The Edge of the Sea

Preface

LIKE THE SEA ITSELF, the shore fascinates us who return to it, the place of our dim ancestral beginnings. In the recurrent rhythms of tides and surf and in the varied life of the tide lines there is the obvious attraction of movement and change and beauty. There is also, I am convinced, a deeper fascination born of inner meaning and significance.

When we go down to the low-tide line, we enter a world that is as old as the earth itself—the primeval meeting place of the elements of earth and water, a place of compromise and conflict and eternal change. For us as living creatures it has special meaning as an area in or near which some entity that could be distinguished as Life first drifted in shallow waters-reproducing, evolving, yielding that endlessly varied stream of living things that has surged through time and space to occupy the earth.

To understand the shore, it is not enough to catalogue its life. Understanding comes only when, standing on a beach, we can sense the long rhythms of earth and sea that sculptured its land forms and produced the rock and sand of which it is composed; when we can sense with the eye and ear of the mind the surge of life beating always at its shores—blindly, inexorably pressing for a foothold. To understand the life of the shore, it is not enough to pick up an empty shell and say “This is a murex,” or “That is an angel wing.” True understanding demands intuitive comprehension of the whole life of the creature that once inhabited this empty shell: how it survived amid surf and storms, what were its enemies, how it found food and reproduced its kind, what were its relations to the particular sea world in which it lived.

The seashores of the world may be divided into three basic types: the rugged shores of rock, the sand beaches, and the coral reefs and all their associated features. Each has its typical community of plants and animals. The Atlantic coast of the United States is one of the few in the world that provide clear examples of each of these types. I have chosen it as the setting for my pictures of shore life, although—such is the universality of the sea world—the broad outlines of the pictures might apply-on many shores of the earth.

I have tried to interpret the shore in terms of that essential unity that binds life to the earth. In Chapter I, in a series of recollections of places that have stirred me deeply, I have expressed some of the thoughts and feelings that make the sea’s edge, for me, a place of exceeding beauty and fascination. Chapter II introduces as basic themes the sea forces that will recur again and again throughout the book as molding and determining the life of the shore: surf, currents, tides, the very waters of the sea. Chapters III, IV, and V are interpretations, respectively, of a rocky coast, the sand beaches, and the world of the coral reefs.

The drawings by Bob Hines have been provided in abundance so the reader may gain a sense of familiarity with the creatures that move through these pages, and may also be helped to recognize those he meets in his own explorations of the shore. For the convenience of those who like to pigeonhole their findings neatly in the classification schemes the human mind has devised, an appendix presents the conventional groups, or phyla, of plants and animals and describes typical examples. Each form mentioned in the book itself is listed under its Latin as well as its common name in the index.
