Frank,

Thanks for posting this fascinating article.  No errors in the circuit
diagrams either!  :-)  This guy was clearly a tinkerer in the mold of the
Wright brothers.

Subject:  1938 amateur seismology article



Hi,
I have included a five page1938 article on how to construct your own
seismograph from Modern Mechanix on my web page at:
http://freeweb.pdq.net/fxc/  The web page SEISMOLOGY IN FRIENDSWOOD, TEXAS,
USA, will take several minutes to download.

I think many PSN members will be interested in the 1938 methods of
constructing an amateur seismograph.  How different it is today!
Regards,
Frank Cooper, Friendswood, Texas
