NOTES ON ESSEX GEOLOGY. 
to “ a considerable outlier (of Bagshot Beds) near Sudbury in 
Suffolk,” and hope that this is not on the Essex side of that 
border-town. 
In his paper on “ Minor British Earthquakes in 1901-1903,” 25 
Dr. C. Davidson records two at Saffron Walden on 1st and 6th 
Nov., 1903, from information given by our member G. Maynard 
(p.541). These w^ere distinct from the “ spurious earthquake,” 
also noted by our member, which was merely loud reports 
caused by the explosion of fireworks or dynamite by an army 
officer. 
The Upper Chalk of Essex is alluded to in Chap, xviii. 
of the third vol. of Jukes-Browne’s Cretaceous Rocks, where it is 
avowed that little is known yet. Unfortunately the sections 
of the Chalk Rock described under Essex on pp. 236, 237, 
except for the two at Great and Little Chesterford, are not in 
our county. A small list of fossils from the Micraster 
coranguinum zone at Saffron Walden is given on p. 239. Our 
southern outcrop, at Grays, is unnoticed. Here again is a 
field for our workers. 
1905 . 
Dr. A. E. Salter’s general paper on Superficial Deposits, 26 
refers to Essex on parts of pp. 24-35 with a description of the 
rock-constituents of the gravels of Epping Forest, and other 
Essex hills eastward, and his conclusion, as far as Essex is 
concerned, is that the Lower Thames, the Lea, etc., must “ be 
of recent formation, geologically speaking,” by which I under¬ 
stand Post Glacial. In a like way are treated the gravels of the 
more northerly parts of Essex, under seven heads, with others, 
reaching across to the south-east, also under seven heads. 
The paper on “ The Relative Ages of the Stone Implements 
of the Lower Thames Valley,” by M. A. C. Hinton and A. S. 
Ivennard, 27 refers of course to our county, though very much 
more to Kent; indeed the paper may be described as general 
and Kentish. 
In part x. of the Final Report of the Royal Commission on 
Coal Supplies reference is made to the deep borings at Weeley 
and Harwich, in the “ statement ” included in my evidence,
