268 The American GeoUxjiHt. April, 1897 
ed by a second discussion in Nature* during the years 1873 
and 1874, and numerous lakes with more thnn one outlet were 
cited from many parts of the world. Norway, the British Isles, 
Africa, Central America, the United States and Canada, were 
the countries from which this lake principle was illustrated. 
Since the first example was made known others have been dis- 
covered and published upon, from time to time, principally, 
of course, by exploration parties. 
Many of the instances cited in the early and middle litera- 
ture were by tourists, or for the most part, by untrained nat- 
uralists. If lakes were seen with more than one overflow they 
did not impress themselves upon the observer as being out of 
the ordinary — and in several cases were described from pure 
memory, after a long time had elapsed since the visit, wliich 
proved each time to be erroneous. 
Several lakes illustrative of this condition, proved at the 
time to have two overflows, but after careful examination one 
of the overflows was shown to be artittcial, serving the pur- 
pose of supplying water power for running machinery, etc. 
Colonel George Greenwood visited many of the localities from 
which thiscondition had been described, and succeeded in sat- 
isfactorily setting aside the statement, that these lakes were 
draining through two naturnl outlets. Thesu with other care- 
ful after-examinations of the lakes first described has greatly 
diminished the number ; however, there still remain a few 
which have not been disproven but stand as authentic, and 
everv one, so far, is located in an area that has been more or 
less recently glaciated. 
During the past summer while a member of the Cornell 
Greenland party in company with the sixth Peary Arctic ex- 
pedition, the writer observed and noted several lakes having 
more than one outlet. These were scattered over the surface 
of an island located in Hudson strait, directly off the south- 
ern coast of Baffin land, named Big island. Two lakes of 
this kind were given special attention. 
The first lake was a true rock basin, as one could walk en- 
tirely around it on the rock in .place, save a short distance
