“My Lorp, 
“ Mr. James Burnett, Chief Clerk in the Survey Depart- 
ment, when on leave in England visited Mr. Young, the manager 
of the Duke of Sutherland’s Salmon Fisheries, for the purpose of 
consulting him as to the practicability of introducing the Salmon 
into the rivers of this Colony. 
“Several attempts have been made to bring out the spawn, 
but they have all failed: as, however, Mr. Young is a practical 
man, who is probably better acquainted with the habits of the 
fish than any person to whom application could be made,—as 
he is willing to supply the fish,—to superintend all the necessary 
arrangements which may be made for their safe conveyance to this 
Colony,—it would, I submit, be very desirable to make the experi- 
ment, which can cost but little, and the result of which, if successful, 
may prove of great benefit to the Colony. 
“« The simple plan would be, to allow the tanks, or whatever may 
be necessary to contain the fish, to be placed upon the poop of one 
of the Convict Ships coming out to the Colony, with directions to the 
surgeon to take charge of the fish, and comply with the directions 
given by Mr. Young. A trifling premium may be held out, should 
the fish arrive in safety, as an inducement to the surgeon to take 
some trouble in the matter.
