irideus). At Southampton, England, on February 23, I received 25,000 Atlantic 

 salmon (Salmo salar) eggs from the Earl of Denbigh's fisheries in North Wales. 

 On March 1 7 I arrived at Buenos Aires, but I was unavoidably delayed here for 

 10 days. The losses from the time the eggs were packed at the hatcheries in the 

 United States and North Wales until reshipped on March 27, en route to the 

 Santa Cruz hatchery, in southern Argentina, were as follows : Ouinnat and sockeye 

 salmon, i per cent each; brook and lake trout, the same; silver and landlocked 

 salmon, 2 per cent each; Atlantic salmon, only 5 per cent, while it was 20 per 

 cent on one lot of rainbow and 60 per cent on another. From this time until all 

 of the eggs were hatched, April 30, the losses of eggs and alevins were as follows: 

 Quinnat and silver salmon, only 2 per cent; sockeye salmon, 4 per cent; lake 

 trout and landlocked salmon, only 5 per cent; brook trout, 20 per cent (mostly 

 fish hatched en route because of the delay in Buenos Aires), and Atlantic salmon 

 and rainbow trout, about 50 per cent. 



The following table shows the number of each species on hand at the Santa 

 Cruz hatchery May i, 1906, and again on November i, 1906, with losses, plants
