(1911)
The excavation of valleys by waterfalls is one of the best known and most effective processes by which rivers cut down the surface of the earth. The influence of waterfalls is usually regarded as solely destructive, and as always helping to lower the land. They undermine and cut backward the rock faces over which they fall : by this recession they excavate deep gorges ; and the existence of these gorges enables the adjacent country to be lowered to the level of the valIey floors. The waterfalls, moreover, empty any lakes they rnay reach in their retreat, while the ravines below the falls may drain the springs and thus desiccate the neighbouring hihlands. Observations in various countries had suggested to me that waterfalls may sometimes be constructive in stead of destructive, and that they may reserse their usual procedure, advancing instead of retreating, filling valleys instead of excavating them, and forrning alluvial plains and lakes instead of destroying them. The best illustrations I have seen of such advancing, constructive waterfalls are on some rivers of Dalmatia and Bosnia, where they occur in various stages of development. ...
