A few hours later the land asserts itself again. The sea draws back sullenly at first. Soon its retreat becomes a very flight. The narrow ways between the islands, calm an hour before, are like swift rivers. Through the cleft gaps in the breakwater of boulders the sea goes back from its adventurous wanderings to the ocean outside; but not as in other places, where a deep felt homing impulse draws tired water to the voluminous mother bosom of the Atlantic. Here, even on the calmest days, steep wavelets curl and break over each other, like fugitives driven to desperate flight by some maddening fear, prepared, so great is the terror behind them, to trample on their own comrades in the race for security. One after another all over the bay the wrack-clad backs of rocks appear. Long swathes of brown slimy weed, tugging at submerged roots, lie writhing on the surface of the ebbing streams. The islands grow larger. Confused heaps of round boulders appear under their western bluffs. Cormorants perch in flocks on shining stones, stretching out their narrow wings, peering through tiny black eyes at the withdrawal of the sea. On the eastern shores of every island, stretches of pebble-strewn mud widen rapidly. The boats below the cottages lie dejected, mutely re-reproachful of the anchors which have held them back from following the departed waters. Soft green banks appear here and there, broaden, join one another, until whole stretches of the bay, miles of it, show this pale sea grass instead of water. Only the few deep channels remain, with their foolish stranded buoys and their high useless perches, to witness to the fact that at evening time the sea will claim its own again.
