2 Animal Farm pig, with a wise and benevolent appearance in spite of the fact that his tushes had never been cut. Before long the other animals began to arrive and make themselves comfortable after Jessie and Pincher, and then the pigs, who settled down in the their different fashions. First came the three dogs, Bluebell, themselves on the window-sills, the pigeons fluttered up to the straw immediately in front of the platform. The hens perched rafters, the sheep and cows lay down behind the pigs and began to chew the cud. The two cart-horses, Boxer and Clover, came in together, walking very slowly and setting down their vast hairy hoofs with great care lest there should be some small animal concealed in the straw. Clover was a stout motherly mare approaching middle life, who had never quite got her figure back after her fourth foal. Boxer was an enormous beast, nearly eighteen hands high, and as strong as any two ordinary horses put together. A white stripe down his nose gave him a somewhat stupid appearance, and in fact he was not of first- rate intelligence, but he was universally respected for his steadi- ness of character and tremendous powers of work. After the horses came Muriel, the white goat, and Benjamin the donkey. Benjamin was the oldest animal on the farm, and the worst tempered. He seldom talked, and when he did it was usually to make some cynical remark - for instance he would say that God had given him a tail to keep the flies off, but that he would sooner have had no tail and no flies. Alone animals on the farm he never laughed. If asked why, he would among the say that he saw nothing to laugh at. Nevertheless, without openly admitting it, he was devoted to Boxer; the two of them usually spent their Sundays together in the small paddock beyond the orchard, grazing side by side and never speaking. The two horses had just lain down when a brood of duck-

However, as ways of movement go, jet propulsion is not usually a very good use of energy. In the ocean's depths where oxygen gets thin, the nautilus seems to be putting itself at risk by expending so much effort on movement. Fish use far less energy by pushing at the water with their fins. So how does it manage to jet around unscathed in the ocean's depths? Graham Askew, a biomechanics professor at the University of Leeds, set out with a graduate student, Thomas Neil, to understand better how this shellfish moves. They found that the nautilus is actually a highly efficient jet-propelled creature, wasting much less energy than (9)

The night is clear and cold/ Moonlight illuminates the snow/covered land separating the British and German trenches outside a small town in northern France. British military command feeling nervous sends a message to the front lines: it is thought possible the enemy may attack during Christmas or New Year. Extra caution will be maintained during this period. The military command has no idea what's really about to happen.

Christmas trees? /"Stille Nacht, That's when he hears it - soldiers singing in German/" heilige Nacht." Never before had the Christmas music sounded so beautiful. I shall never forget it," Moren says later. It was one of the highlights of my life. Then, in response, the British soldiers start singing The First Noel." The Germans applaud, and counter by singing "O Tannenbaum." They go back-and-forth for a while, until finally the two enemy camps sing "O Come, All Ye Faithful" in Latin, together. "This was really a most extraordinary thing." soldier Graham Williams later recalled, "two nations both singing the same Christmas music in the middle of a war." Events just north of a small town in western Belgium go further still. From the enemy trenches, Corporal John Ferguson hears Someone call out, asking if they want some tobacco. "Come towards the light," shouts the German. So Ferguson walks out into no-man's land into the field between both armies. "We were soon speaking as if we had known each other for years." he later wrote. "What a sight little groups of Germans and British talking together almost as far as the eye can seel Out of the darkness we could hear laughter and see lighted matches.... Here we were laughing and chatting to men who only a few hours before we were trying to kill!" The next morning. Christmas Day, the bravest of the soldiers again climb out of the trenches. Walking past the barbed wire, they go over to shake hands with the enemy. Then they wave "come on!" to those who'd stayed behind. "We all cheered." remembered soldier Leslie Washington of the Queen's Westminster Rifles. "and then we all came out together like a football crowd." (A Gifts are exchanged.
