as it almost always does. It ni\xes things inextricably, so '.hat in many 

 regions problems of geographic distributio!i will r.^main forever un- 

 solved. For illustration, consider clic Panaira Canal. If a careful bio- 

 logical survey of the w^aters of the two coas'.s and of tlie fresh waters 

 of the isthmus is not made before the canal is completed and water runs 

 through, many important problems wliich ought to bo solved will forever 

 remain unsolved. 



Mr. Titcomb : It is true that we get our rainbows from two or three 

 sources in California, and our steellieads from California, Oregon, 

 Washington and the Puget Sound region. Of course they have become 

 more or less mixed. Some have gone to Colorado waters, where eggs 

 have since been taken and shipped east. The stock at the Wytheville 

 station was obtained from different sources, but a part of it came from' 

 Colorado. 



\Vhile we are on the subject of acclimatized species, I want to an- 

 nounce tliat anglers are having great sport at Sunapee Lake, New Hamp- 

 shire, with the chinook salmon whicli has been introduced there from 

 the Pacific coast along with the silver salmon. This year I received a 

 letter from Mr. W. M. Kiel, of the Tuxedo hatchery in New York, 

 saying that many chinook salmon weighing from four to five pounds and 

 up to eight pounds are being caught. It is rather difficult to get hold of 

 specimens because people catch and eat them without letting us know 

 about it until afterwards. We are anxious to learn whether this Pacific 

 coast fish will adapt itself to our New England lakes and breed there. 

 Certainly it is furnishing great sport, and the New Hampshire Fish 

 Commission is very enthusiastic over it. 



Pre.sioent : What species did you say? 



Mr. Titcomb: Both the silver and the chinook salmon, but only the 

 chinook has so far been taken and officially identified. I think the silver 

 salmon may also be found, as we planted more silvers than chinooks. 



President : Do you recall the experiments of the Trocadero Aquarium 

 in Paris ? 



Mr. Titcomb : Yes. Chinook salmon actually breed there. 



President : I saw them. 



Mr. Titcomb : Yes ; and I saw their progeny. 



Mr. Meehan : Mr. Titcomb's reference to the silver and chinook sal- 

 mon reminds me of our experiment with silver salmon. Two years ago 

 we received 100,000 eggs from the Bureau of Fisheries and sent them to 

 the Wayne hatchery. I retained 10,000 fry and endeavored to rear them. 

 The rest have been planted in certain streams in Wayne County tributary 

 to the Lackawaxen and Delaware Rivers. Several small specimens of 

 silver salmon were caught by fly fishing before the close of the season. 

 The fish were four or five inches long and were brought to the hatchery 

 for identification. Meanwhile the 10,000 that we retained grew rapidly, 

 took food and remained perfectly healthy. Tliey are now about a year 

 dud a half old and will run from six to nine inches in length. They rise 

 very freely to the flies that skim the water and take food eagerly and 

 show every sign of being a fish that will thrive in confinement in fresh
