The pickerel of Walden! when I see them lying on the ice, or in the well which the fisherman cuts in the ice, I am always surprised by their rare beauty, as if they were a fabulous fish, they are so foreign to the streets, or even the woods; handsome as flowers and gems, golden and emerald, - a transcendent and dazzling beauty which separates [them] by a wide interval from the cadaverous cod and haddock, at least a day old, which we see. They are as foreign as Arabia to our Concord life, as if the two ends of the earth had come together. These are not green like the pines, or gray like the stones, or blue like the sky; but they have, if possibly, to my eye, yet rarer colors like precious stones. It is surprising that these fishes are caught here. They are something tropical. That in this deep and capacious spring, far beneath the rattling teams and chaises and tinkling sleighs that travel the Walden road, this great gold and emerald fish swims! They are true topazes, inasmuch as you can only conjecture what place they came from. The pearls of Walden, some animalized Walden water. I never chanced to see this kind of fish in any market. With a few convulsive quirks they give up their diluted ghosts.
