478 CONFERENCE OF DELEGATES 
Committee included the following localities—chiefly on account of the 
necessity for preservation of birds, insects and plant life—Royston Heath, 
Cavenham and Tuddenham Heaths, Mildenhall; Bradfield St. Clare, 
Monk Park Wood; Blythburgh, Foxburrow Wood and part of the sur- 
rounding heath and fen; Martlesham Common ; part of the erstwhile 
estuary of the river Waveney ; and Horsey Mere, Yarmouth. 
In considering such reserves, however, we may be contemplating park- 
like areas (excluded from this address) rather than sites and objects of 
scientific interest. But that is only a question of scale. We can, for 
example, urge that a small area at least of Breckland shall be free from 
afforestation (and I understand that there is a likelihood that Cavenham 
Heath will be saved for science), to preserve its peculiar ecology, and such 
historical features as infields and outfields, its geological character, and 
archeological interest. On archzological grounds I would make a strong 
plea for the preservation of the site known as High Lodge, famous for the 
discovery there of an advanced Clactonian industry of early man. Not 
far from Mildenhall also, the ‘ Drove Road’ runs through part of southern 
Norfolk to join the well-known Peddar’s Way. ‘The ‘road’ is an ancient 
trackway, in parts grassy, dating from the Bronze Age or even earlier times. 
Part of it could with advantage be preserved. 
It would be a simple matter to prepare a list of sites (as distinct from large 
areas) in East Anglia which should be preserved on account of their geo- 
logical and archzological interest, for the district has long been a Mecca 
for students of Pliocene and Pleistocene geology and the records of pre- 
historic man. A real danger is imminent here that material will be for- 
ever lost to science once the builder gets to work. From many examples, 
I choose only a few as representative. ‘The small outlier of the Oakley 
horizon of the Waltonian zone of the Red Crag near Manningtree is probably 
only a few hundred acres in extent. Yet from this locality the late F. W. 
Harmer of Norwich collected more than 600 species of mollusca, including 
many rare northern forms which, migrating into the area in Pliocene times, 
are regarded as the heralds of the oncoming Great Ice Age. This small 
outcrop of crag should be kept for future generations to study. Again, 
exposures of shelly Norwich Crag are now very uncommon. In the whole 
of the area, 800 square miles in extent, where the Norwich Crag is believed 
to be present, I know of only two localities, those at Bramerton and Thorpe, 
where characteristic fossils are abundant. The latter has yielded in recent 
years the richer fauna, but the sections are now obscure, and the pit is being 
filled in with rubbish. Both these sites should be carefully preserved. A 
further Pliocene section which should undoubtedly be preserved is the classical 
exposure at Sutton, near Woodbridge, where Prestwich described a reef 
of Coralline Crag with Red Crag banked against it, and a Mytilus bed in 
place. Still another classical geological section is that of the type-locality 
of fossiliferous Chillesford Crag, at the Chillesford Church pit—the only 
example of the deposit now known. For some years the exposure has steadily 
become more obscure, but there is still time to save the site. 
So long ago as 1797 the first British palzolithic implements were recorded 
in Britain by John Frere from Hoxne, near the county boundary of Suffolk 
and Norfolk. Later investigations, in part by Research Committees of the 
British Association, have demonstrated the great geological and archzo- 
logical interest of the succession of ancient lake-deposits and early human 
industries at this famous locality, with the result that it has proved to be 
unique in Britain on account of the detailed evidence that it affords of inter- 
glacial climatic fluctuations. The lake-like area is of limited extent, and 
its uppermost deposits are being slowly but continuously removed for brick-
