I am glad to avail myself of the opportunity afforded by your Committee on Meetings to make a brief summary of the program. This Symposium has provided a splendid outlook on the problem of volcanology and, without doubt, has clarified the subject in the minds of those who have been fortunate enough to be present this afternoon. In the time available it is probably not possible to make an adequate summary, but I should like to make a few general comments at this time and to recall the scope of the program.
