The uncultivated bank growing weeds or grass is a seriousobjection to this form, as it is a breeding place for injurious insectsand a home for moles, mice and other animals. Very often thewater from the slope above finds its way into one of their burrowsand a considerable gully forms in a short time. A terraced parkis shown in figure 179.

While the natural slope was stable under theprotection of the ^drgin forest, it was necessary to terrace to prevent devastating erosionwhen the land was cleared. (Bureau of Soils, U. S. D.
