They deal respectively with the portions of the river 
lying 
(1) Above the Junction with Stalham Channel (Table IX.). 
(2) From this junction down to, and including, Barton 
Broad (Table X.). 
(3) Below Barton Broad, down to Ant Mouth. 
All these are seen to contain normal fresh waters, with a 
strong general resemblance to those found in the upper reaches 
of the Bure. The Permanent Hardness is somewhat lower 
that is usually found in the latter river. An average figure 
for the Ant is 3 — 4 degrees, but in the Bure 8 — 10 degrees 
are frequently found. (See Minutes of Evidence, House of 
Commons, 20th July, 1906, pp. 120-123.) 
From various isolated analyses it would appear that the 
water of the Stalham Channel, Sutton Channel, and Sutton 
Broad is similar to that of the River Ant. 
For example, in Sutton Broad, the following values were 
found : — 
Temporary Hardness 13.0 (28. III. 06)* 9.3 Sept., 1906. 
Permanent Hardness 5.0 (5. III. 06)* 3.4 ,, 
Salinity . . 4.5 (22. II. 06)* 3.4 „ 
* Analyses by Mr. H. Peel.
