King Oscar took a deep personal interest in naval affairs, because his early life was spent in the navy, his commission as lieutenant bearing the date of June 19, 1845. When he was called to the throne, he at once commenced to plan for improvement of that branch of the service, and for many years was virtually his own minister of marine. He did much to encourage the maritime spirit among the people, being honorary president of the Royal Yacht Club, and presided over its meetings, which were sometimes held in the palace to suit his convenience. He took an active part in the organization and promotion of the naval reserve, and never lost an opportunity to show his zeal in the development of the shipping industry and the aquatic pastimes. Nor was the king a paper sailor. On special occasions he showed great bravery and presence of mind at sea, and of his sixty decorations and medals he valued none higher than that which was awarded him by the Humane Society of France in 1862, when he saved the lives of three people at the risk of his own. The Swedish militia is commanded by officers of the regular army. No man can receive a commission in the militia unless he has spent at least sixteen months in the military academy and passed the required examinations. About a thousand young men are graduated each year from the several schools situated in different parts of the country, which are a part of the regular educational system of the nation. Thus the government has at its command abundant material for the military organization. The officers are promoted as vacancies occur, are retired on half pay when they are aged or disabled--generals at 65 years, colonels at 60, lieutenant colonels and majors at 55, and captains at 50. Militia officers are eligible to appointments in the civil service; they may be elected to the riksdag, and they have the same social standing at the palace as the officers of the regular army. The palace is the center of the social system in Sweden, and only certain persons are eligible to invitations to the king's balls and dinners. All officers of the militia are included in the list, and all peasants in the riksdag, although their wives are never invited.[h] CHAPTER IX PUBLIC EDUCATION There are few countries in which education is as free as in Sweden. From the grammar school to the university in all its stages, the cost is defrayed entirely by the state or the parish. Education is thus not a privilege of the wealthy, but a benefit common to all. In Norway you are scarcely ever out of sight of a schoolhouse, and Professor Nielsen, of the university, on being asked concerning the ratio of the illiterates, looked surprised and replied that he was not aware of any illiterates; that he did not recollect having seen any statistics on the subject, and ventured to assert that anybody in Norway could both read and write.
