referred to (Essex Naturalist, I., 39). In 1899 Mr. Miller
Christy published "Notes on an Alluvial Deposit in the Cann
Valley, with a list of the Mollusca," to which notes were added
by Mr. Dalton (Ibid. III., 1), and Mr. R. W. Christy a
paper, "Notes on the Geology of the District around Chelms-
ford" which has already been referred to in connection with the
lists of Mollusca (Ibid. III., 171). Mr. Dalton dealt with the
Geology of Fowlness at our Southend meeting in 1889 (Ibid.
III., 239) and the following year he published his "Notes of
Geological Rambles in the Braintree District in connection with
the Easter Excursion of the Club" (Ibid. IV., 79). As a
contribution to local physiography the silting up of the River
Roding, as reported upon by the County Surveyor, has been
duly noted in our pages (Ibid. IV.,94).
Among recent workers in Essex geology Mr. H. W.
Monckton must be mentioned as a contributor of valuable papers
to the Essex Naturalist. His first communication on the
Boulder Clay in Essex was published in 1890 (Essex Natural-
ist, IV., 199). At a field meeting on July nth, 1891, he read
"Notes on the Glacial Formation near Chelmsford" (Ibid. V.,
191); in 1893 we published his "Geological Notes in the Neigh-
bourhood of Ongar" (Ibid. VII., 87) and the same year his
paper read at the Barking Side meeting on July ist "On the
Gravels near Barking Side, Wanstead, and Walthamstow"
(Ibid., 115). We have also reaped the benefit of the presence of
that zealous worker at Felstead, Mr. J. French, who in 1891
called attention to the occurrence of Westleton Beds in North-
west Essex (Ibid. V., 210), and in 1892 contributed a paper "On
some Plateau Deposits at Felstead and Stebbing" in which he
discusses some interesting points in Post-Glacial Geology (Ibid.
VI., 132). Our late member, Mr. T. Hay Wilson, also has
given us the benefit of his local vigilance. In 1893 he published
his notes on the gravels of Epping Forest, being the result of his
observations of sections at Copt Hall, High Beach, Chingford
and Buckhurst Hill (Ibid. VII., 74), and four years later he gave
us a note on sections in the Lea Valley exposed at South
Tottenham during the construction of the new reservoirs (Ibid,
X., no). The question of the occurrence of coal under Essex
has, on account of its possible economic bearings, naturally
engaged considerable attention and given rise to much contro-
versial writing. The Rev. A. Irving published a newspaper
