From Norden to Norddeich was a run of but three or four miles, but a bad road-bed and a worse engine made the journey a tedious if fitting finale to our painful progress across the East Frisian peninsula. Halting but a few moments at the main station, the train was shunted to a spur which took it right out to the quay where the great dyke bent inward to form a narrow artificial harbour. A few steps across the slippery moss-covered stones, where the falling tide had bared the sloping landing, took us to where a small but powerfully engined steam launch was waiting to convey the party to Norderney. Manned by naval ratings, it had the same aspect of neglect which characterized all of the warships we had visited. The men saluted smartly, however, and on our expressing a wish to remain in the open air in preference to the stuffy cabin, they tumbled below and brought up cushions and ranged them along the deck-house to sit upon. The Allied officers dangled their legs to port, the German officers to starboard, while the ex-sailor and the "plain clothes" detective from the Workmen's and Soldiers' Council disposed themselves authoritatively in the wheel-house. A few minutes' run between heavy stone jetties brought us to the open sea, where the launch began threading a channel which seemed to be marked mostly by buoys, but here and there by close-set rows of saplings, now just beginning to show their scraggly tops above the falling water. It was the sight of these latter marks--so characteristic of these waters--that reminded me that we had at last come out into the real hunting ground of the _Dulcibella_, where "Davies" and "Carruthers" had puzzled out the solution of "The Riddle of the Sands." Norderney and Juist and Borkum and the other of the "seven islands" strung their attenuated lengths in a broken barrier to seaward, and between them and the mainland we were leaving astern stretched the amazing mazes of the sands, alternately bared and covered by the ebb and flow of the tides. Two-thirds of the area, according to "Carruthers," were dry at low water, when the "remaining third becomes a system of lagoons whose distribution is controlled by the natural drift of the North Sea as it forces its way through the intervals between the islands. Each of these intervals resembles the bar of a river, and is obstructed by dangerous banks over which the sea pours at every tide, scooping out a deep pool. This fans out and ramifies to east and west as the pent-up current frees itself, encircles the islands, and spreads over the intervening flats. But the further it penetrates the less scouring force it has, and as a result no island is girt completely by a low-water channel. About midway at the back of each of them is a 'watershed,' only covered for five or six hours out of the twelve. A boat, even of the lightest draught, navigating behind the islands must choose its moment for passing these."
