Closing address

When this Conference was first proposed I had intended it to be directed solely towards civil and structural engineers. The suggestion that earthquake instrumentation should be included worried me, lest the diet enjoyed by engineers should be indigestible to seismologists and vice versa. I do not think that I need have worried unduly for the papers have been consistently interesting and the discussions lively. Indeed, I feel sorry to have had to interrupt the discussion on the last session.

It is gratifying to see so many engineers taking an interest in vibration instrumentation. I hope this is because they are becoming more aware of their impact on the environment rather than because they are being forced to do so by the Control of Pollution Act.
