Field Meeting, 23rd July, 1910. 
WATFORD. 
This meeting was held in conjunction with the Geologists’ 
Association and was under the direction of Mr. Henry 
Kidner, F.G.S., from whose report of it the following account 
is condensed. 
The object of the meeting was chiefly to examine certain 
deposits of alluvium, peat, and gravel of the River Colne. The 
Watford Gas Works, the grounds of Bushey Hall, and the 
Five Arches were visited, and then a traverse was made of 
the widening of the Rickmansworth branch line of the London 
and North-'Western Railway, and of the new extension to Croxley. 
At the Gas Works was shown an interesting collection of 
fossil bones of the ox, horse, red deer, roebuck, sheep, and dog, 
obtained during excavations in the alluvium and peat there, and 
also shells of several species of land and fresh-water Mollusca 
found in the peaty alluvium by Mr. Oldham. 
To the west of Bushey Hall, in a small wood, a pit was seen 
exposing about 10 feet of stratified gravel, with piping which had 
caused zigzag faulting. The gravel is generally much disturbed 
by the dissolution of the underlying chalk. It consists chiefly 
of angular and sub-angular flints, flint-pebbles, unworn flints, 
quartzite-pebbles, sandstone, and quartz. Radiolarian chert, 
veined tourmaline quartzite, and a piece of decomposed igneous 
rock, possibly rhyolite or rhyolitic ash, were also found. 
At the Five Arches gravel was seen a few feet from the Colne, 
4 or 5 feet above its present level and forming a well-marked low 
terrace, doubtless continuous with the gravel at the Gas Works. 
Looking across the golf-links the Bushey Hall gravel was seen 
to form a higher terrace. 
From High Street Station the walk was continued under the 
guidance of Mr. J. H. Woodhead, Engineer to the Railway 
Company, along the new widening of the line to Rickmansworth 
and the branch now being made to Croxley. It was noticed that 
immediately below Watford the gravel is all on the north or 
right side of the Colne, suggesting its former more northward 
course, the river having cut its way southwards down to its 
present level. 
Between Pest House Lane and Holywell, alternating beds of 
gravel and peat have been found beneath the river, in descending 
order: gravel 2 ft., peat 2 ft. 6 ins., gravel 1 ft. 6 ins., peat 9 ins., 
gravel 3 ft.; total 9 ft. 9 ins. In the peat were found, in the
