These beds are worked for the celebrated Bockland bricks, and clearly underlie chalky Boulder Clay. For some time after seeing these beds I was in doubt about their equivalents in other parts of the country examined by me, and about their position in the geological scale, and from not having at first seen their base I thought it even possible that they might be of Eocene age. During a visit to Brandon and Thetford, under the guidance of my colleague Mr. Skertchly in 1877, I was much struck with the similarity of the clays he there termed the "Brandon Beds," with the blue and grey brickearths of Rockland and Surlingham. On my return to Norwich I took the first opportunity of revisiting these sections, and was more than ever struck with their similarity. Having communicated these notions to Mr. Skertchly he came over and visited all the sections with me, and was equally struck with the many and striking resemblances exhibited. In the present state of the evidence this correlation is only suggested: no palaeolithic implements have been found in the beds at Surlingham and Bockland. It may be well to note here that at Surlingham there is a distinct laminated brickearth (identified by some as " Chillesford Cluy ") developed in the Crag ...
