“Deep down here by the dark water lived old
Gollum, a small slimy creature. I don’t know
where he came from, nor who or what he was. He was Gollum — as dark as darkness, except for two big round pale eyes in his thin face. He had a little boat, and he rowed about quite quietly on the lake; for lake it was, wide and deep and deadly cold. He paddled it with large feet dangling over the side, but never a ripple did he make. Not he. He was looking out of his pale lamp-like eyes for blind fish, which he grabbed with his long fingers as quick as thinking. He liked meat too. Goblin he thought good, when he could get it; but he took care they never found him out. He just throttled them from behind, if they ever came down alone anywhere near the edge of the water, while he was prowling about. They very seldom did, for they had a feeling that something unpleasant was lurking down there, down at the very roots of the mountain. They had come on the lake,
when they were tunnelling down long ago, and they found they could go no further; so there their road ended in that direction, and there was no reason to go that way — unless the Great Goblin sent them. Sometimes he took a fancy for fish from the lake, and sometimes neither goblin nor fish came back.”
