And when the shining twitter ceased, I walked to the pond, and again I sought among the reeds, in vain; and to the pill I went, over the guts in the salt grey turf, to the trickling mud where the linnets were fluttering at the seeds of the glasswort. There I spurred an otter, but the tracks were old with tides, and worm castings sat in many. Every fourth seal was marred, with two toes set deeper in the mud. They led down to the lap of the low water, where the sea washed them away. THE LAST YEAR CHAPTER ELEVEN Bogs and hummocks of the Great Kneeset were dimmed and occluded; the hill was higher than the clouds. In drifts and hollows of silence the vapour passed, moving with the muffled wind over water plashes colourless in reflection. Sometimes a colder waft brought the sound of slow trickling; here in the fen five rivers began, in peat darker than the otter that had followed one up to its source. Broken humps, rounded with grey moss and standing out of a maze of channers, made the southern crest of the hill. In the main chamber, below banks of crumbling peat, lay water dark-stained and almost stagnant. The otter walked out and lifted his head, sniffing and looking around him. Drops from his rudder dripped into the water and the stirred fragments of peat drifted slowly as they settled. The river's life began without sound, in the darkness of peat that was heather grown in ancient sunlight; but on the slope of the hill, among the green rushes, the river ran bright in spirit, finding the granite that made its first song. Tarka climbed up one of the humps of grey club moss and trod in its centre a bed soft and warm, yet cool for the paw thrust among the long, tight-growing fronds. The moss grew on and over a bush of heather, whose springy stems yielded to his curled body. He had travelled from the estuary, sleeping by day in riverside holts and marshes and feeding at night; remembering nothing, because the moor was unfamiliar to his nose and ears and eyes. When his paw ached, he licked it. It had been a happy journey up the river swollen with snow water, hunting fish and playing with sticks and stones, while mating owls called through the darkness of valleys.
