the picture the arrangement of dark and light is rhythmical. I have only touched upon the broad general plan of contrasted darks and lights, and must leave you to study for yourselves the intricate and subtle effects with which the picture abounds; for example, the fine threads and little dots of light and dark that form a tangle on the left bank; or, on the right, the mass of leafage in half shadow against which the trunk of the tree shows very dark. You know the old proverb about leading a horse to the water. I can draw your attention to these things, but I can not make you feel their beauty. I think, however, I can promise you, that, if you are sufficiently interested in what we are talking about to really study this picture, to explore carefully the lighter parts and peer into the shadows to see what lurks within them, its beauty will make itself known to you.
