CAUSE OF HEREDITY 309 



laying the egg whether it is to be fertilized or not; in 

 the one event a female and in the other a male bee is 

 formed from it." 



The egg is a cell and it knows how to build any one of 

 these three individual structures. The workers indicate 

 what is wanted and when the cell is placed in the comb it 

 is told by the cells in the Queen what is wanted. The 

 cells of the female bee know at all times by being in close 

 touch with the crowd and the colony just what is most 

 needed in the community and every cell as it is placed in 

 the comb will know what it has to do, and in this manner 

 the swarm is constantly kept in proper proportions. There 

 is nothing more strange in this case than in the case of 

 the butterfly, or in the building of an animal. After the 

 stomach of the animal has been started the cells first 

 begin to gather in crowds here to start the head and there 

 to start the limbs, etc., and unless they understood each 

 other perfectly, they could not possibly go ahead with 

 their work in perfect harmony and understanding and 

 complete a plant or animal. The next and last illustra- 

 tion I shall give in this chapter on heredity is that of the 

 social ants, in order to fully illustrate that there is a guid- 

 ing mind and intellect which directs the course of devel- 

 opment of plants and animals. In many of these classes 

 of social ants there are as many as five different kinds 

 of individuals, such as males, females, workers, soldiers 

 and slaves ; and in one case, some of the insects turn into 

 storage tanks in which the honey is stored and as such 

 are suspended under the roof of their dwellings. Mr. 

 Walker has the following to say in reference to some of 

 these social ants : 



"In some ants such as the driver ants of Africa (Typh- 

 lopone) the physical differences between the queens and 

 neuters is so great that even trained entomologists have
