Any treatment of the values which are attached to membership in extra-curricular activities on the part of high-school students must take definitely into account the actual extent of the participation. Participation in extra-curricular activities, to a very large degree, has been made a matter of voluntary effort on the part of students, so that the administrative organization of a fine variety of extra-curricular activities does not, in itself, guarantee that all pupils will be properly cared for. On the contrary, it may very well be that a considerable percentage of the pupils are not being reached by the extra-curricular offering and that they complete their school course practically immune to the important socializing influences which are being encountered by a majority of the high-school pupils.

Scientific investigation of the materials and activities which are involved in learning to draw has not developed a body of information from which may be formulated a full set of rules to govern instruction in drawing. It cannot be claimed that the significant advances which have been made in the scientific study of the fundamental subjects of reading, writing, spelling and arithmetic have in any degree been paralleled in the field of drawing. No mention has been made of drawing in the excellent studies on economy of time and minimal essentials.
