They are to be eaten with great care, and to ensure permanency in the results, a green leaf of the little tree is to follow the consumption of the bean." Burton sprang to his feet.
"A thousand thanks, professor!" he cried.

"That is the one thing we were seeking to discover.

The leaves, of course!" Mr.Cowper looked at his visitor in amazement.
"My young friend," he said, "are you going to tell me that you have seen one of these beans ?" "Not only that but I have eaten one," Burton announced,--"in fact I have eaten two." Mr.Cowper was greatly excited.
"Where are they ?" he exclaimed.

"Show me one! Where is the tree?
How did the man come to write this?
Where did he write it?
Let me look at one of the beans!" Burton produced the little silver snuff-box in which he carried them.
With his left hand he kept the professor away.
"Mr.Cowper," he said, "I cannot let you touch them or handle them.
They mean more to me than I can tell you, yet there they are.

Look at them.
