144 TRANSATIONS OF THE [MaE. 13 



fields and glaciers, they swarmed into many lake-basins, where 

 they became extinct before the advent of the white man. Were 

 l^erch the instruments of extermination ? If so, why did they 

 not put in as thorough work at Sunapee ? 



It is but right to state at this point that the history of the 

 charr in some Eurojjean lakes is the history of a fish that has 

 disappeared within the memory of man. This is notably the 

 case at Loch Leven, once the home of a charr that rivalled the 

 magnificent fish of Windermere. The trout {fario) seems the 

 fitter to survive. 



While the discussion just outlined was progressing, charr 

 identical with the Sunapee Lake form were sent from Dan Hole 

 Pond, Carroll County, New Hampshire, and from Flood's Pond 

 in the town of Otis, sixteen miles from Ellsworth, Maine, to 

 Professor Garman and Dr. Bean. The water of both these lakes 

 is deep, clear and cold, as in the case of Sunapee. Dan Hole 

 Pond, at the head waters of the Ossipee River, is tributary to 

 the Saco. Flood's Pond connects with the Union Kiver, which 

 enters Blue Hill Bay near Mt. Desert. Thus the new Salvelinus 

 is represented in three distinct drainage basins in New 

 England. 



In compan}' with Colonel Hodge I visited Dan Hole Pond in 

 the summer of 1889, but failed to secure a specimen of the 

 saibling. In the fall of 1890, however, several specimens were 

 sent from the pond to Cambridge and to Washington, where 

 they were pronounced identical with the Sunapee form. Old 

 residents declared them identical, also, with trout which had 

 for fifty years been speared on the same spawning bed. The 

 present representative from Ossipee informs me, through Com- 

 missioner Hodge, that he has seen many individuals of this 

 species weighing 10 and 12 pounds — -all this, years, before a 

 German saibling egg was imported. 



I am indebted to Dr. Walter M. Haines, of Ellsworth, Maine, 

 for the following facts regarding Flood's Pond: The Pond is 

 three miles long by three-fourths of a mile wide. It is sur- 

 rounded by high, well wooded land, and is one hundred feet 

 deep, the bottom being pure white sand or gravel. There are the 

 usual inlets and spring-holes. The outlet is a stream of con- 

 siderable size, and has been dammed in many places for the last 

 forty years. The Flood's Pond saibling, declared b}' Professor 

 Garman to correspond exactly with the Sunapee fish, is known 

 in the neighborhood as the "silver" or "white trout," to 

 distinguish it from "the square-tail" or brook trout, and 

 "the togue " or lake trout. It attains a weight of five or six 

 pounds. Two hundred pounds have been taken by a single
