development of seismology so as to meet all needs. In a recent 

 statement he said : 



I feel that in recent years we have made most gratifying progress in our 

 attack upon the problems of seismology in the United States. I can not too 

 highly commend the little groups of men by whom that progress has been 

 accomplished. They have not only worked untiringly individually, but their 

 cooperation with one another has been splendid. 



But I also believe, first, that there is need for increased future effort, and, 

 second, that any such increase will necessitate a more formal means of coordi- 

 nating the activities of the various participating groups. There will be par- 

 ticular need to clarify, and to dovetail together, the respective fields occupied 

 by the two general groups consisting, on the one hand, of the geophysicists, 

 concerned with the pure science of seismology, and, on the other hand, the 

 engineers, architects, and others who are concerned with earthquakes because 

 of their potential menace to life and property.
