Painting Rocks With Mush.

In the zoological gardens in London they have just finished building a series of concrete hills and terraces upon which wild, animals will rpam at large under conditions as nearly natural as possible. These hills and terraces have been painted with a mixture of oatmeal mush and Sonemeal, the object being to add phosphate to the lime Of the concrete, phosphates being essential to the growth of moss and lichens. It is believed that this coating will capture the spores of mosses and lichens and enable them to grow, thus making the surface of the rocks green and more natural in appearance than the bare concrete.
