In but three of the fifteen mill dams above enumerated has any 

 attempt been made to comply with the provisions of the bye-law. The 

 fish -pass on the Dumfries cauld at present lacks one of the chief 

 requisites of success — viz., an attractive entrance in a proper position. 

 Further, the fall from one pool to another is greater than is desirable 

 in a properly constructed pass, while the pools are not of sufl&cient 

 depth. The fish-pass on the Cairn mill dam does not afford a free 

 passage to fish in terms of the bye-law, and falls short of its miiiinium 

 recjuii'ements in the following respects, viz. : — First, the upper sill of 

 the pass is level with the crest of the dyke instead of being not less 

 than six inches below its lowest part; second, the gradient of the pass 

 is steeper than five horizontal to one perpendicular; and third, the foot 

 or entrance to the pass projects beyond the toe of the dam. The down 

 stream face of the mill dam on the Euchan, instead of sloping at a 

 uniform gradient throughout, is made in four steps, and the fish- 

 pass is formed by dishing or hollowing out a pool in each step. But 

 owing to the pools being too shallow, and the steps too high, fish would 

 have great difficulty in ascending. Further, there is no cutting in the 

 crest of the dam where these pools are situated, and the gradient of 

 the fish-pass is steeper than the maximum permitted in the bye- 

 law. In the case of the other mill dams in the district na
