436 Report of Experimental Committee. 



The other marked fish recaptured include a Grilse marked on 

 25th October, 1873, when ascending the river to spawn, and was 

 recaptured on 1st April, 1874. When returning as a Kelt to the 

 sea, it had, of course, decreased in weight. 



The 12 Black Tails recaptured had apparently never left the 

 river after being marked, and with four exceptions had decreased 

 in weight. 



The Committee having excavated a pond at Carham 42 feet in 

 length, 19 feet broad, and 3£ feet deep on the side of Carham 

 Burn, from which it is supplied with water, had two meetings 

 there — the first upon 7th May, 1874, when 133 Orange Fins were 

 caught in the river Tweed and placed in the pond ; and again on 

 8th July following, when 76 of the fish in the pond were taken 

 with a net, and after examination returned to the pond alive. 

 They were, with a few exceptions, in a plump, healthy condition, 

 but had not assumed the Black Tail markings. 



Bullock's liver has been supplied to them for food at the rate of 

 3 lbs. per week, increased to 6 lbs. per week after the 8th July ; 

 the fish have also a good supply of insects from the burn. 



Another small pond or tank has been made at Carham, and 

 supplied with water from a spring. In this pond Mr Huntley's 

 fisherman (Thomas Sligh) placed a number of Orange Fins, one 

 of which has assumed the Black Tail markings.
