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), T halictrum flavum (Meadow Rue), Hypericum quad- 
rangulum , Artemisia vulgaris, Scrophularia ac[uatica, 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. lutevs, but is now stated to be M. langsdorffii y 
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, Booking, Braintree. 
Mr. Alfred D. Phelp, Rosebank, 63, Station Road, Chingford.
