COMMERCIAL AIR ORGANIZATION

IN this issue we complete the publication of a series of articles on the organization of the equipment and maintenance of an air‐line which, with one intermission, has been appearing in these columns since July last year. The event has sent us back to a reperusal of a more serious and attentive nature than has been possible in the turmoil of monthly preparation for the press; when more attention is perforce paid to the correct placing of commas and the avoidance of misprints than to the general sense of the text. Indeed, we are ashamed to say that we have given the articles a more careful reading even than we did when we originally accepted them for publication, when hardly more than a cursory examination was needed to show their originality and interest.
