benefit resulting from his labours. 
In Canada and Nova Scotia establishments for the 
re-stocking of the waters by the artificial incubation of 
fish have been in operation for some time. 
In a letter just received from Sir Robert Officer, Chair- 
man of the Tasmanian Salmon Commissioners, very en- 
couraging accounts are given of the success of the 
salmonidce introduced into that colony. He says : — “ I 
have just had the pleasure of receiving your note, in which 
you ask for a further supply of ova, and in reply I beg to 
assure you that everything in our power will be done to 
meet your wishes. We have this season the prospect of a 
very large produce of ova and young fish, both in the 
ponds, and in the Plenty River adjoining, as well as in the 
other tributaries of the Derwent. The rills connected with 
the ponds, and the bed of the Plenty for several miles of 
its course, may be seen thickly studded with the redds of 
the fish, in which will be found, I doubt not, the whole 
three species of salmonidce in vast numbers. The Plenty 
is but one of the many fine streams connected with the 
Derwent, in which it is scarcely to be questioned that the 
same promising state of things at this moment exists. The 
spectacle is one that would delight you to behold.” 
In Scotland, that of Stormontfield on the Tay, and one 
at Oughterard in Galway, have produced valuable results. 
Norway and Sweden have their fish-hatching establish- 
ments ; Russia and Denmark have theirs at Nikolskoi and 
Yiborg. Germany has now obtained Huningue, and 
Austria has a piscicultural establishment at Salzbourg. 
Italy has for ages cultivated her lagoons at Comacchio. 
While all these nations have learned the value and profit to 
be realised from the cultivation of their waters and seas, 
shall Australia remain inactive ? The same enterprise
