P., which in its September issue suggested that those able to do so make the trip to the annual exhibits. He claims he "was badly fooled and disappointed" because displays had little to show in the way of improvements. We are sorry that our friend found his trip unprofitable from an educational standpoint, but we believe he is the one to blame. In a letter to I. P. he enumerates some of the equipment he saw, but does not mention several important exhibits where manufacturers had technicians and demonstrators on hand to explain them to visiting projectionists. Perhaps at forthcoming exhibits the associations will issue a directory of exhibitors, with room numbers and other pertinent information relating to displays, that would aid visitors who are interested enough in their work to spend their own time and money to make the trip.
