RUNNING WATERS 
book makers, but I never saw either of them 
that hue. They are usually a drab color, 
and sometimes after rain, yellowish or brown- 
ish. In local hue they are not attractive 
to look upon, but muddy water does not make 
a bad reflector of the sky. Indeed, the Rhine 
and the Seine are often beautiful in their re- 
flections and show us many odd, amalgamated 
colors. For clouded water will not reflect the 
same hues as clear water. Even the brown- 
hued water in the wood-lakes of America will 
darken the green of the overhanging leaves in 
reflection, and make the white flower of the 
dogwood appear of a grayish tone ; and a muddy, 
yellow-hued river like the Tiber will sometimes 
cast pinkish reflections and occasionally toss 
up little crests that appear cream-white. The 
Thames, too, takes on an infinite variety of col- 
ors under different lights ; and in cloudy weather 
the Arno is just as fitful, just as changeable. 
There is a third stage in the river’s course 
remaining to be traced—the Mountain Track. 
It is usually called the first stage, but for the 
sake of convenience we are following up from 
the sea and reversing the order. In its Valley 
and Plain Tracks the river remains a river, 
but in its mountain course it is usually little
