Summary

The implements in each are substantially of the same age and character; the matrix of red gravel, in which they rest, is of the same composition; the beds rest directly upon the eroded surface of the chalk or the gault, and are more or less overlain by sands of the same description. But it is incredible that such deposits (if of the same age) , should owe their origin to one and the same river; for if so, in order to reach the higher level, it must have been swollen to the height of 100 feet above the level at Broomhill and Shrub, and extended three miles to the south.

And instead of being blended with, the higher beds (with some exceptions, which are probably attributable to the displacement and reconstruction of the original deposit) , they are found in the lowermost stratum—that which rests immediately upon the Cretaceous or Tertiary beds, and which would be left bare when these became dry land.
It is true that occasionally, although comparatively rarely, implements are found lying above the lowest bed; but this is not inconsistent with the belief that they were originally deposited at the lower level, which I regard as their ordinary or normal position.

Both at Broomhill and Brandon, as well as at Shrub, the implements are found in considerable quantities; I have procured several hundred specimens, sometimes as many as a hundred at a time. Other collectors have also visited the pits, and I have no doubt that there have been at least 1500 specimens procured from them within the last two years. When it is considered how many must escape the notice of the workmen, we may well believe that the valley of the Little Ouse is as prolific of these objects as that of the Somme, if not more so.
