The last of these London records with which I have here to deal is the so-called “Hidagium” of Middlesex.[524] The explanation of its thus appearing among documents relating to the administration of London is that when London and Middlesex were jointly “farmed” by the citizens, the sheriffs answered jointly for the ‘Danegeld’ of Middlesex and the corresponding _donum_ or _auxilium_ of London. Here therefore we find these two levies side by side as on the Pipe Rolls. But though the latter was levied from the city when Danegeld was levied from the shire, it was in no way connected with hidation, but consisted of arbitrary sums payable by the principal towns. Prof. Maitland, therefore, is mistaken when, in his great work, ‘Domesday Book and Beyond,’ he makes a solitary reference to our MS., as implying that London “seems to have gelded for 1,200 hides” (p. 409). He has here confused the assessed hidage of boroughs with the arbitrary _donum_ or _auxilium_. This is shown by comparing the latter, as given by himself (p. 175), with the ascertained hidage of towns and the payments its sum would involve. hides. [geld.] donum.

It is, of course, just possible that the obsolete figure was retained, as a protest, on this list; but it is far more probable that what we have here is a copy _temp._ John of an earlier document, perhaps not later than the middle of the 12th century.[525] HIDAGIUM COMITATUS TOCIUS MIDDLESEXE.
