White Mare's Tail, in case you don't know, is the force that comes out of the fell near top of Lang Neb. That's the steep fell between us and Danby. It's marked "Long Denderside" on maps, but no one local ever calls it owt but Lang Neb, that's because if you look at it with your head on one side, it looks like a nose, gradually rising till it drops down sudden to Black Moss col on the edge of Highcross Moor. On the other side it rises up again, but more gradual, to Beulah Height above our farm. There's two little tops up there and because they look a bit like a mouth, some folk call it the Gob, to match the Neb opposite. But Mrs. Winter said we shouldn't call it owt so common when its real name was so lovely, and she read us a bit from this book that Beulah comes into. Joss Puddle said it were dead boring and he thought the Gob were a much better name. But I liked Beulah 'cos it were the same as our farm and besides it sort of belonged to us, seeing as my dad had the fell rights for his sheep up there and he kept the fold between the tops in good repair, which Miss Lavery said was probably older than our farmhouse even.

Any road, no one could deny our side of the valley were much nicer than Lang Neb side, which was really steep with rocks and boulders everywhere. And in the rainy season, while there'd be becks and falls streaking all of the hillsides, on the Neb they just came bursting straight out of fell, like rain from a blocked gutter. Old Tory Simkin used to say there were so many caves running through the Neb, there was more water than rock in it. And he used to tell stories about children falling asleep in the sunshine on the Neb, and being taken into the hill by nixes and such, and never seen again.

But he stopped telling the stories when it really started happening. Children disappearing, I mean.

Jenny Hardcastle were the first. Holidays had just started and we were all splashing around in Wintle Pool where White Mare's Tail hits fell bottom. Usually little ones got told off about playing up there, but now the big pool were so shallow, even the smallest could play there safe.
