 sides of rivers become more and more bare, until they reach 

 the Columbia, where, for a short distance, vegetation once 

 more assumes its usual vigour, soon to leave the banks un- 

 clothed again, except some low shrubs, for a distance of about

 formation into almost every recess ; amongst them is the Phi- 

 ladelphus, at first very seldom met with, but becoming more 

 plentiful, and at last very abundant, downwards. Near the 

 junction of Clark and Columbia rivers, it grows mixed with
