　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 wound 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 (加入镇静的剂的矛), 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.”

　The vitamins necessary for a healthy body are normally supplied by a good mixed diet, including a variety of fruits and green vegetables. It is only when people try to live on a very restricted diet, say that when trying to lose weight, that it is necessary to make special provisions to supply the missing vitamins.

　An example of the dangers of a restricted diet may be seen in the disease known as “beri-beri”,which used to make large numbers of Eastern people who lived mainly on rice suffer. In the early years of last century, a Dutch scientist named Eijkman was trying to discover the cause of beri-beri. At first he thought it was transmitted by a germ. He was working in a Japanese hospital, where the patients were fed on polished rice which had had the outer coverings removed from the grain, it was thought this would be easier for weak and sick people to digest.

　Eijkman thought his germ theory was proved when he noticed the chickens in the hospital yard, which were fed on remains from the patients’plates, were also showing signs of the disease. He then tried to separate the germ, which he thought was causing the disease, but his experiments were interrupted by a hospital official, who ordered that the rice without coverings, even though left over by the patients, was too good for chickens. It should be recooked for the patients, and the chickens should be fed on cheap, rough rice with the outer coverings still on the grain.

　Eijkman noticed that the chickens began to recover on the new diet. He began to consider the possibility that eating unmilled rice(糙米)somehow prevented or cured beri-beri - even that a lack of some ingredient(成分)in the coverings may be the cause of the disease. Indeed this was the case. The element needed to prevent beri-beri was shortly afterwards separated from rice coverings and is now known as vitamin B. The milled rice, though more expensive, was in fact causing the disease the hospital was trying to cure. Nowadays, this terrible disease is much less common thanks to our knowledge of vitamins.

　Children are our future, and it’s up to us to arm them with the tools to succeed. Sadly, today’s children are being armed with more dangerous toolslike weapons, drugs and gangs. Once a relatively peaceful environment, many schoolyards of today are becoming unsafe for both students and teachers.

　Home schools are available to give you choices. Home schooling provides top-quality education, flexibility, and freedom to create your own schedule. At Heritage Home School we believe the choice should be yours.

　Thanks in part to modern technology, home schooling information is becoming readily available across our nation. A recent study by the ITBS (Iowa Tests of Basic Skills) and TAP (Tests of Achievement and Proficiency) shows us that students of home schools do particularly well when compared with the nationwide average. In every subject at every grade level, students of home schooling scored obviously higher than those in public and private schools.

　If you’re new to home schooling, you may be asking yourself, “Will home schools really work for my children?”

　Fact: A nationwide study using a random(任意)selection of 1,516 families found students of home schooling to be scoring, on average, at or above the 80th percentile in all areas on standardized achievement test.

　Note: The national average on standardized achievement tests is the 50th percentile.

　Collectively, the staff at Heritage Home School brings 65 years of experience in home schooling curriculum. We’ve placed students in the top 2 % of the nation in math and many are successfully moving on to college.

　One study found that of the home schooled adults, 0% were unemployed, 0% were on welfare and 94% said home education prepared them to be independent persons.
