The waters of the great inland lake fell per- 

 haps a hundred feet and then they made a pause. 

 The exposed shores dried out. They baked hard 

 in the sun, and were slowly ground down to sand 

 and powdered silt by the action of the winds. 

 The waters made a long pause. They were re- 

 ceiving reinforcements from some source. Pos-

 now, and the streams entering the lake from 

 the mountains were much larger. Again there 

 may have been underground springs. There 

 are flowing wells to-day in this old sea-bed

 self. No one knows their fountain-head. Per- 

 haps by underground channels the water creeps

 high water had made a breach of some kind in 

 the dam of its own construction and had poured 

 overflow water into the lake by way of a dry
