 the young fish were distributed as follows:

March 30th, 1878— Santa Rosa and Mark West Creeks 3,000 



April 5th, 1878— Santa Cruz, Aptos Creeks, etc 4,000 



April 8th, 1878— Alameda Creek and tributaries 2,500 



April 7th, 1878— Streams in Santa Clara County 2,000 



April 18th, 1878— Streams in Santa Cruz County 10,000 



May 9th, 1878— San Lorenzo Creek, Alameda County 1,000 



May 9th, 1878— Streams in Alameda County 5,000

The few Dolly Varden trout that we succeeded in hatching were 

 distributed in streams at the summit, and in the Truckee River. 



In September we purchased 50,000 young Tahoe trout that had 

 been hatched by Mr. Frazer, and distributed them in the Truckee 

 River, in the North Fork of the American, and in the South Yuba. 

 These fish were placed in the Truckee on the petition of the people 

 residing on that river, who complained that for some years the trout in 

 that stream had been gradually decreasing in numbers. There are 

 now fish ladders over the dams on the Truckee, and, if maintained, 

 it is probable a supply of trout can be kept up in this river. 



The eastern trout does not appear to thrive in the streams of the 

 Coast Range of mountains. These mountains are composed of sand 

 stone, which is readily worn by the winter rains and, at certain sea- 

 sons, all the streams from them carry a large amount of sediment 

 and become more or less discolored. There is also a great diff'erence 

 in the temperature of the water in winter and summer. The native 

 home of the eastern trout, as its name implies, is in the clear cold 

 sources of mountain streams. Wherever planted in the cold clear 

 streams of the Sierra Nevada, in water flowing over granite and slate, 

 they find congenial homes, and thrive and propagate equally with 

 the native trout. 



Probably there is no trout more valuable for wide distribution 

 than the Pacific Coast brook trout {Iridea). It grows rapidly, occa- 

 sionally weighing seven pounds when it can feed in salt water at the 

 mouths of coast streams, and often weighing five pounds when con- 

 fined entirely to fresh water containing an abundance of food, as in 

 the McCloud River. Some specimens of McCloud trout, kept m the 

 hatching-trough in the fishery at San Leandro, grew to average 

 seven inches in length in one year from the time the eggs were 

 placed in the hatching trays. It does not seem to be injuriously 

 affected by a long continuance in water containing a large amount 

 of muddy sediment. We are not aware of experiments having been 

 made to test, with exactness, the highest temperature of water m 

 which it will exist and thrive, but without doubt it will live in water 

 so warm as to be fatal to eastern trout. We believe it could be suc- 

 cessfully introduced into streams on the Atlantic Coast where eastern 

 trout would not thrive.
