Life History of the Trout. 



The only members of the family Salmon idae that have 

 been acclimatised in South African waters are the Brown, 

 Rainbow, and Loch Leven varieties. The first attempt 

 was made by a Syndicate in the Eastern Province of 

 Cape Colony, to which the author was a subscriber, in 

 1881. To Mr. .J. D. Ellis of Kingwilliamstown must be 

 credited the inception of the idea, and the first shipment 

 of ova arrived in 1885, but the experiment was a failure.
