The pilot in the back seat examines his instruments, and soon there is a hissing noise as he turns on the compressed air. The propeller in front of me moves round slowly. The engine fires and begins to start with a roaring noise.

The propeller vanishes as it gathers speed, and I can see straight ahead with an uninterrupted view.

The engine is tested with men hanging on to the wings. The pilot waves his hand, the men leave go, and we begin to move out across the wide harbour with its grey battleships and lean destroyers, and merchant ships painted in strange patches.

The moon is growing paler now, and nearly all the stars have vanished before the silver of the dawn. On our right is the outline of a red-roofed harbour town, quiet and asleep. On the left are the great sheds of the station, and the low green hills beyond. We face the wind. The engine recommences its roar, and the seaplane begins to move quickly across the water with a steady noise. Faster and faster it rushes on, then begins to leap from wave-top to wave-top until we rise into the air, and move at a rushing pace just over the pale oily water.

The roar of the motor is soon registered no more by my ear, lulled by its perpetuity. I find it glorious to be winging my way into the heart of the dawn over the silver water. Above a long floating boom we pass, and turn east towards the wide misty level of the sea. Ahead of me in the haze burns a red-eyed sun, looking hot and only half awake.

Far to my left and far to my right is a faint grey coast-line as we move up the widening estuary. I bring out a little blue-covered note-book, and sharpen a pencil and prepare to record the name, nationality, and type of every ship, with a brief note of its cargo, course, and characteristics.

Through the haze suddenly appears a little group of ships anchored round a stout red lightship, with its great lantern at the top of the mast and the cheery white-painted name on its side.

My pencil is very busy as we sweep round in circles, while I make notes of the different types of ships. Neutral ships being luridly decorated with painted colours and their names in enormous white letters, are easily recorded. It is somehow very dramatic to see a great steamer loom through the mist, and to read Jan Petersen-Norge or Hector-Sverige on its black sides as it sweeps majestically under the seaplane, its churning propeller leaving a wide lane of white bubbling foam.

It gives such a splendid idea of far-flung commerce—of nation linked up with nation by these loaded ships. You realise how the forests of Scandinavia have been despoiled to fill these decks with the towering piles of clean fair wood. There is something in the passing of the great ship proclaiming its nationality and origin in such bold characters that seems like the triumphant note of an organ.

Yet these signs are the heartfelt appeal of an apprehensive and vulnerable vessel, hoping against hope that the vivid stripes of colour and the proclamation of nationality will protect it from the cruel, greedy submarine.
