The Elfin Hill (Story Time, Episode 89)

A few large lizards were running nimbly about in the clefts of an old tree; they could understand one another very well, for they spoke the lizard language.
“What a buzzing and a rumbling there is in the elfin hill,” said one of the lizards; “I have not been able to close my eyes for two nights on account of the noise; I might just as well have had the toothache, for that always keeps me awake.”
