Struensee, who was a believer in the famous treatment of Emile, changed all this, and urged the Queen to bring up her son as simply as possible, so that he would grow up to be a strong and a self-reliant man. The Crown Prince's former attendants were sent away, and he was given the simplest fare, consisting of vegetables, rice boiled in water, bread and water, and milk and potatoes; no meat was allowed him. He wore light silk clothes, and went about bare-footed. He was bathed twice a day in cold water, and soon became so fond of it that he would go into the bath of his own accord. He was forced to take exercise, kept as much as possible in the open air, and made to run about the gardens in all weathers. His room at Hirschholm was a large one on the ground floor, some forty feet in length, and on the garden side it was closed in by an iron trellis-work, which accounted for the story that the heir to the throne was shut up in a cage. The little Prince had only one playmate, a boy who was the natural son of one of the court surgeons, and known as "little Karl". These boys were always together, and no difference was made between them. They played, quarrelled and fought as they would, and no one was allowed to interfere with them, nor were any of the servants about the court suffered to speak to, or play with, the Crown Prince. This rule was kept very strictly. For instance, one day, when the little Prince fell in the garden and hurt himself, Struensee's valet, who was passing, picked him up and tried to comfort him. For this breach of rule the servant was sent to the Blue Tower in Copenhagen and imprisoned for some time. The boy was not allowed on any pretext to take advantage on the ground of his rank. One day when he and his companion had some quarrel, Frederick asked Karl how he dared to strike a prince. "I am as much a prince as you," the other boy answered. "Yes, but I am a Crown Prince," Frederick retorted. Thereupon the two boys fought till Frederick won the victory. Struensee heard of this battle royal, and told the Queen, who, when she knew the cause, insisted on the Crown Prince begging the other boy's pardon. As Frederick refused to do so, the Queen gave him a whipping. From this arose the rumour that he was frequently severely beaten. The charge that he was neglected rests on more foundation. One day during the autumn of 1770, at Hirschholm, the King and Queen and all the court went out hunting, and on their return very late the Crown Prince could nowhere be found. A search was made for him, and he was at last found lying insensible in the garden half-dead with cold. He was put to bed with a nurse, who took him in her arms and gradually restored him. The negligence in this case was due to the servants who had been left in charge of him, but the blame was laid upon the Queen.
