 Between the mouth of the canyon and the channel of the 

 river one finds the usual fringe of willow, alder "and cottonwood, 

 and in the swampy places are found the typical water plants of 

 the region. At the present rate of change and improvement, 

 and owing to the frequent fires that sweep the vegetation clean 

 from the upper sections of the arroyo, the botanist wilTsoou'look 

 in vain for many of the plants cited in the above lists, and at 

 any rate this study may serve as a record for comparison with 

 the flora of the future.
