ROCKKT EXPERIMENTS OF DR. R. H. OODD.MJD 



For the past 12 years the Institution has supported by annual 

 grants the researches of Dr. R. H. Goddard, of Clark University, on 

 the development of a rocket to explore the upper atmosphere. In 

 191 G Doctor Goddard presented to the Institution such a convincing 

 mathematical demonstration of the theory that a self-propelling 

 rocket could be sent to the limit of the earth's atmosphere, and even 

 beyond, that Doctor Walcott, then Secretary of the Smithsonian, 

 after consultation witli a committee of experts, agreed to support the 

 investigation. The work progressed so favorably that the Institu- 

 tion has continued its support until tlie present time.
