Q: "I can't see clearly, because I don't wear my glasses today." We always hear people saying something like this. Glasses are very important to many people. Do you know how they were invented and developed? Glasses took a long time to develop into what you can find in the glasses store today. The Chinese first used colored glasses as fashion. They thought that those glasses had magic, but they didn't think that glasses could help eyes to see clearly. In 1262, the inventor, Roger Bacon, discovered the amazing function of lenses , and he thought that glasses could be used to help people to see. Twenty years later, in Florence, Italy, the inventor, Alessandro di Spina, made the first pair of glasses that could help people to see. Although these glasses worked, scientists didn't understand how glasses helped eyes to see. They thought that eyes sent out light onto whatever a person was looking at, and then the light came back to the eyes. Johannes Kepler finally found out how glasses worked. Inventors continued to improve glasses. In 1784, Ben Franklin created glasses that had bifocal lenses. Many years later, in 1827, George Airy made circle-shaped glasses to correct _ , an eye problem that stops the eyes from seeing things clearly.

Q: CHAPTER XX

A LONG CHASE BEGUN

As they journeyed down the Hudson the boys and Martin Harris scanned the river eagerly for some sign of the _Flyaway_.

"It's ten to one she put down a pretty good distance," remarked Dick. "They wouldn't bring Dora over here unless they were bound for New York or some other place as far or further."

"I believe you," said Tom. "But she may be delayed, and if what Harris says is true the _Searchlight_ ought to make better time than Baxter's craft."

Several miles were covered, when, Sam, who had just come up from the cabin, called attention to a farmer who was ferrying a load of hay across the river.

"If he's been at that sort of work all day he may know something of the _Flyaway_," he suggested.

"We'll hail him, anyway," said Tom. "It won't do any harm, providing we don't lose any time."

So the farmer was hailed and asked if he had seen anything of the craft.

"Waal now, I jest guess I did," he replied. "They war havin' great times on board of her--a takin' care of that crazy gal."

"A crazy girl!" cried Dick. "Who said she was crazy?"

"One of the young men. He said she was his sister and had escaped from some asylum. She called to me to help her. But I don't want nuthin' to do with crazy gals. My wife's cousin was out of his head and he cut up high jinks around the house, a-threatenin' folks with a butcher knife."

Q: (CNN) -- Sri Lankan cricketers have described for the first time how they feared some of their teammates had been killed during a deadly attack on the team bus by gunmen in Pakistan -- and paid tribute to the driver of the bus for saving their lives.

Thilan Samaraweera is due to undergo surgery to have a bullet removed from his leg.

Six police officers and a driver were killed in the ambush by around a dozen attackers armed with automatic weapons as the players made their way to Lahore's cricket stadium early Tuesday.

Two players, Tharanga Paranavitana and Thilan Samaraweera, suffered gunshot wounds to the chest and leg respectively while six others suffered shrapnel wounds. But vice-captain Kumar Sangakkara told CNN he believed Paranavitana had been killed when he collapsed after being shot.

"I was lying on the ground. I heard Thilan (Samaraweera) groan and I heard Tharanga Paranavitana say something. I turned around and a bullet whizzed past my head and hit the seat in front of me. And then I got hit in the shoulder by shrapnel," Sangakkara said.

"Then I saw Tharanga Paranavitana get up and say 'I've been shot' and then he collapsed on the seat. I really thought he was seriously hurt or even dead." Read profiles of the wounded players "

Describing the initial moments of the ambush, Sri Lanka coach Trevor Bayliss said there had been an explosion "which someone said later was a rocket launcher that missed the bus and went over the top and hit somewhere in front of us." Watch footage of the gunmen staging their attack "
