20 THE ESSEX FIELD CLUB.
include chalk pebbles, Red Chalk, very large Chalk flints (some unrolled),
sarsens, Hertfordshire-puddingstone, fossiliferous Jurassic limestones,
many Jurassic Septaria, Bunter quartzites, quartz rock, Millstone Grit,
various sandstones, dark chert, &c., beside Jurassic gryphaeas and chalk
echinoderms. Few igneous rock fragments occur, but a large boulder
of "Norwegian granite" from this gravel is preserved in the garden of
Mr. W. Skipp, and this was examined.
It is noteworthy that Mr. G. Barrow records (in Proc. Geol. Ass. xxv.,
1914, p. 116) a large block of granite "almost certainly Scandinavian,"
from the large pit at Hertford to the S. of the Ware Road, on the opposite
bank of the river Lea, in similar Glacial Drift.
It was noticed with interest that many sand martins have made their
nests in the sandy layers of the pit-face.
Rejoining the "Salisbury," the voyage down stream from Ware was
made under Mr. Tween's capable guidance, who pointed out the many
places and objects of interest which were passed. A detour was made
up the river Stort for the purpose of inspecting Roydon Lock, which was
then under reconstruction.
During the day the amateur botanists present, under Miss Willmott's
and Miss Lister's guidance, gathered and determined very many interesting
plants on the river's banks and in the adjoining meadows. The reporter
remembers, amongst many others, the abundance of Galium palustre
and the masses of Hemp Agrimony (Eupatorium cannabinum) on the
rill banks, with purple and yellow Loosestrife (Lythrum salicaria and
Lysimachia vulgaris), Thalictrum flavum (Meadow Rue), Hypericum quad-
rangulum, Artemisia vulgaris, Scrophularia aquatica, Medicago maculata
and Carduus tenuiflorus in the water-meadows. The interesting alien,
Erigeron canadensis, occurred in the gravel-pit at Ware, and on the banks
of the Stort River, and on the banks of the Lea near Rye House the
yellow Mimulus was again seen in great and very handsome abundance.
It used to be called M. luteus, but is now stated to be M. langsdorfjii,
Dow., and its native home North America (see report of the voyage on
the Lea on 15th June 1899, Essex Naturalist, vol. xi. p. 138).
High tea was taken at the "Crown Hotel," Broxbourne Bridge, rather
late, so that some members were compelled to take train for London at
the station. Others continued the voyage in the barge as far as Waltham
Abbey, which was not reached until 10.30 p.m.
After tea a meeting was held, under chairmanship of the President,
when cordial votes of thanks were passed to all who had contributed to
rendering the day a very pleasant and instructive one. The following
were duly elected members of the Club:—
Miss Pamela Adeane, 34, Cadogan Square, London, W.
Miss Emma Brown, 138, Stamford Hill, N.
Mr. Alfred Hills, The Old House, Bocking, Braintree.
Mr. Alfred D. Phelp, Rosebank, 63, Station Road, Chingford.
POSTPONEMENT OF MEETING.
A meeting had long been fixed for the purpose of visiting the Colne
Oyster Fisheries, under the auspices of the Fisheries Committee of the
