Ants have appeared, and the upper beach is pitted with their hills; I watch the tiny, red-brown creatures running in and out of buried weed. Just outside each hole, the fine sand is all delicately ascrawl with the small, endless comings and goings. The whole upper beach, indeed, has become a plain of intense and minute life; there are tunnels and doors and pitways everywhere. The dune locusts that were so small in June have grown large and learned to make a sound. All up and down the dunes, sometimes swept seaward out of their course by the west wind, go various butterflies. When I turn up driftwood in the dunes, or walk the wheel ruts in the meadows, crickets race off into the grass.
On the dunes, in open places near thin grass, I find the deep, finger-round mine shafts of the dune spider. A foot below, in the cooler sand, lives the black female; dig her up, and you will find a hairy, spidery ball. During the summer months the lady does not leave her cave, but in early autumn she revisits the world and scuttles through the dune grass, black, fast, and formidable. The smaller, sand-coloured male runs about everywhere. I saw one on the beach the other night, running along in cloudy moonlight, and mistook him at first for a small crab. Later the same night, I found a tiny, sand-coloured dune toad at the very brim of the surf, and wondered if an appetite for beach fleas had led him there.
“June bugs,” Lachnosterna arcuata, strike my screens with a formidable boom and linger there formidably buzzing; let me but open the door, and half a dozen are tilting at my table lamp and falling stunned upon the cloth. On mounded slopes of sand, solitary black wasps scratch themselves out a cave; across my paths move the shadows of giant dragon flies.
The straggling beach peas of the region are in bloom; the west wind blows the grass and rushes out to the rippled levels of a level sea; heat clouds hang motionless on the land horizon, their lower rims lost in the general haze; the great sun overflows; the year burns on.

I have spoken in another chapter of the melting away of bird life from this region during April and May. There was a time when the all-the-year-round herring gulls seemed the only birds left to me, and many of these were immature birds or birds whose plumage was then changing from immature brown to adult white and grey. One cold, foggy morning late in May, I woke to find the beach in front of the Fo’castle crowded with these gulls, for a number of hake had stranded during the night, and the birds had discovered them and come to feed. Some fed on the fresh fish, findings being keepings—I saw various birds defend their individual repasts from late arrivals and would-be sharers with a show of wings and a hostile cry—others stood on the top of the beach in a long, senatorial row facing the sea. The maturing birds were of all tones of white and brown; some were chalky and brown, some were speckled like hens, others were a curious brown-mottled chalky grey. The moults of herring gulls are complicated affairs. There are spring moults and autumn moults, partial moults and second nuptial plumages. Not until the third year or later does the bird seem to assume its full nuptial and adult coloration.
When I first open my eyes on a bright midsummer morning, the first sound that becomes part of my waking consciousness is the recurrent rush and spill of the summer sea; then do I hear a patter of tiny feet on the roof over my head and the cheerful notes of a song sparrow’s home-spun tune. These sparrows are the songbirds of the dunes. I hear them all day long, for I have a pair nesting on the seaward slope of this dune in a clump of dusty miller. My building of the Fo’castle has given them something to sit on, something they can see the world from, and on its ridgepole they perch, singing at life in general with a praiseworthy persistence. The bird really has two songs, one the nuptial aria, the other the domestic tune; it sings the first in the nest-building, egg-laying season, and the second from the close of the honeymoon to the silence in the fall. I was amazed this year at the suddenness of the change. On the afternoon of July 1st I heard the birds on my roof singing aria number one; on the morning of July 2d they had turned the page to aria number two. The songs are alike; they resemble each other in musical “shape,” but the first is much more of a warble than the second.
On throwing open my door on the dunes, the morning sea, and the vast empty beach with its coast guard paths, I find the house being stormed by swallows—they are picking up the half-torpid flies that have spent the night on the shingles and just buzzed off—and on looking north and south along the dunes I see swallows everywhere. The grass glistens in the early morning light, the slant of the sun picks out the ripening spears, the graceful birds swim close above the green. Most of these birds are bank swallows, Riparia riparia, but I often see barn swallows, Hirundo erythrogastra, and tree swallows, Iridoprocne bicolor, scattered in among them. A little after seven o’clock they melt away. Through the day stray birds come foraging, but the swarm is a morning affair. The bank swallows (the bird with whitish underparts and a dark band across the breast) have nests north of Nauset Station in a clay stratum of the great bank; the tree swallows and the barn swallows live farther inland near the farms. Some say that the bank swallows nest in these dunes. I have never found their nests in this living sand, but the swallows may manage it, after all. Time and again have I been astounded at the manner in which animals use this sand as if it were ordinary earth. Not long ago, on the top of big dune, I found that moles had tunnelled a surface of live sand for six or seven feet.
