muzzle was scraping at a fish frozen in the ice when the sheet whanged and whined and creaked, then boom!, a crack ran across it, and water spirted in the fissure. When it was still, Orion was reflected there, with the red and green flashes of Sirius; but as Greymuzzle peered the star-shine glazed, and mock-trees of the Icicle Spirit grew on the water.
The cold sharpened. To the estuary came sanderlings in white winter dress, who ran at the tide-line like blown sea-foam. Snow buntings followed, and went south with them. The flatfish swam to warmer water beyond the bar, and often when the otters dived in the estuary they rose empty-mouthed to the surface, except perhaps for a green crab. Old Nog the heron grew so thin that he looked like a bundle of grey flags stripped by wind and clinging to two reeds. His inland fishing ponds were frozen, most of the streams ran under plates of ice, and the only food he could spear was to be found at low tide in the pools of the Shrarshook Ridge, where gravel had been dug.
The pans and plains of the Burrows were crossed by a thousand tracks, the prints of larks, finches, wagtails, crows, and gulls; the presses of weasels, rabbits, and stoats; the pads of badgers and foxes; the triple toes of herons and bitterns, like the veining of leaves. Many of the smaller birds were so weak they could not fly, and their bodies were eaten by rats and weasels, which were eaten by the larger owls and hawks.
Other otters from the Two Rivers came down to the estuary, some of them cubs of ten or
