PROCEEDINGS, 
Visit to the Watford G-as Works, 2nd April, 1910. 
The construction of a new retort house having necessitated 
excavation of the alluvial deposits formed by the River Colne 
when flowing at a higher level than now, and a good section 
being exposed, this visit was arranged by Mr. Daniel Hill, 
a Director of the Watford Gas Works, to enable members of the 
Society to examine that section. 
The beds seen were, in descending order: Alluvium, consisting 
of brown clay full of shells, 1 ft.; peaty clay, dark above and 
black below, 1 ft. 2 ins.; grey marl with shells, 1 ft. 4 ins.; 
gravel seen to a depth of 8 feet. The top of the beds is 176 ft. 
above Ordnance Datum, and 3 or 4 feet above the present level 
of the Colne. 
In the course of the excavations the following mammalian 
remains have been found:—Part of a human skull and thigh¬ 
bone, ox ( Bos taurus), horse ( Equus caballus), red deer 
(Gervus elaphus), roebuck ( Capreolus caprsea ), sheep ( Ovis 
aries), and dog ( Canis familiaris) . These have been identified 
by Mr. E. T. Newton, E.R.S., who considers that they do not 
indicate any great antiquity, probably not dating so far back as 
Roman times. 
In the higher alluvial shell-bed the following species of 
freshwater Mollusca were collected by Mr. Charles Oldham:— 
Limnsea pereger (Mull.), L. palustris (Mull.), L. truncatula 
(Miill.),T/. stagnalis (Linn.), Valvatapiscinalis (Mull.), F. cristata 
(Mull.), Pisidium casertanum (Poli), and P. gassiesianum, 
Dupuy. 
The visit concluded with an inspection of the Gas Works, and 
tea kindly provided by the Directors.
