20 CELL INTELLIGENCE THE CAUSE OF EVOLUTION 



erned by the source of light as the direction of the move- 

 ments of the planets is determined by the force of grav- 

 ity." 



Certainly Mr. Loeb must know that the cells who build 

 these aphides or plant lice are- in every way similar and 

 identical to the cells that build him or Mr. Rockefeller. 

 They are of exactly the same size and general appearance. 

 I think the cells that build the plant lice show an extra- 

 ordinary amount of skill and intelligence. As long as the 

 rose bush was living, they were satisfied and contented 

 because they had enough to both eat and drink. When 

 Mr. Loeb dried up the rose bush and deprived them of 

 food and drink, they had to get out of there and go some 

 place where they could procure those things necessary to 

 their life. They are compelled to do this just as Mr. Loeb 

 would have to do under similar circumstances or starve 

 to death. The plant lice could clearly see that there was 

 nothing to eat and drink within any reasonable distance 

 of where they were stranded. It looked to them like a 

 "Long way to Tipperary." The only method by which 

 they could save themselves from starvation was to pre- 

 pare temporary wings and fly, which they did. Now 

 where or in what direction should they fly? Anyone with 

 sense would go straight to the place which would look 

 like an opening in the prison or house in which they were 

 enclosed. The light in the window would be the only 

 thing that would direct them to a way to get out and find 

 another green plant which is their only source of food and 

 drink. What more could Mr. Loeb have done if he had 

 been in their place? Endowed with the intelligence that 

 Mr. Loeb and Mr. Rockefeller are now supposed to have, 

 what more could they have done to save themselves from 

 starvation? The intelligence, skill and knowledge pos- 

 sessed by the builders of the plant lice to be able to build
