. After the food has been placed in glass bottles, boiling water is poured into the bottles to about three centimeters below the top. Then covers are placed on the bottles, but are not turned all the way. The bottles are placed in a large container filled with warm water that is then brought to a boil. The water must completely cover the bottles, from three to five centimeters over the top. When the water boils, any air in the bottles will be expelled. The boiling continues for several minutes. Then the bottles are allowed to cool. Finally, they are placed briefly into cold water. This makes a strong barrier to keep the air out. In other words, a vacuum is created. When the bottles are completely cool, notes can be placed on them to identify what is inside. The bottles can then be stored in a cool, dark place at a temperature of between four and twenty-one degrees Celsius.

Canning allows your family to enjoy foods that might not come fresh throughout the year. It is also a good way to store food for six months to a year, or even several years, in case of an emergency. It does not cost much to continue canning every year once the equipment has been purchased.

You can get more information about canning food from the group, Volunteers in Technical Assistance. VITA is on the Internet at vita.org.

Last Friday my brother and I were driving home together after doing some shopping and gave our attention to an interesting conversation. Because of this distraction (分心) my brother took a wrong turn.

Unfortunately, the wrong turn took us towards a bridge and we had no way to turn back. Unwillingly, my brother paid the bridge fee and drove on. He was clearly frustrated by the mistake and the needless waste of $4.

We eventually reached an exit and, as we took it, my brother noticed a young fellow pulled over to the side of the road. He came out of his car and tried to phone someone. I was busy trying to figure out which way we would go next but my brother pulled over and asked the guy if he needed any help. And he did. He had a flat tire and needed a tool to get it off.

My brother gave him a wrench（扳手）, and then began to help him change the flat. The young man said that this had been a bad week for him: earlier he had gotten into a minor car accident, and now this flat on his way home from work. But he called us “a breath of fresh air” and kept thanking us because he really would have been stuck if we hadn’t come along.

After we finished the job he thanked us again and pulled out $20 from his pocket and tried to give it to us. “No,” I said. “We were never supposed to even get on that bridge, we took a wrong turn. But now we know why we did. It was to help you. Thank you for turning our mistake into an opportunity to serve.”

What I loved most was that my brother was able to see a chance to help. His reaction in the situation is a lesson for everyone and we felt so good the rest of the day.

BROOKSVILLE — It’s the time of year again, when young bears are on their own for the first time. And that means more sightings where bears usually aren’t supposed to be.

This weekend, a 258-pound black bear took a brief tour of Brooksville, with police and firefighters chasing.

Another black bear, weighing just 100 pounds, was spotted Saturday, crossing busy U. S. 19 near a retirement community in Spring Hill. Several other bear reports have come from Citrus County.

"It is really difficult for the younger bears to find their own land around here, " said Niki Everitt, bear hot line director for the Gulf Coast Conservancy.

Brooksville’s bear first was spotted late Thursday crossing State Road 50, headed toward Tom Varn Park. Police and firefighters tracked the bear through the park and the Brooksville Quarry golf course.

The bear then wounded down the middle of Broad Street before being surrounded near Luigi’s Pizza. An official with the Florida Game and Fresh Water Fish Commission came with a tranquilizer spear(加入镇静剂的矛).planning to stick the bear by hand. "The guy saw the size of the bear and figured that wasn’t a great idea, "said Capt. Frank Phillips of the Brooksville Fire Department.

Emergency officials waited until a tranquilizer gun was brought from Land O’ Lakes. The bear then got a free ride to the Chassahowitzka Wildlife Management Area.

It is not unusual for bears to move into living areas this time of year, experts say. Mothers give their male baby bears the boot once the youngsters are 2 years old. With living areas growing, the young bears keep finding smaller and smaller areas in which they can set up their own land.

"They’ re trying to find a land of their own, where they won ‘t get beat up, " said Lt. Rip Stalvey, a game commission spokesman.

Everitt said people should not be too concerned about the recent bear sightings, since" we have never had a bear attack in Florida."

Black bears mainly eat the tender and fresh leaves of Sabal palms, as well as acorns and berries. Recent weeks of dry weather likely have reduced their food supply.

"If we don’t get some relief soon," Everitt said," we’re probably going to see a lot more of it."
