Abstract
Two of the largest districts which are most constantly flooded are, perhaps, Oxford and “The Plain of York.” The same cause floods both these districts, namely, what Mr. Mackintosh has called “Colonel Greenwood's hard gorge and soft valley theory.” Both these districts have been worn down by rain and rivers in the soft oolitic strata; and the Humber and the Thames have ever had, and have now, to force outlets through comparatively hard chalk gorges. The rain-flood, waters, checked at these gorges, overflows and deposits alluvium behind the gorges. The same takes place in the soft strata of the Weald, behind the nine comparatively hard chalk gorges of the North and South Downs.
