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.

Night-vision devices using active near-infrared illumination allow people or animals to be observed without the observer being detected. Infrared astronomy uses sensor-equipped telescopes to penetrate dusty regions of space, such as molecular clouds; detect objects such as planets, and to view highly red-shifted objects from the early days of the universe. Infrared thermal-imaging cameras are used to detect heat loss in insulated systems, to observe changing blood flow in the skin, and to detect overheating of electrical apparatus.

The onset of infrared is defined (according to different standards) at various values typically between 700 nm and 800 nm, but the boundary between visible and infrared light is not precisely defined. The human eye is markedly less sensitive to light above 700 nm wavelength, so longer wavelengths make insignificant contributions to scenes illuminated by common light sources. However, particularly intense near-IR light (e.g., from IR lasers, IR LED sources, or from bright daylight with the visible light removed by colored gels) can be detected up to approximately 780 nm, and will be perceived as red light. Sources providing wavelengths as long as 1050 nm can be seen as a dull red glow in intense sources, causing some difficulty in near-IR illumination of scenes in the dark (usually this practical problem is solved by indirect illumination). Leaves are particularly bright in the near IR, and if all visible light leaks from around an IR-filter are blocked, and the eye is given a moment to adjust to the extremely dim image coming through a visually opaque IR-passing photographic filter, it is possible to see the Wood effect that consists of IR-glowing foliage. 1. what doesn't have a precise definition?

input: Make use of the article to answer the questions. (CNN) -- The goals just keep flowing for Lionel Messi, who on Sunday surpassed soccer legend Pele's mark of 75 in a calendar year to help Barcelona bounce back from a rare defeat.

The Argentina star netted twice in the 4-2 win at Mallorca that kept the Catalans three points clear in Spain's La Liga, leaving him just nine short of Gerd Muller's all-time record.

The 25-year-old, who became a first-time father earlier this month, was able to put a bit more enthusiasm into his new thumb-sucking celebration than when he scored late in the shock midweek Champions League loss to Scottish side Celtic.

"Leo continually breaks records. His goal tally is spectacular," said Barca manager Tito Vilanova, who has yet to experience a domestic league defeat after his first 11 matches in charge, equaling the best start to a season set by Real Madrid.

"It takes other great players seven or eight seasons to score the amount of goals he scores in one season. Also, some of his goals are absolute beauties."

Read blog: Is loyalty Barca's biggest strength?

Messi has now scored 64 goals for his club and 12 for his country this year, from just 59 matches overall.

Pele managed 75 from 53 as a 17-year-old in 1958, helping Brazil to win the World Cup for the first of a record five times.

Muller, a World Cup winner in 1974, surpassed Pele's record in a year that West Germany won the European Championship.

Messi has yet to win a senior title with Argentina, though he won Olympic gold with the under-23 side in 2008. 1. Who surpassed Pele?
