TEACHERS' ASSOCIATIONS.

94. District, County and State Teachers' Associations are
recommended as an important method of elevating the standard
of public instruction by mutual conference, interchange of views
and suggestions as to systems of teaching and discipline.

95. These associations being voluntary, it should be the care
of the school commissioners to aid in their organization, to en-
courage attendance, to secure competent lecturers, and to impart
such information as they may be able, as will encourage teachers
in their work, and fit them for the performance of their arduous
and responsible duties.

96. These associations must assemble at least, once in each
school term, on Saturday of some month, and may occupy any
of the school houses; stationery for the use of the meeting shall
be furnished gratuitously by the board of school commissioners.
