9 There is reason to believe that the years of experience, without competent direction and supervisisn of that experience, are even less cf a factor than they seem to be in securing increases in salary for teachers. Twe cther factors which are probably much more influential may account for most of the salary increases which are disclosed. One cf these is the fact that not a few teachers are extcnding their preparation during those years in which there are salary increases. The secund factur is the shifting, with experience, of the better teachers to other schools which pay more adequate salaries, as from cne-teacher to graced elementary schools, and from these to hizh schools. The two factcrs may often operate jointiy. In providing information for this report some schccl administrators attached supplementary cbservaticns and explanations. These included: "Due to teacher shortage, science and industrial arts not offered this year;" "Vocational agriculture and music dropped because teachers were not available;" "We are short two full-time teachers;" "Dropping two teachers and combining classes made necessary by shortage of funds3" "Operating this year with three high school and three elementary teachers instead cf six and four respectively as a few years ago". A few schcols report that teachers of music, industrial arts, and vocational agriculture are aployed jointly by two neighboring scheols. Others comment: "This teacher is unsatisfactory but available"; Rev. is teaching as 4 substitute"; "My wife is teaching until we can find someone else quelified for the subjects". A superintendent in a smaller city seys, "1 teach six classes a day, ceach athletics, and take care of administrative duties. Other teachers are carrying similar loads." Another administrator refers to the difficulties imposed by csoperation in war-time situaticns.
