of himself to the enterprise as will enable him to attain the goal and
directs the remainder of himself to adventures along the line of his
native tendencies. The only way by which we can develop a complete Sam
Brown is so to arrange matters that the whole of Sam Brown is enlisted in
the work. Otherwise we shall have one part of the boy working in one
direction and another part in another direction, and that plan does not
make for completeness. We must enlist the whole boy or we shall fail to
develop a complete boy. If we can find some study to which he will devote
himself unreservedly, then we may well rejoice and can afford to let the
traditional subjects of the course of study wait. We are interested in Sam
Brown just now and he is far more important than some man-made course of
study. We are interested, too, in one hundred per cent of Sam Brown, and
not in three fourths of him. If arithmetic will not enlist all of this boy
and nature will enlist all of him, then arithmetic must be held in
abeyance in the interest of the whole boy.

The seventy-five per cent standard is repudiated by the world of affairs
even though it is emphasized by the school. Seventy-five per cent of
accuracy will not do in the transactions of the bank. The accounts must
balance to the penny. The figures are right or else they are wrong. There
is no middle ground. In the school the boy solves three problems but fails
with the fourth. None the less he wins the goal of promotion. Not so at
the bank. He is denied admission because of his failure with the fourth
problem. Seventy-five will not do in joining the spans of the great bridge
across the river. We must have absolute accuracy if we would avoid a wreck
with its attendant horrors. The druggist must not fall below one hundred
per cent in compounding the prescription unless he would face a charge of
criminal negligence. The wireless operator must transcribe the message
with absolute accuracy or dire consequences may ensue. The railway crew
must read the order without a mistake if they would save life and property
