I. E. S. convention at Cleveland

As has already been announced, the date for the next annual convention of the Illuminating Engineering Society, originally set for September 27–30, has been changed to October 4–7. The change was made to avoid conflict with the American Legion Convention to be held in Cleveland the last week in September it being felt that the gathering together, in one city and at the same time, of the two organizations, would cause Cleveland's visitors to suffer inconveniences.
