636 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



salmon aud placed in the vessel along with them. In a few days it had 

 all disappeared, and produced no effect. Another method was sug- 

 gested by Mr. G. H. List, who also kindly furnished me with material 

 for the trial. Pieces of skin with this fungus growing upon them were 

 cut from the bodies of dead salmon at the river side, and were put into 

 wide-mouthed bottles, which were at once fiUed with river water, the 

 skin not being allowed to dry. On receipt of the bottles the pieces of 

 skin, along with the water in which they were brought, were emptied 

 into the vessel among the minnows. The water in the vessel was not 

 changed for three days, at the end of which time the minnows were still 

 unaffected. Fresh water was then put in the vessel, and the pieces of 

 skin retained in the water, which was changed every second day for 

 eight days. The minnows were not disturbed by the pieces of skin. 

 They nestled under them and nibbled every morsel of fungus from them, 

 hiding and playing about them until they had to be removed from pu- 

 tridity. All the minnows are still alive and are in beautiful condition, 

 taking food greedily, worms cut small and crystals of sugar being their 

 favorites. They have been kept since 14th May till now (12th July) 

 and are as healthy and lively as when put in the vessel.
