 have great highways heneath the hills. Water 

 charged with carhonic acid gas has a very sharp 

 tooth and a powerful digestion, and no limestone 

 rock can long resist it. Sherman's soldiers tell of 

 a monster spring in ^Northern Alabama, — a river 

 leaping full-grown from the bosom of the earth; 

 and of another at the bottom of a large, deep pit 

 in the rocks, that continues its way under ground. 



There are many springs in Florida of this charac-

 holes, as it were, here and there. In some places 

 the water rises and fills the bottoms of deep bowl- 

 shaped depressions; in other localities it is reached

 down by a rope, and if it becomes detached is 

 quickly swept away by the current. Some of the 

 Florida springs are perhaps the largest in the world, 

 affording room and depth enough for steamboats to 

 move and turn in them. Green Cove Spring is 

 said to be like a waterfall reversed; a cataract rush-

The Valley of the Shenandoah is remarkable for
