Hydrologist: The trust credits the blocking of the Fenmoor drains with bringing the water table back to within ten centimetres of the surface. But those ditches had silted shut years earlier, so what raised the table was the felling of the conifer belt, which drew off more water than the ditches ever carried. Cardle, the next bog along, was blocked just as thoroughly, has no conifer belt, and has not risen.

The hydrologist's reasoning is most vulnerable to criticism on the grounds that it

Ainfers that the felling raised the water table from its having come earlier than the recovery, when the order of two events settles nothing about which produced the other

Blets evidence that tells against the trust's account stand as evidence for an account of its own, when what it offers need not exclude some further influence on the table

Csets the trust's account aside without establishing how much water the Fenmoor ditches carried before they silted, a quantity no argument about a bog can now supply

Dtakes the ten-centimetre figure on trust, when it comes from the very party whose work is in dispute

Etreats Cardle's failure to recover as support for its own account, when a bog with no conifer belt to fell could not have shown that account's effect either way
