The water tanks should be of wood, lined with pure tin or 

 with slates. ' The water from the iron tanks was filled with 

 rust in a week, and, although filtered, is very likely to have 

 held in minute suspension a considerable quantity of sediment. 

 I strongly suspect that the slime so much complained of by 

 Mr. Black in the former experiment was nothing but this 

 deposit of rust, and not due to the presence of confervse as 

 supposed by him. 



The water in the wooden tank lined with tin on board the 

 "Beautiful Star" is as bright and well-tasted as on the day on 

 which it was put on board. 



Taking into consideration the pertinacity with which a 

 portion of the Ova retained life for 74 days, in spite of the dis- 

 astrous circumstances to which they were subjected on the 

 recent voyage, I cannot doubt that salmon can and will be 

 introduced into this colony. But to effect this no pains should 

 be spared to obtain the services ot a large clipper ship, and if 

 the funds now remaining in the hands of the Commissioners 

 are insufficient an appeal should be made to the Government 

 of this and the neighboring colonies to supplement them. The 

 Governments of Victoria and New Zealand have already 

 borne a share in the undertaking, but the older colony of 

 New South Wales has determined on trying the experiment 

 for herself. I think it is to be regretted that the resources 

 which might be made available for certain success should be 

 thus divided, as success in this colony would at once ensure it 

 in all others whose rivers are adapted for salmon.
