Nor is it to be overlooked that efficiency and salaries must mount upward together. It would be as unjust to ask for higher salaries without increasing the grade of efficiency as to ask for efficiency on the present salary basis. It is probable that the eighteen- or nineteen-year-old boys and girls starting in to teach the rural school, with but little preparation above the elementary grades, are receiving all they are worth, at least as compared with what they could earn in other lines. The great point of difficulty is that they are not worth enough. The community cannot afford to buy the kind of educational service they are qualified to offer; it would be a vastly better investment for the public to buy higher teaching efficiency at larger salaries. No statistics are available to show the exact percentage of increase in rural teachers' salaries during recent years, but this increase has been considerable; and the tendency is still upward. In this as in other features of the rural school problem, however, it will be impossible to meet reasonable demands without forsaking the rural district system for a more centralized system of consolidated schools. To pay adequate salaries to the number of teachers now required for the thousands of small rural schools would be too heavy a drain on our economic resources. Under the consolidated system a considerably smaller number of teachers is required, and these can receive higher salaries without greatly increasing the amount expended for teaching. In this as in other phases of our educational problems, what is needed is rational business method, and a willingness to devote a fair proportion of our wealth to the education of the young. _Supervision of rural teaching_ Our rural school teaching has never had efficient supervision. The very nature of rural school organization has rendered expert supervision impossible, no matter how able the supervising officer might be. With slight modifications, the office of _county superintendent_ is, throughout the country, typical of the attempt to provide supervision for the rural school. While such a system may have afforded all that could be expected in the pioneer days, its inadequacy to meet present-day demands is almost too patent to require discussion.
