It will at once be observed that these assessments are, as nearly as possible, on one half the scale of those we met with in Cambridgeshire and Northamptonshire. But this must be taken in conjunction with the fact that the Devon and Cornwall assessments are altogether peculiar. 'In Devon and Cornwall, where the scope of the gheld-hide was enormous, it was necessary to introduce another quantity, intermediate between the virgate and the acre. This was the Ferndel or Ferdingdel, to wit, the fourth part of the next superior denomination, the fourth part of the virgate.'[116] One might at first sight be tempted to suggest that the hide was in these two counties a term of higher denomination when we find Manor after Manor assessed at a fraction of a hide, while in Cornwall the 'acra terræ' was clearly a peculiar measure.[117] Yet in some Manors adjacent to Exeter or to the neighbouring coast the assessment is much less abnormally low, though even there moderate. There is much scope, here also, for intelligent local research, although we may conclude, from the evidence of the Pipe Rolls, that the hide represented the same unit here as elsewhere, as it would seem did the Devonshire Hundred, in spite of its singularly low average assessment. Indeed, it represented a larger, not a smaller, area than usual. I shall deal with this phenomenon below, and endeavour to explain its significance. For the present it is only necessary to insist on the evidence that the Hundreds afford of assessment on the five-hide system. Indeed, though I definitely advance the suggestion that the assessment was, in the first instance, laid upon the Hundred itself, and that the subsequent assessment of its Vills and Manors was arrived at by division and subdivision, the truth or falsehood of this theory in no way affects the indisputable phenomenon of the five-hide unit. On the prominence of that unit I take my stand as absolute proof that the hide assessment was fixed _independently of area or value_, and that, consequently, all the attempts that have been made by ingenious men to discover and establish the relation which that assessment bore to area, whether in Vill or Manor, have proved not only contradictory among themselves, but, as was inevitable, vain.
