The ragged quilt of snow had slipped from the shoulders of the slopes, the gray face of the maple swamp showed a flush of warmth, and the air, out of the south to-day, breathed life, the life of buds and catkins, of sappy bark, oozing gum, and running water--the life of spring; and through the faintly blending breaths, as a faster breeze ran down the hills, I caught a new and unmistakable odor, single, pointed, penetrating, the sign to me of an open door in the wood-lot, to me, indeed, the Open Sesame of spring. “When does the spring come? And who brings it?” asks the watcher in the woods. “To me spring begins when the catkins on the alders and the pussy-willows begin to swell,” writes Mr. Burroughs, “when the ice breaks up on the river and the first sea-gulls come prospecting northward.” So I have written, also; written verses even to the pussy-willow, to the bluebird, and to the hepatica, as spring’s harbingers; but never a line yet to celebrate this first forerunner of them all, the gentle early skunk. For it is his presence, blown far across the February snow, that always ends my New England winter and brings the spring. Of course there are difficulties, poetically, with the wood-pussy. I don’t remember that even Whitman tried the theme. But, perhaps, the good gray poet never met a spring skunk in the streets of Camden. The animal is comparatively rare in the densely populated cities of New Jersey. It is rare enough here in Massachusetts; at least, it used to be; though I think, from my observations, that the skunk is quietly on the increase in New England. I feel very sure of this as regards the neighborhood immediate to my farm. This is an encouraging fact, but hard to be believed, no doubt. I, myself, was three or four years coming to the conviction, often fearing that this little creature, like so many others of our thinning woods, was doomed to disappear. But that was before I turned to keeping hens. I am writing these words as a naturalist and nature-lover, and I am speaking also with the authority of one who keeps hens. Though a man give his life to the study of the skunk, and have not hens, he is nothing. You cannot say, “Go to, I will write an essay about my skunks.” There is no such anomaly as professional nature-loving, as vocational nature-writing. You cannot go into your woods and count your skunks. Not until you have kept hens can you know, can you even have the will to believe, the number of skunks that den in the dark on the purlieus of your farm.
