228 Mr. G. J. Hinde’s Notes on the 
northwards includes Waddon, Beddington, and Mitcham Com- 
mon to the Thames valley. This depression has been partially 
filled by an extensive sheet of gravel which has been carried 
into it from the chalk district to the south. 
On the eastern slopes of the Tertiary beds, within the bounds 
of Croydon, there is a well-marked upper terrace of gravel, at 
levels of 180-200 ft. above O.D., or from 40 to 50 ft. above the 
valley of Old Town below. Starting from St. Peter’s Church, 
South Croydon, it continues northwards along St. Peter’s Road, 
‘Park Lane, Katherine Street, to the High Street, George Street, 
Dingwall Road, to St. James’s Road. An excellent section of 
this upper terrace gravel is shown in the Fairfield, near the 
East Croydon railway-station. On the north side, nearly parallel 
with George Street, the following beds are shown :— 
Cultivated earth passing into a yellowish sandy loam filled 
with Tertiary flint-pebbles and a few unworn flints, 3 to 4 ft. 
Brownish or yellowish-brown loam or clay with a few pebbles 
and unworn flints, 3 to 5 ft. 
Reddish flint gravel, for the most part without stratification, 
but in one or two places with thin beds of smaller pebbles, and 
lenticular layers of brown loam, 10 to 12 ft. The flints range 
from unworn to well-rounded nodules, and Tertiary pebbles. 
The only foreign materials noticed were pieces of iron sandstone. 
The gravel rests on Lower Tertiary beds. 
About three-quarters of a mile more to the north, in the 
Gloucester Road, at 178 ft. above O.D., a section now being 
worked showed above 2 to 3 ft. of brown clay or loam containing 
a few pebbles, and beneath this 12 ft. of reddish gravel of the 
same character as that in the Fairfield, but with a larger 
proportion of Tertiary flint-pebbles. 
Further northwards, near the Thornton Heath railway-station, 
at 145 ft. level, gravels have been worked over a large area to 
the north of the Brigstock Road. The section showed the 
following beds :—Cultivated earth and brownish loam with a few 
small pebbles, 2 ft. Reddish non-stratified flint-gravel, like that 
in the Fairfield, 7 to 10 ft. 
The gravel rests on London Clay. From the gravel at this 
place the late Mr. John Flower* stated that he obtained a 
molar tooth and some pieces of bone of elephant. 
Similar gravels to those above mentioned also occur at inter- 
mediate levels between the upper terrace and the bottom of the 
valley, and they may be traced from South Croydon through 
High Street, North End, London Road, to Broadgreen, at levels 
of 150-160 ft. above O.D., and beyond this they connect with 
the gravels of Thornton Heath. I have not been able to ascertain
