NATURE FOR ITS OWN SAKE 
On dark 
wuters. 
On strong- 
hued waters. 
The point 
of view. 
a peat-water lake, like Loch Laggan in Scot- 
land, the white clouds show gray, the gray 
clouds look sooty or smoky, and the cerulean 
blue of the sky turns to deep ultramarine. On 
Loch Dhu, a dark little lake in the Grampians, 
surrounded by high hills covered with nothing 
but bluish stone and yellow-green grass, one 
can see in the wave reflections, the grass 
turned to dark orange and the stones to cobualt- 
blue. Dark local tones in the water will 
darken the colors in reflection, and light tones 
will lighten them. A muddy or yellow lake will 
not reflect a brilliant hue of any kind without 
bleaching it. As for waters neither light nor 
dark, but nevertheless positive in hue, they 
will often tinge the reflection with their own 
intensity. Thus the waters in the Venetian 
canals reflect the side of a black gondola, but 
the reflection is not black ; it is greenish—the 
local color of Venetian water. Again in de- 
termining hues, local or otherwise, much de- 
pends upon the angle from which lights, colors, 
and reflections are seen. From one point of 
view the lake may be all local color ; from an- 
other point of view it may be all sky reflection. 
So that when the disturbing elements taken to-
