The 2004 NAWCC Seminar will be held in Portland in late October. The seminar will be co- hosted by Pacific
Northwest Chapter 31 & the Horological Science Chapter 161. The topic will be Science and Horology.
The proposed display will be a "hands-on" laboratory for horological measurements which can
be operated by seminar attendees. I am looking for suggestions for speaker topics, speakers, experiments
for the "laboratory" and volunteers to help with the seminar and seminar planning.
There are no Rock the Boat items in this issue. These are meant to be comments no longer than half
a page on horological topics, including controversial ones, but not personal. This is a quick way to write
a short article, convey an important idea or ask a question.
The deadline for material for the next issue is March 15th.

time at night from the Great Bear.
