254 MR. A - G - INNES on tidal action in 
portion going further up the Bure, the other up the Thurne 
River. 
The latter action at the Thurne-Bure junction was studied 
by Mr. Lincolne Sutton in connection with the Yarmouth 
Waterworks Case. (See Minutes of Evidence before the House 
of Commons, 20th July, 1906, pp. 105, 126, 127.) 
In the Thurne River it was found that as the tide ebbed 
the salinity of the river rose at one place from 12 to 32 grains 
per gallon, thus proving that the ebb down the Thurne River 
raises the salinity. The converse may fairly be inferred. 
The waters of the Thurne River are thus salt at their source, 
and are diluted on their passage down the river, partly by 
Bure water pushed up by the rising tide.
