But we have not yet exhausted the valuable evidence of _Domesday_. The land in the Forest district is rented at much less than in other parts of Hampshire, showing that it was therefore poorer, and not only the land, but the mills. Further—and this is of great importance, as so thoroughly overthrowing the common account—we find in that portion of the survey which comes under the title, “In Novâ Forestâ et circa eam,” only two churches mentioned, one at Milford, and another at Brockenhurst, in the very heart of the Forest. Both stand to this hour, and prove plainly by their Norman work that William allowed them to remain. Such is the evidence which _The Chronicle_ and the short examination of _Domesday_ yield. The country itself, however, still more plainly proves the bias of the Chroniclers. The slightest acquaintance with geology will show that the Forest was never fertile, as it must have been to have maintained the population which filled so many churches.[28] Nearly the whole of it is covered with sand, or capped with a thick bed of drift, with a surface-soil only a few inches deep, capable of naturally bearing little, except in a few places, besides heath and furze. On a geological map we can pretty accurately trace the limits of the Forest by the formation. Of course, in so large a space, there will be some spots, and some valleys, where the streams have left a richer glebe and a deeper tilth.[29] But the Chroniclers, by their very exaggeration, have defeated their own purpose. There is in their narration an inconsistency, which, as we dwell upon it, becomes more apparent. We would simply ask, where are the ruins of any of the thirty or fifty churches, and the towns of the people who filled them? Why, too, did not the Chroniclers mention them specifically? Why, further, if William pulled down all the churches, are the only two, at Brockenhurst and Milford, recorded in _Domesday_,[30] still standing with their contemporary workmanship? Why, too, is Fawley church, with its Norman doorway, and pillars, and arches, formerly, as we know from another portion of _Domesday_, in the Forest, remaining, if all were destroyed? And why, last of all, if the inhabitants were exterminated, was a church built at Boldre, in the very wildest part of the Forest, immediately after the afforestation, and another at Hordle?[31]
