A FOREST BOULDER 



A huge boulder showing nil stages in Nature's preparations for plant growth. The lower sides are now 

 covered with lichens alone, while the parts above are covered with leafy-mosses which made their start in lichen 

 debris. Ferns nestle in the mosses and a spruce tree sits astride the rock . . .
