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 angler in a day, but it 
is never caught except in one particular locality. It 
spawns in the lake on a fine gravel beach, in three feet of 
water, and does not enter the inlets. Nothing but smelts 
are ever found in its stomach. Flood’s Pond contains 
neither perch nor bass. 
Since, then, by reason of dams on the outlets, no fishes 
of marine ancestry could, within the last fifty years, have 
gained access either to Dan Hole or Flood’s Pond without 
artificial help—since land-locked salmon only have been 
planted in these ponds, and that quite recently—and since 
there seems to be trustworthy evidence of the existence of 
this so-called silvertrout in each body of water for at least 
half a century—it is fair to conclude that the Sulvelinus 
alpinus aureolus is a native of two Maine drainage basins, 
and therefore is aboriginal to New England, an American 
representative of the European saibling, red charr, or 
ombre chevalier. 
But this does not prove its aboriginality to Sunapee 
Lake, N. H., although, all circumstances considered, it 
renders such aboriginality highly probable, inasmuch as 
no data exist to establish a plant of this variety at any 
time in Sunapee Lake, and no German saibling eggs were 
brought to New Hampshire before January, 1881. The 
fact that the fry from the eggs sent to Plymouth in that 
year were placed in Newfound Lake, a body of water ap- 
parently in every way adapted to the. nature of the saib- 
ling, but have never been heard from, is further significant 
here. It may prove that the foreign fish cannot find the 
necessary conditions in the New Hampshire lakes. The 
failure of the farmers at Sunapee to distinguish between 
the large brook trout and the saibling (if the latter fish 
was a native) is in contrast with the positive knowledge of 
a difference at Dan Hole and Flood’s Ponds. Its explana-
