customed to catch his food (bread, potatoes, fruit, ete.) with his 
hands, when thrown to him. Sometimes the pieces fell short three 
or four feet. One day he seized his strap and began to throw it 
at the food, retaining his hold of one end. He took pretty correct 
aim, and finally drew the pieces to within reach of his hand. This 
performance he constantly repeats, hooking and pulling the arti- 
cles to him in turns and loops of the strap. Sometimes he loses 
his hold of the strap. If the poker is handed to him he uses 
that with some skill in the recovery of the strap. When this is 
drawn in, he secures his food as before. 
Here is an act of intelligence which must have been originated

sesses the hands necessary for its accomplishment. Whether origi- 
nated by Jack, or by some ancestor of the forest who used vines for 
the same purpose, cannot be readily ascertained.—Epw. D. Core.
