“ moorlog ” or peat dredged from the edges of the Doggei 
Bank, with a report on the plant remains by C. and E. M. 
Reid. 124 
Orwell (J. E. Taylor, E.N., iv., 1890, pp. 90-172). The bed 
of this estuary is occupied by peat 9 feet thick, resting upon 
marl with freshwater shells. 125. 
Foulness, recent marine deposits (W. H. Dalton, E.N., iii.„ 
1889, pp. 239-243; E.N., xv., 1908, pp. 118-125). The second 
paper gives well sections, one of which seems to show as 
much as 75 feet of alluvial deposit. Also E.N., xv., 1909, 
pp. 274-276. 126 
Silting of Navigation Channels off the Essex Coast(E.N ., xi., 1900,. 
p. 271). 127 
Subsidence of Eastern England (W. H. Dalton, E.N., xvi., 1909, 
pp. 96-100, with remarks by H. Laver and S. H. Warren). 
The evidence for a comparatively modern subsidence rests 
mainly upon the foundations of buildings being observed 
upon the tidal flats. This does not seem to me satis¬ 
factory evidence, because foundations are originally below 
the living surface, and when the area becomes invaded by 
the sea, they are often carried still lower by sliding 
[122 ; there are also further remarks on this subject 
under 328] 128 
Encroachment of the Sea (P. Clark, E.N., x., 1898, pp. 355-359). 
Pewit Island (only reclaimed 30 years before) was swamped, 
and the farm house rendered uninhabitable, by the great 
tide of 29 November 1897. [The house still stands, and is 
surrounded by the tides. If the situation had been more 
exposed to the open coast, its foundations, well, cess-pool,, 
etc., might have already furnished apparent evidence of 
subsidence.] Further reports of the devastation of this 
tide are to be found in the same, and the succeeding, 
volume. 129
