THEY PROPAGATE 15 



The rapidity with which, by each of these three 

 methods, these wonderful beings reproduce their 

 kind, is quite inconceivable. One in one day of 

 twenty-four hours may become 16,500,000. Of 

 course this rate of propagation could not continue 

 without interruption. Food supply and enemies 

 would not permit. But could this rate continue, 

 in two days the one would become 281,500,000,000. 

 In three days, 27,000,000,000,000. It has been esti- 

 mated that this number weigh about 10,000,000 

 pounds or eight thousand tons!
