mitted to you in mine of the 15th ultimo differs from the plan sub- 
mitted by the Lieutenant-Governor of the Colony, whose proposal, 
as you will perceive, is confined to forwarding the fish in tanks, 
to be placed on the poop of Convict Ships going out from this 
country. With respect to the employment of a Smack for the con- 
veyance of the Salmon, I am to acquaint you that the expense would 
be far more than that which the Government would be able to incur 
for the object in question; I am therefore to request that you will 
inform Lord Grey how far it would, in your opinion, be practicable 
to send them out in the manner proposed by Sir W. Denison. ;

“ Sir, 
“‘ T have received yours of the [8th instant, and in reply beg 
to state that my opinion is, that it will be practicable to carry old 
Salmon alive to Van Diemen’s Land in tanks fitted up on the poop 
of a Convict Ship, as suggested by Sir W. Denison, but not so prac- 
ticable with Smolts (young Salmon),—and from the distance, at all 
events the length of time on the way, and the climate, the ova cannot 
be depended on. 
“ Ist, The old Salmon are capable of enduring more fatigue and 
hardships than the young ones are; and when they are put into a 
river in Van Diemen’s Land, they are certain to remain in that river 
until their spawning process is over. 
“© 2nd. When the ova (eggs) are hatehcd in any river, the Smolts 
produced therefrom, when they go from that river to the sea, are in 
course of time certain to return to the same river where they were 
hatched. Whereas Smolts carried from this country and put into 
these strange rivers, after going down to the sea, might not return 
to the river with the same punctuality as they-always do to the rivers 
in which they are bred; therefore the old fish are preferable to the 
young in this case. : 
I enclose a copy of the letter I got from Mr. Burnett on the sub- 
ject; and, although I can have no doubt that the fish can be carried 
out in tanks as proposed, I must say that if Government would
