[Illustration: ARGIOPE, THE MEADOW SPIDER] Strangely enough here on the roof I have watched the only nighthawks that I have ever found in Massachusetts. This is surely the last place you would expect to find such wild, spooky, dusk-loving creatures as nighthawks. Yet here, on the tarred and pebbled roofs, here among the whirling, squeaking, smoking chimney-pots, here above the crowded, noisy streets, these birds built their nests,--laid their eggs, rather, for they build no nests,--reared their young, and in the long summer twilight rose and fell through the smoky air, uttering their peevish cries and making their ghostly booming sounds with their high-diving, just as if they were out over the darkening swales along some gloomy swamp-edge. For many weeks I had a big tame spider in the corner of my study there in that city flat, and I have yet to read an account of all the species of spiders to be found dwelling within the walls of any great city. Even Argiope of the meadows is doubtless found in the Fens. Not far away from my flat, down near the North Station, one of my friends on the roof of his flat kept several hives of bees. They fed on the flowers of the Garden, on those in dooryards, and on the honey-yielding lindens which stand here and there throughout the city. Pigeons and sparrows built their nests within sight of my windows; and by going early to the roof I could see the sun rise, and in the evening I could watch it go down behind the hills of Belmont as now I watch it from my lookout here on Mullein Hill. One is never far from the sky, nor from the earth, nor from the free, wild winds, nor from the wilder night that covers city and sea and forest with its quiet, and fills them all with lurking shadows that never shall be tamed. CHAPTER VI A CHAPTER OF THINGS TO HEAR THIS SUMMER I The fullness, the flood, of life has come, and, contrary to one’s expectations, a marked silence has settled down over the waving fields and the cool deep woods. I am writing these lines in the lamplight, with all the windows and doors open to the dark July night. The summer winds are moving in the trees. A cricket and a few small green grasshoppers are chirping in the grass; but nothing louder is near at hand. And nothing louder is far off, except the cry of the whip-poor-will in the wood road. But him you hear in the spring and autumn as well as in the summer. Ah, listen! My tree-toad in the grapevine over the bulkhead door!
