Air Power.
Twenty years ago red-lined maps, the red lines indicating British shipping services and trade routes were familiar exhibits, combining information with national propaganda. The map-makers of those days knew sea lines and land lines but not air lines. To-day they would be busy drawing airlines from the British Isles across Europe to the Eastern Mediterranean, thence bifurcating to India and South Africa. A red line would run up the Upper Nile (where Gordon died and Kitchener fought), across the Great Lakes (lakes of romance!) and over Congo forests to the Zambesi. And if the mapmakers were very up-to-date they would continue the red line from India to Australia—the latest commitment of the British and Australian Governments, to which New Zealand also gives a subsidy.
