There were two articles in Amateur Scientist column of the 
"Scientific American" that mention Elmer Rixon and his
water-well seismograph.
   June, 1953 - page 117 - has about a page of text
           text and a large diagram
   May, 1961 - page 182 - almost two pages starting
           discussing Elmer Rixon's work, and continuing
           mentioning Gerald I. Shea's work, with
           more diagrams and recordings

If you are interested, and cannot get microfilm type
images from your local library, I can scan and send
the articles to you.

Reference to the above articles is in the web site
for Society for Amateur Scientists at
under "Seisograph".

The Society for Amateur Scientists has obtained rights
to make a CD of all Amateur Scientist columns of the 
"Scientific American".  You can check for the progress at

Elmer Rixon and Gerald Shea were early founders of the 
World Amateur Seismological Society (WASS) that 
published a quarterly newsletter/journal during
the 1960's to 1975.
