Julius, and he eagerly and confidently volunteered to do so.

His behavior may best be described by enumeration of the several
attempts made. They include (1) placing the larger box nearly under the
banana and reaching from it. (2) Standing of the larger box on end with
resulting failure because the child could not stand on the sloping edges
of the top of the box. (3) The larger box was turned on its side and the
lighter box drawn up opposite it and stood on end. The child then
mounted the larger box and from it stepped to the top of the smaller.
But the boxes had not been placed beneath the banana, and when the child
reached for it, he found himself several feet away from his prize. (4)
The boxes were moved to a position nearly under the banana and another
futile attempt was made to reach it without placing the smaller box on
top of the larger one, the only position from which the child could
readily obtain it. (5) The piece of board was placed on top of the
larger box and from this height the child again reached upward. (6) The
six-foot stick was taken up and an attempt was made to strike the banana
and thus dislodge it, but it was too securely fastened to be obtained
thus. (7) Attention shifted to other things, and the child played for a
time with the board. Reminded of the banana by the experimenter, he
again tried method (3). (8) He again used the stick on the banana. (9)
The effort to knock the prize to the floor having failed, he became
discouraged and said that he must go home. (10) When told that Julius
was very hungry and wanted the banana, he repeated efforts similar to
those described in (3) and (6).

Up to this time the observations had covered a period of twenty minutes.
The child was now taken from the cage and allowed to play about for
fifteen minutes. Asked then whether he would go back and try to get the
banana, he replied, "No, 'cause I don't want to get it," thus indicating
his discouragement with the situation. When taken into the cage, he,
nevertheless, made the additional attempts indicated below: (11) Use of
one of the boxes. (12) He remarked, "Now I know, I'll get it," and after
so saying, repeated (3). (13) Failing, he turned to me and said, "I
could get it if I was on your head," but he did not, as Julius had done,
lead me to the proper place and try to reach the banana by climbing up
or by urging me to lift him. (14) Later, he played in the boxes,
apparently forgetful of his task. Finally he
