When the ponds were firmly frozen,they afforded not only new and shorter routes to many points,but new views from their surfaces of the familiar landscape around them.When I crossed Flint's Pond,after it was covered with snow,though I had often paddled about and skated over it,it was so unexpectedly wide and so strange that I could think of nothing but Baffin's Bay.The Lincoln hills rose up around me at the extremity of a snowy plain,in which I did not remember to have stood before;and the fishermen,at an indeterminable distance over the ice,moving slowly about with their wolfish dogs,passed for sealers or Esquimaux,or in misty weather loomed like fabulous creatures,and I did not know whether they were giants or pygmies.I took this course when I went to lecture in Lincoln in the evening,travelling in no road and passing no house between my own hut and the lecture room.In Goose Pond,which lay in my way,a colony of muskrats dwelt,and raised their cabins high above the ice,though none could be seen abroad when I crossed it.Walden,being like the rest usually bare of snow,or with only shallow and interrupted drifts on it,was my yard where I could walk freely when the snow was nearly two feet deep on a level elsewhere and the villagers were confined to their streets.There,far from the village street,and except at very long intervals,from the jingle of sleigh-bells,I slid and skated,as in a vast mooseyard well trodden,overhung by oak woods and solemn pines bent down with snow or bristling with icicles.
For sounds in winter nights,and often in winter days,I heard the forlorn but melodious note of a hooting owl indefinitely far;such a sound as the frozen earth would yield if struck with a suitable plectrum,the very lingua vernacula of Walden Wood,and quite familiar to me at last,though I never saw the bird while it was making it.I seldom opened my door in a winter evening without hearing it;Hoo hoo hoo,hoorer hoo,sounded sonorously,and the first three syllables accented somewhat like how der do;or sometimes hoo hoo only.One night in the beginning of winter,before the pond froze over,about nine o'clock,I was startled by the loud honking of a goose,and,stepping to the door,heard the sound of their wings like a tempest in the woods as they flew low over my house.They passed over the pond toward Fair Haven,seemingly deterred from settling by my light,their commodore honking all the while with a regular beat.Suddenly an unmistakable cat owl from very near me,with the most harsh and tremendous voice I ever heard from any inhabitant of the woods,responded at regular intervals to the goose,as if determined to expose and disgrace this intruder from Hudson's Bay by exhibiting a greater compass and volume of voice in a native,and boo-hoo him out of Concord horizon.What do you mean by alarming the citadel at this time of night consecrated to me?Do you think I am ever caught napping at such an hour,and that I have not got lungs and a larynx as well as yourself?Boo-hoo,boo-hoo,boo-hoo!It was one of the most thrilling discords I ever heard.And yet,if you had a discriminating ear,there were in it the elements of a concord such as these plains never saw nor heard.
I also heard the whooping of the ice in the pond,my great bed-fellow in that part of Concord,as if it were restless in its bed and would fain turn over,were troubled with flatulency and bad dreams;or I was waked by the cracking of the ground by the frost,as if some one had driven a team against my door,and in the morning would find a crack in the earth a quarter of a mile long and a third of an inch wide.
Sometimes I heard the foxes as they ranged over the snow-crust,in moonlight nights,in search of a partridge or other game,barking raggedly and demoniacally like forest dogs,as if laboring with some anxiety,or seeking expression,struggling for light and to be dogs outright and run freely in the streets;for if we take the ages into our account,may there not be a civilization going on among brutes as well as men?They seemed to me to be rudimental,burrowing men,still standing on their defence,awaiting their transformation.Sometimes one came near to my window,attracted by my light,barked a vulpine curse at me,and then retreated.
