knot at first, or after one trial at his end of the rope. He would 

 also sometimes claw slightly at the knot itself. When, finally, 

 I moved the knot to a bar beyond his reach, after a slight trial at 

 the straight cord, he would pull the other. 1 For Jimmy, I ar- 

 ranged a cord knotted to the handle of a writing-desk. He was 

 tied to a heavy chair, by moving which I could let him reach 

 beyond the knot, or prevent him, at pleasure. When I let him 

 do so, he at once reached beyond the knot, even if he had to 

 make a great stretch for it. When I put the chair back, he did 

 not try to use a stick to rake in the free cord, but at first pulled 

 the tied part fruitlessly, and then taking it in both hands, pulled 

 so hard as to drag his chair forward, whereupon he immediately

reached out, and caught the cord beyond the knot. This was 

 repeated, and if at first accidental, certainly became deliberate. 

 On the other hand, if the chair was held fast, he would not at 

 first try to use the stick to fish for the string, but would pull 

 irrationally at the tied string. 2 The next day, however, he took 

 to the stick, and thereafter used it freely. He would now wholly 

 disregard the tied string, unless he wished to pull himself forward 

 by means of it. 



1 There followed two trials in which he attempted the wrong rope first 

 and then pulled the right. He then pulled the right five times running. 

 The ends of the rope lay close together, and were indistinguishable in 

 appearance. 



2 The stick was placed in position for him several times, and then he 

 used it, but he only once that day made an effort to get it into position 

 himself.
