CHAPTER V. 



RIVERS, RAPIDS, CASCADES, ETC. 



1. You would not ride far on a railroad 

 without crossing one, perhaps several, rivers, 

 which are streams of water always flowing 

 toward lower ground. Do you know how they 

 are formed, where they come from, where they 

 go, and what good they do ? 



2. Look at the chart and you will see 

 several rivers. Some are formed by rain which 

 sinks into the ground and appears again at 

 openings in lower ground as springs, and others 

 are formed far up the sides of mountains merely 

 by the melting of snow.
