One of the most important elements in a regular service by aeroplanes, especially during winter months, is the provision of adequate light to guide the pilots. Several aerial lighthouses are accordingly being established to enable the service between London and Paris to he maintained without interruption. Two lights are alrcadv in operation. Each lamp gives a powerful vortical and horizontal beam and also a distinguishing signal visible to an airman for many miles. The foundations have been laid of another aerial lighthouse which will have a dash light of 56.000 candle power visible under normal conditions for a distance of 32 miles. Another even more powerful light will shortly be added: and when all the lighthouses are in operation regular night services will be established. In connection with British aviation enterprise it is worth noting that there has been a. steadily increasing use of the air mail service between Cairo and Baghdad. The average time cf transmission by ordinary mail between London and Baghdad is 27 days, but, when letters are transmitted from Cairo to Baghdad oy air the average time is twelve days, and on several occasions the period has been reduced to 10 days. Owing to the success of the service the mail fee lias been considerably reduced.
