In the rural sections primary schools are held in comfortable, well equipped, and conveniently located schoolhouses and are taught by competent teachers who live near by in homes provided for them. In a few remote, rugged sections of the country, where children are few and scattering or where locations accessible to all cannot be found, they have no fixed schools, but instead what are termed ambulatory schools (_Omgangskoler_). There are no schoolhouses in these districts but the officials designate certain houses[3] as the places where children go at stated times to receive instruction. The teacher meets the children of the neighborhood in a given home and teaches them for a specified time, passes to the next designated place, and continues until his rounds are completed. Formerly, a very large number of these schools existed, but as roadways were extended or improved and the people became able to erect and maintain schoolhouses, the demand for ambulatory schools decreased until now nearly all of them are supplanted by fixed schools. In 1837, ninety-two per cent of the children attending school in the country were taught in ambulatory schools, while in 1907 this was the case with less than one per cent of them. In all the cities and towns excellent educational advantages are provided. Usually their school year consists of forty weeks of six days each. Every provision is made for the welfare of the children; excellent instructors are secured, and the equipment for teaching purposes is of the best procurable. Furthermore, no pains are spared in guarding the children from physical discomfort and immoral conditions or associations.
