Another class of exceptions is accounted for by the tendency of both texts, as we have seen, to enter a virgate too much or too little, and to confuse virgates with their fractions. Thus at 'Litlingetona' our figures give us a virgate in excess of the assessment, while at 'Bercheham'[80] and again at 'Witlesforde' we have a virgate short of the amount. At 'Herlestona' we have, similarly, half a virgate too much, and 'Kingestona' half a virgate (15 acres) too little. Lastly, at 'Wicheham', the aggregate of the figures is a quarter of a virgate short of the amount. A third class of these exceptions is due to the frequent omission in the I.C.C. of estates belonging to the king. Thus at Wilbraham it records an assessment of 10 hides represented only by two estates of four hides apiece. But on turning to Domesday (i. 189 _b_) we read: 'Wilborham dominica villa regis est. Ibi ii. hidæ.' The missing factor is thus supplied, and the apparent discrepancy disposed of. So, too, at 'Haslingefelda' (Haslingfield), where the I.C.C. accounts only for twelve hides and three virgates out of an assessment of twenty hides. Domesday here, again, supplies the missing factor in a royal Manor of seven hides and a virgate. We thus obtain, instead of an exception, a fresh illustration of our rule. _Haslingfield_ _H._ _V._ _A._ Rex 7 1 Picot 4 3 Count Alan 1 1/2 The same 1/2 Geoffrey de Mandeville 5 Guy de Raimberccurt 1 1 3 Count Alan 12 ---- ----- ---- 20 0 0 Domesday omits altogether, so far as I can find, the holding of Guy, an omission which would upset the whole calculation. But, in the case of Isleham, the apparent exception is due to the I.C.C., not to Domesday Book. Its assessment, in that document, is given as four hides. But the aggregate of its Manors, as there recorded, gives us an assessment of three hides _plus_ eighty acres. Here any one who was rash enough to argue from a single instance (as Mr Eyton and Mr Pell were too apt to do) might jump at the conclusion that the hide must here have been of eighty acres. Yet Domesday enables us to collect all the constituents of the 'Vill', among them the king's estate, here again omitted. The real figures, therefore, were these: _H._ _V._ _A._ _D.B._ The King 6 0 40 i. 189 _b._ Bishop of Rochester 1-1/2 0 20 i. 190 _b._ Hugh de Port 1-1/2 0 20 i. 199 _a._ Earl Alan 40 i. 195 _b._ ----- --- ---- 10 0 0
