Raleigh was not left quite lonely in the Tower. His wife and children, whom he dearly loved, were allowed to come to live beside him. The governor was kind to him and allowed his renowned prisoner to use his garden. And there in a little hen- house Raleigh amused himself by making experiments in chemistry, and discovering among other things how to distill fresh water from salt water. He found new friends too in the Queen and in her young son Henry, Prince of Wales. It was a strange friendship and a warm one that grew between the gallant boy- prince of ten and the tried man of fifty. Prince Henry loved to visit Raleigh in the Tower and listen to the tales of his brave doings by sea and land in the days when he was free. Raleigh helped Prince Henry to build a model ship, and the Prince asked Raleigh's advice and talked over with him all his troubles. His generous young heart grieved at the though of his friend's misfortunes. "Who but my father would keep such a bird in such a cage," he said with boyish indignation. And it was for this boy friend that Raleigh began the book by which we know him best, his History of the World. Never has such a great work been attempted by a captive. To write the history of even one country must mean much labor, much reading, much thought. To write a history of the world still more. And I have told you about Raleigh because with him begins an interest in history beyond the bounds of our own island. Before him our historians had only written of England. It gives us some idea of the large courage of Raleigh's mind when we remember that he was over fifty when he began this tremendous piece of work for the sake of a boy he loved. Raleigh labored at this book for seven years or more. He was allowed to have his own books in prison. Sir Robert Cotton lent him others, and learned friends came to talk over his book with him and help him. And so the pile of written sheets grew. But the book was never finished, for long before the first volume was ready the brave young prince for whom it was written died. To Raleigh, this was the cruelest blow fate ever dealt him, for with the death of Prince Henry died his hope of freedom. In spite of his long imprisonment, Raleigh had never lost hope of one day regaining his freedom. Prince Henry just before his death had wrung an unwilling promise from the King his father that Raleigh should be set free. But when the Prince died the King forgot his promise. "O eloquent, just and mighty death!" Raleigh says in the last lines of his book, "Whom none could advise, thou hast persuaded, what none hath dared, thou hast done; and whom all the world hath flattered, thou only hast cast out of the world and despised; thou hast drawn together all the far stretching greatness, all the pride, cruelty, and ambition of man, and covered it all over with these two narrow words Hic Jacet.
