made; and in writing the book I was successively a sandpiper, a crab, a mackerel, an eel, and half a dozen other animals. Hardest of all, I had to get the feel of a world that was entirely water.
I very soon realized that the central character of the book was the ocean itself. The smell of the sea’s edge, the feeling of vast movements of water, the sound of waves, crept into every page, and over all was the ocean as the force dominating all its creatures.
In order to give a fairly complete picture of sea life, I divided the book into three parts, one to picture the life of the shore, one for the open sea, and one for the deep abyss. In each of these parts, or books, I told the life story of one particular animal.
Book I – Edge of the Sea
Almost everyone knows the sea beach in a general way. Unfortunately, though, most people stay within sight of the piers and boardwalks of a resort beach, and never become acquainted with the animals of the beach, except for the few whose remains may be found in the litter along the high-tide mark. I always seek out the wild sections of beach that are usually to be found a few miles above or below a resort. One particularly lovely stretch of wild ocean beach in North Carolina forms the setting for most of the chapters about the shore. It is a beach that is separated from the mainland towns by a wide sound, fringing one of those narrow strips of outer land which the Carolinians call “banks.” I have visited that beach in spring and fall to watch the comings and goings of the shorebirds. I have spent hours on end among the dunes or on the beach, saturating myself with the sounds of water and the feel of hot sun and blowing sand. I have watched the fiddler crabs and ghost crabs, and, in autumn, seen the mullet fishermen draw their seines on the beach. This was the background for the story of a bird that almost everyone who has visited the beach has seen as it runs along at the edge of the waves – a special kind of sandpiper called a sanderling. I chose the sanderling as the main character of the shore section because of its fascinating life story. The sanderling is one of the bird tribe’s long-range migrants. I believe that few of the people who like to watch the sanderling on the beach have any idea of the hardships these birds endure, or the long and hard flights they make. Some of them actually travel more than eight thousand miles every spring and return the same distance every fall. These little birds winter as far south as Patagonia, at the extreme southern end of South America, and in the spring they migrate northward, most of them beyond the Arctic Circle, and some to within a few miles of the North Pole. This seems a strange place to choose to rear their young, but many of the shore and ocean birds nest in the Arctic. Probably they are obeying some instinct inherited from forgotten generations of ancestors. We see the sanderlings in the spring as they are migrating up along our coastline, then, about May and June in Maryland and Virginia, all but a few immature birds disappear. This is during the period when the adult birds are nesting on the Arctic tundras. When they first arrive in the Arctic the snow and ice have not melted, food is scarce, and late-season blizzards may take a heavy toll of life. Eventually, spring comes even to these frozen tundras, the birds prepare their nests and lay their eggs, and the young are hatched. There are many enemies abroad on the tundra. Some of these are the large snowy owls, the foxes, and hawk-like birds of the gull tribe known as jaegers. After the chicks have hatched, the mother sanderling takes great precautions to hide the egg shells, so that enemies will not be led to the nest by them. Usually she leads the young away from the nest when they are only a few days or even hours old, if she has been frightened by marauders. Very quickly, however, the young become able to take care of themselves. As soon as they are no longer needed,
