Excerpt from The Philosophical Magazine, or Annals of Chemistry, Mathematics, Astronomy, Natural History, and General Science, Vol. 8: July December, 1830 Availing myself last year of the favourable state of the weather about midsummer, I undertook, and within three weeks finished, the Trigonometrical Survey of the Hills of Swaledale, a valley north of, and adjoining that of Wensleydale. It was originally intended to have placed signals on the principal hills only (the peculiar features of the dale rendering impracticable the plan adopted in the preceding survey); yet the temptation in the course of the operations, of marking for measurement such others of minor note as were situated on our route, could seldom be resisted. The exceptions had at length become so reduced in number, that the deficient signals would have been supplied, and the survey made complete for hills of both descriptions, had not numerous indications of approaching tempestuous weather urged the propriety of commencing the observations without further delay. As an additional motive to dispatch, it was noticed during the progress of the measurements that two of the more distant signals had successively disappeared; one of which, on West Stonesdale Moor, having been observed from one station only, was totally lost to the survey. The other, on the Nine Standards Hill, had most probably been demolished by a jealous shepherd or keeper, acting under the impression that it had been set up in opposition to the adjacent nine standards or boundary marks between Westmoreland and Yorkshire, whence the fell derives its name.
