E-bay had a copy of "Principles Underlying the Interpretation of
Seismograms", U.S. Dept. of Commerce Special Publication 254 (revised 1966
edition) for sale a few months ago.  I think it went for about $65.
However since the publication is out of print, the winning bidder was kind
enough to send me a xerox copy of the book.

If anyone on our list would like a copy of this document (about 50 pages),
send me $5 to cover copying and shipping costs and I'll be glad to make you
a copy.  Address is 238 Highland St., Portsmouth, NH 03801.

Regards, Ted
