Old Nog the heron, flying over the Ram's-horn Pond, saw Greymuzzle among the reeds, for she was the only dark thing in the white wilderness below. She was hiding a solitary cub by curling herself round it, so that her chin rested on her flank. During the storm she had not left the couch of bitten reed and floss; the heat of her body melted the snowflakes. For two days and a night she kept the snow from the blind cub; and when the air was clear, a black frost gripped the waters of the ponds, bound the drifts, and hung icicles from drain and culvert. Then Greymuzzle arose, and called to Tarka over the ice. He answered from the northern horn of the pond. He had kept a fishing hole in the ice, which he bit free as it froze. Fish were hard to see, for the top of the water under the ice was a bad reflector of light to the lower water. As it grew colder, the fish buried themselves in the mud, and when Greymuzzle roved in the brown dim water, she saw only her own vague image following her above. More wildfowl flighted to the estuary, and the cries of birds when the tide was flowing and covering the sandbanks were myriad as the gold flickerings in the night sky. The otters crossed the swift waters to the sandbanks where they were feeding, swimming under the waves and rising to breathe with only their wide nostrils above. Greymuzzle swam up under a duck and seized it, and the change of note in the quacking was heard by the birds, who threw the alarm over the estuary. Thousands of wings whipped jets on the water. The wildfowler creeping up in his narrow boat pulled the trigger of his gun too late--a long red flame sent a blast of shot swishing over the head of Greymuzzle as she dived. She swam to the mouth of the pill with the duck in her jaws, and ate it on an icy litter of twigs and seaweed left by the last high tide. The next night the fishing hole was sealed, and no longer marked by a ring of scales and bones, for the rats and crows had eaten them. Greymuzzle 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 starshine glazed, and mock-trees of the Icicle Spirit grew on the water.
