Have you ever been in the country, or in a city park, after the green of
the maple-trees has turned to scarlet and gold? If you have noticed the
trees in their gorgeous hues, you have probably found that the grass,
also, shows patches of color not seen in the summer-time. The sky is
often very blue, and its color is reflected in the quiet water of a lake
or pool, or in a gently flowing stream.
