The trees, the bushes, the field grasses were 
already tinged with autumn hues, and these 
hues, enhanced by the heat, made the land- 
scape appear crude and violent in its coloring. 
No imaginable tint was absent from the scene, 
and the greens, reds, yellows, and oranges were 
flaring in their intensities. But what impressed 
me more than anything else was the iridescent 
coloring of the atmosphere, the wavering of 
the heated air, the faintness of the shadows 
and their pronounced body of color. The pre- 
vailing tints in the shadows were lilac, violet, 
and rose. There were few shadows that were 
colorless, and few, if any, wherein the local 
color of the ground or object they fell upon was 
not twisted or distorted somewhat by a reflected 
or a complementary color. 
It is not a new theory of science that every 
color casts its complementary hue in shadow. 
The practical working of it may be frequently 
observed in nature. A sheet of white paper 
catching the light from a red sunset will receive 
a green shadow from an object interposed be- 
tween the paper and the sun. The same red 
light of sunset falling upon snow will some- 
times produce green in the shadows of trees
