The superintendent of schools in a certain city found that his schools were unable to attract the quality of teachers that he wished to employ. He found also that the city was unable to hold many of its best teachers. They were continually resigning and going to cities that placed a higher valuation upon their services. He was continually being compelled to accept inferior teachers, to expend an undue proportion of time in getting them into shape for efficient work, only to find that a large portion of those that became efficient moved on to other cities, leaving the poorer quality of teachers for his service. The harder he worked to bring his teachers up to high standards of teaching ability, the sooner were they ready to leave him, and the sooner had he to begin the work over again with another batch of inferior material. The city could not hope to have effective teaching so long as this was the situation.
