therefore, yield fair rainbow trout fishing, though not, and probably never will, equal 

 the yield that other kinds do. 



"Newville spring, above referred to, is the natural home of the brook trout, but it 

 has been plentifully stocked with California or rainbow trout, and it is one of the very 

 few streams in Pennsylvania in which that species of fish has been known to propagate 

 naturally. Newville spring has considerable depth and width." 



Eggs were shipped from California to Japan and were received by Sekizawa 

 Akekio on June 9, 1877. In 1880, when nearly three years old and sexually mature, 

 the trout averaged nineteen inches in length. 



Doctor Leon Lefort, Vice-President of the Society of Acclimatization, of Paris, 

 reared rainbow trout in a pond of a hectare and a half in Sologne. The young trout, 

 furnished by the Trocadero Aquarium, were about eight centimetres (three and one-fifth 

 inches) long when they were placed in a pond of moderately high temperature. There 

 was no mortality, and after two years they reached an average length of two feet. 



In the aquarium at The Hague, Holland, in 1894, rainbow trout and American 

 brook trout were among the live fish on exhibition. The aquarium at the Antwerp 

 Exposition in the same year contained numerous specimens of the rainbow. In the 

 Trocadero Aquarium, Paris, where the eggs of the rainbow were first hatched in 

 Europe, both the quinnat salmon and the rainbow were represented by many fine 

 examples, and the rate of growth appeared to be more rapid than in their native waters. 



In Mexico the rainbow has been successfully introduced and is now acclimatized.
