input: Make use of the article to answer the questions. Edmund Halley was an English scientist who lived over 200 years ago. He studied the observations of comets which other scientists had made. The orbit of one particular comet was a very difficult mathematical problem. He could not figure it out. Neither could other scientists who dealt with such problems.

However, Halley had a friend named Isaac Newton, who was a brilliant mathematician. Newton thought he had already worked out that problem, but he could not find the papers on which he had done it. He told Halley that the orbit of a comet had the shape of an ellipse .

Now Halley set to work. He figured out(,)the orbits of some of the comets that had been observed by scientists. He made a surprising discovery. The comets that had appeared in the years 1531, 1607, and 1682 all had the same orbit. Yet their appearance had been 75 to 76 years apart.

This seemed very strange to Halley. Three different comets followed the same orbit. The more Halley thought about it, the more he thought that there had not been three different comets as people thought. He decided that they had simply seen the same comet three times. The comet had gone away and had come back again.

It was an astonishing idea! Halley felt certain to make a prediction of what would happen in the future. He decided that this would appear in the year 1758. There were 53 years to go before Halley's prediction could be tested. In 1758 the comet appeared in the sky. Halley did not see it, for he had died some years before. Ever since then that comet had been called Halley's comet, in his honor. 1. Who is the article about?

When Roy, the manager, had to leave for a few days, he put Rogers in charge. "What if the workers refuse to follow my orders?" Rogers asked. He thought of Tony, a worker who was always giving the other men a hard time. "Fire them," Roy said. Then, as if reading Rogers' mind, he added, "I suppose you want to fire Tony if you get the chance. I'd feel bad about that. Tony is the most reliable worker I've ever had. I know he complains a lot, but he comes first and leaves last. There has not been an accident on the hill where he works for eight years."

Rogers took over the manager's job the next day. He went to Tony and spoke to him, "Tony, did you know that I'm in charge today?" Tony didn't show any respect or interest. "I was going to fire you because you once gave me a hard time, but I want you to know I'm not," he told Tony, adding what Roy had said. When Rogers finished, tears streamed down Tony's face. That day Tony worked harder than ever before --and he smiled for the first time! Rogers went back to school after that summer.

Twelve years later he met Tony again. He was in charge of one of the largest logging companies in the West. Rogers asked him how he managed to become so successful. Tony replied, "If it were not for that time you spoke to me back in Idaho, I would not be myself today. That one minute changed my whole life."

HOLIDAYS AT THE FARM

Almost before they knew it, the mid-winter holidays were at hand, and the Rover boys went home to enjoy Christmas and New Year. On their way they stopped at several stores in Ithaca, where they purchased a number of Christmas presents. Some of these they mailed at the post-office. Dick sent a nice book to Dora, and Tom and Sam sent books to Grace and Nellie. The boys also united in the gift of a stick pin to Mrs. Stanhope and another to Mrs. Laning, and sent Mr. Laning a necktie. Captain Putnam was not forgotten, and they likewise remembered George Strong. The rest of their purchases they took home, for distribution there.

A number of the other students had come as far as Ithaca with them, and here the crowd had dinner at one of the hotels,--the same place where Tom had once played his great joke on Josiah Crabtree.

"By the way, who knows anything about Nick Pell?" asked one of the students, while dining.

"He has been removed to his home in the city," answered George Granbury.

"Is he better?" questioned Dick.

"They say he is better some days, but at other times he is worse. The poison somehow affected his mind."

"What a terrible thing to happen," murmured the eldest Rover, and then shuddered to think what might have ensued had the snake bitten him.
