As I sit at my window this summer afternoon, hawks are circling about my clearing; the tantivy of wild pigeons, flying by two and threes athwart my view, or perching restless on the white pine boughs behind my house, gives a voice to the air; a fish hawk dimples the glassy surface of the pond and brings up a fish; a mink steals out of the marsh before my door and seizes a frog by the shore; the sedge is bending under the weight of the reed-birds flitting hither and thither; and for the last half-hour I have heard the rattle of railroad cars, now dying away and then reviving like the beat of a partridge, conveying travellers from Boston to the country.

在这一个夏天的下午，当我坐在窗口，鹰在我的林中空地盘旋，野鸽子在疾飞，三三两两地飞入我的眼帘，或者不安地栖息在我屋后的白皮松枝头，向着天空发出一个呼声；一只鱼鹰在水面上啄出一个酒涡，便叼走了一尾鱼；一只水貂偷偷地爬出了我门前的沼泽，在岸边捉到了一只青蛙；芦苇鸟在这里那里掠过，隰地莎草在它们的重压下弯倒；一连半小时，我听到铁路车辆的轧轧之声，一忽儿轻下去了，一忽儿又响起来了，像鹧鸪在扑翅膀，把旅客从波士顿装运到这乡间来。
