We cannot well overestimate the importance of this discovery; for the rapidity with which the water level has lowered over wide areas starts very serious questions as to the many future needs of a constantly increasing population. There is still another relation existing between our forests and water in which we can readily notice the danger of water on cleared ground. To put the prob- lem in concrete form, study the condition along the mam hne of the Peimsylvania Railroad near, say Tuscarora Station. On the one side you have Juniata River, on tiie oiher liie slope which lias descended a thousand or more feet from a timber-covered, rocky mountain. We will suppose that one of the torrential summer rains has occurred a few hours before. On the river side you will see a muddy, more or less swollen stream. The nuuldy color is due to the wash from the f(>rtile farm lands through which the river has come It represents the best, most soluble jiart of the soil. Its loss is in ev(>ry instanc(> a detriment to the farm from which it has come. On the mountain side of the road- bed you Will see many small streams tumbling down over a rocky bed; but, if you observe closely, you will hnd that the water is usually almost clear, sometimes It IS wholly clear, and it is almost never muddy though, owing to the steeper slo)^ down which that water has come, the tendency to washing out of soil was jrreater than on the river side. The reason is plain : on the forest flooi- (he bed of leaves arrested the rapid flow of water, covered and protected the soil.
