our Atlantic streams possess was offered it, but none of them 

 were favorable and the fish was unable to accommodate itself 

 to any of the rivers. 



Mr. Mather. — The aquatic fauna of our Western coast 

 more clearly resembles that of the west coast of Europe than 

 that of our Eastern coast, and this fact may be a bar to the 

 acclimatization of some species of fish, here or in Europe 

 Our Eastern charr, which we call the brook-trout, does not 

 thrive in England, while the rainbow trout does. The latter 

 fish lived with us, in the East, but its eggs do not impreg- 

 nate well, and I do not believe that it would perpetuate itself 

 in our streams if left to itself. Attempts have been made to 

 introduce the sole from Europe, but I doubt if the rocky 

 coast of Massachusetts will ever prove a home for them. In 

 my opinion this fish will never thrive north of New Jersey, 

 and if I were asked where to plant them I should say South 

 Carolina, and I would not insure their success there, because 

 of this difference between the Eastern and Western shore of 

 the Atlantic. 



Dr. Bean. — Our brook trout, when introduced into English 

 Waters, seems inclined to migrate, much as the rainbow trout 

 does with us. There is a movement among the trout before 

 the spawning season, usually in September. With us the 

 fontiiialis starts up stream for the spawning beds, but in 

 England the movement seems to be down stream. Just what 

 this different habit of this fish means we do not know, but 

 there seems to be a great difference in the habit oi fontinalis 

 when transplanted from Eastern America to Western Europe, 

 as there are in other fishes which Mr. Mather has cited. The 

 European carp, when transplanted to America, has thrived, 

 and, in places, exceeded its rate of growth in Germany. 



Mr. May. — In our new country, where almost every stream 

 has a saw-miil on it, the effect of sawdust is a question for 

 the fish culturist to consider. On many streams the fish 

 have been destroyed, or driven away by sawdust. 



Dr. Kingsbury. — The evil effect of sawdust in our streams
