The formation of natural bridges. 



Am. Jour. Sci., 4th ser., vol. 20, pp. 119-124, 3 figs. 



Suggests the following theory to account for the origin of the natural 

 bridges at North Adams, Mass., Lexington, Va., Chattanooga, Tenn., in 

 Utah, and in the Yellowstone National Park: "Before the formation 

 of the bridge the stream which now flows under then flowed upon the 

 surface of what is now the arch and probably plunged over a fall a 

 short distance below the present site of the bridge. A portion of the 

 water percolating through a joint plane or crack upstream discharged 

 into a stream under the fall and gradually enlarged its passage of its 

 solvent power. In the course of time this passage became sufficiently 

 large to contain all of the water of the s-tream, and the bridge resulted."
