in any of the pits belonging to this section, but the water, as 
a whole, was flowing towards Hunton Bridge. In a pit excavated 
beyond the railway bridge, the incoming current seemed to flow 
obliquely across the line of excavations, and towards the Biver 
Gade from the higher ground on the eastern side of the valley. 
In a few of the pits the flints in the ballast were green-coated, 
suggesting that they were derived from the bottom bed of the 
Beading Beds; on the other hand, the ballast drawn from most of 
the pits was of a reddish-brown colour. 
Fig. 27.— Section in the Gade Yalley, near Hunton Bridge. Scale 24 ft. = 1 in. 
A thin bed of light grey clay, similar to that found in the 
excavations at the Watford Gasworks, described in Yol. XII, 
Part 1, of the ‘Transactions of the Herts Nat. Hist. Soc.,’ rested 
above the ballast. No fossils were found in this clay. 
The beds, denoted in Pig. 27 by means of the reference numeral 
3, are very complicated, and consist chiefly of loam, which is very 
flinty in the upper parts of the beds. In that part of the section 
in which the ballast and light-grey clay occur, the loam is made 
up of three beds, an upper light-brown flinty loam, a middle dark- 
brown loam with only a few flints, and a lower thick sandy loam 
with a few flints. At the northern end of the excavations the
