144 TRANSATIONS OF THE [Mar. 13 
fields and glaciers, they swarmed into many lake-basins, where 
they became extinct before the advent of the white man. Were 
perch 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 European 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, asin 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 River, which 
enters Blue Hill Bay near Mt. Desert. Thus the new Salvelinus 
is represented in three distinct drainage basins in New 
England. 
In company 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 by 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
