Little Charles was four years old when he reached Windsor Castle. They celebrated his arrival with great rejoicings, and a day or two afterward they invested him with the title of Duke of York, a still higher distinction than he had before attained. Soon after this, when he was perhaps five or six years of age, a gentleman was appointed to take the charge of his education. His health gradually improved, though he still continued helpless and feeble. It was a long time before he could walk, on account of some malformation of his limbs. He learned to talk, too, very late and very slowly. Besides the general feebleness of his constitution, which kept him back in all these things, there was an impediment in his speech, which affected him very much in childhood, and which, in fact, never entirely disappeared. [Sidenote: His progress in learning.] As soon, however, as he commenced his studies under his new tutor, he made much greater progress than had been expected. It was soon observed that the feebleness which had attached to him pertained more to the body than to the mind. He advanced with considerable rapidity in his learning. His progress was, in fact, in some degree, promoted by his bodily infirmities, which kept him from playing with the other boys of the court, and led him to like to be still, and to retire from scenes of sport and pleasure which he could not share. The same cause operated to make him not agreeable as a companion, and he was not a favorite among those around him. They called him _Baby_ Charley. His temper seemed to be in some sense soured by the feeling of his inferiority, and by the jealousy he would naturally experience in finding himself, the son of a king, so outstripped in athletic sports by those whom he regarded as his inferiors in rank and station. [Sidenote: 1616.] [Sidenote: Charles improves in health.] [Sidenote: Death of his brother.] The lapse of a few years, however, after this time, made a total change in Charles's position and prospects. His health improved, and his constitution began to be confirmed and established. When he was about twelve years of age, too, his brother Henry died. This circumstance made an entire change in all his prospects of life. The eyes of the whole kingdom, and, in fact, of all Europe, were now upon him as the future sovereign of England. His sister Elizabeth, who was a few years older than himself, was, about this time, married to a German prince, with great pomp and ceremony, young Charles acting the part of brideman. In consequence of his new position as heir-apparent to the throne, he was advanced to new honors, and had new titles conferred upon him, until at last, when he was sixteen years of age, he was made Prince of Wales, and certain revenues were appropriated to support a court for him, that he might be surrounded with external circumstances and insignia of rank and power, corresponding with his prospective greatness.
