Conclusion -82- 



'greatly retarded or prevented and that possibly much harm 

 can result from storms, droughts, or floods produced by un- 

 controlled seeding. 



"Theory has predicted and experiments are confirming 

 the fact that a few pounds of silver iodide released into the 

 atmosphere in the form of fine particles can exercise a pro- 

 found influence over the weather hundreds of miles away from 

 the point of release. Clearly no private individual or group 

 can be permitted to carry on operations likely to affect weather 

 conditions over thousands or hundreds of thousands of square 

 miles. 



"The potentialities, both for good and bad, which attend 

 silver -iodide seeding are so large that the development and 

 use of this technique must be placed in the hands of the Fed- 

 eral Government. 



"Secondly, it is highly desirable that the Government 

 pass laws regulating cloud seeding, in order to promote the 

 rapid development of this science. Many facts are yet to be 

 learned concerning the best methods of seeding to obtain 

 desirable results. These facts can be determined only by 

 experiments in the atmosphere. The analysis of the results 

 of cloud-seeding experiments is a complicated and difficult 

 problem. If, as in the case at present, many seeding ex- 

 periments are being independently and simultaneously carried 

 out in many places, the problem of analysis becomes even more 

 difficult and frequently impossible. Federal regulation is nec- 

 essary to insure the rapid development of the benefits of 

 cloud seeding. 



"Thirdly, the science of weather control can be of such 

 great benefit to the entire country that the responsibility 

 for its advancement must rest with the Government. Legis- 

 lation should provide funds for research by Government and 

 by private groups into fundamental scientific problems con- 

 nected with the weather." 



At the time of the preparation of this history, no national legislation 

 had yet been enacted to cover any of the needs outlined in the foregoing.
