THE BURE AND ITS TRIBUTARIES.

In this region, moreover, no abnormal salinity (such as 
occurs in Hickling and Barton Broads) is found. Thus on 
October 31st, 1906, the following salinities were observed : — 
Grains per gallon 
Sutton Channel, opposite Laboratory . . 3.9 
Junction of Sutton and Stalham Channels . 3.8 
Stalham Channel, 20 yards above junction 
with River Ant ..... 3.9

When the figures for the salinity at various points of the 
river are examined and compared (see Tables X., XI., XII.)

It is noticed (1) that above Barton Broad the value was almost 
constant (3—4 grains per gallon). 
(2) That, as the Broad is crossed in a down-stream direc- 
tion, a rise to 6 — 7 grains occurs. 
(3) That, below Barton Broad, and down to Ant Mouth, 
it is about 7 — 8 grains. 
From this it is obvious that Barton Broad is supplying 
a small, but quite noticeable, quantity of salt to the water
