Editorial

Christmas is here again! This is our Christmas issue. Unfortunately, we are not able to make it a bumper issue, as we might have done under normal conditions. In fact, we feel quite happy and satisfied with being able to maintain our present standard in the face of the dozen and one little problems which arise at times like this. Looking back over the year, too, we find plenty to be happy about. The success of Parry's articles on acoustic compensation, the popularity of the special features for dealers, and particularly those on signal tracing, are all reflected in a substantial increase in circulation. Since our ration of paper has to cover this increased circulation, we find that we can't have as many pages in each issue as we could readily fill, but we are doing the best we can under the circumstances. It gives us great satisfaction to know that our readers appreciate the difficulties and maintain their loyal support, and so it is with the fullest sincerity that we wish you all — A Merry Christmas and a Happy New Year
