Vajiravudh's style of government differed from that of his father. In the beginning of the sixth reign, the king continued to use his father's team and there was no sudden break in the daily routine of government. Much of the running of daily affairs was therefore in the hands of experienced and competent men. To them and their staff Siam owed many progressive steps, such as the development of a national plan for the education of the whole populace, the setting up of clinics where free vaccination was given against smallpox, and the continuing expansion of railways.
