The robber was much surprised to see the queen and the prince alone, with their clothes torn and stained, and their faces white from hunger and fatigue. But he was a kindhearted man, although his looks were rough, and before he became a robber he had been a follower of King Henry, so he was quite willing to do his best for the little prince. He took the boy in his arms, and led the way to a cave in the forest, where he lived with his wife. And in this poor shelter, the queen and her son stayed for two days, listening to every sound, and fearing that their enemies would find them. On the third day, however, the friendly robber met some of the lords of the Red Rose in the forest, and led them to the cave. The queen and prince were overjoyed to see their friends, and soon they escaped with them to a place of safety. Their hiding-place has been called "Queen Margaret's Cave" ever since that time. If you go to Hexham Forest, you will be able to see it.

This took a long time to do, so there were not many books, and they were so dear that only the rich could buy them. But after a time, some clever men made a machine, called a printing-press, which could print letters. About that time, an Englishman, named William Caxton, lived in Holland, and copied books for a great lady. He says his hand grew tired with writing, and his eyes became dim with much looking on white paper. So he learned how to print, and had a printing-press made for himself, which he brought to England. He set it up in a little shop in London, and then he began to print books. He printed books of all sorts--tales, and poetry, and history, and prayers, and sermons. In the time which it had formerly taken him to write one book, he could now print thousands. All sorts of people crowded to his shop to see Caxton's wonderful press; sometimes the king went with his nobles. Many of them took written books with them, which they wished to have put into print. Some people asked Caxton to use in his books the most curious words he could find; others wished him to print only old and homely words. Caxton liked best the common, simple words which men used daily in their speech. Caxton did a very good thing when he brought the printing-press to England, for, after that, books became much cheaper, so that many people could buy them, and learning spread in the land.
