Notable year 
for Bourne 
flows. 
Description of 
Plates. 
44 
In conclusion I may say that the present year isa 
notable one for the appearance of Bourne flows, and 
wherever the chalk formation extends in the counties of 
Hants (including the Isle of Wight), Hertfordshire, 
Kent, Oxfordshire, Surrey, Sussex, and Wilts, Bournes 
have made their appearance in larger volume than 
usual. 
Plate No. 1 shows a general plan of the district in 
which the Croydon Bourne occurs, and also the Marlpit 
Lane Bourne, and a longitudinal section down the 
Caterham Valley to Croydon, and Plate No. 2, shows 
in a graphic form the relative volumes of the Bournes 
of 1877 and 1904.
