"While I was watching, a trainer appeared and 

 snapped his whip. 



"The monkeys quit their play with the dog, 

 ran around in a circle, and climbed up the wire 

 of the cage. 



"The little dog followed them, but could not 

 climb. He would start up and drop back, start up 

 again and drop back again. 



"Then he would look down at his feet, and if 

 a dog ever showed surprise, that dog did. He 

 seemed to be wondering why he could not climb 

 as monkeys do. 



"The environment was there, but the heredity 

 was different. 



"We see the same thing in plant life. 1'he 

 sweet peas with their tendrils and the nasturtiums 

 with their leaves can climb like the monkeys, 

 while other plants can not be forced to climb 

 because there is no climbing heredity within them. 



"You may try to make corn climb a hop pole, 

 or to make hops grow straight in the air without 

 a pole or string. But in a lifetime you can not 

 succeed. 



"It is heredity, heredity, heredity. Environment, 

 unless oft-repeated, only serves to bring heredity 

 out. 



"The climbing monkeys and the disappointed 

 dog show us an important truth in our work.
