There will be joint meetings of the AHS- American Section and Horological Science at the NAWCC Seminar Thursday evening, October 17, 2002,

7 pm-- Will Andrewes will give an illustrated talk on "French Clocks In American Collections." Will is well known for having been the Curator of the Time Museum collection. He is also the author of a splendid book on the 1993 Longitude Symposium, which he chaired.

9:30 pm-- Ernest Martt will talk on "Design of Missing Parts in a Dead-Beat Escapement." His program uses MS Excel for rapid calculations. After these meetings there will be open discussion of member's projects.

There are 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 November 15th.

Bob Holmström
