and “Atriplex" with here and there an isolated specimen of the “Yucca brevifolia” or Cactus palm, appearing principally in the “washes” which will be described further on.

As a general rule the vegetation, scanty at best, is always more plentiful and of a higher order in these depressions of the soil than in the higher and general plane of the surrounding country.  

In the lowlands, in the immediate vicinity of the river and its own progeny, or more properly speaking, its own product, the water spreading through the temporarily accumulated soil keeps it moist and more favorable to vegetation which springs from it in luxuriant wildness.

The first species to appear are generally the “Bouteloua sesleria” or mesquit[e] grass, with the pecular grass or fiber yclept “Tanglefoot” and the “Gallete” or rough bunch-grass, the least nutritious of the trio.  
As this stage the “Juniperus”, properly belonging to the flora of Arizona begins to enliven the scene.

Thick groves or plantations, if not a misnomer, of the different species of the arrowweed, the "Salix longifolia" "Tessaria borealis", "Baccharis coerulescens", and "Baccharis salicina", start out as if sown like wheatfields, the sombre and dusty tints of their leaves trenching in bold relief upon the brighter green of the other shrubs. 
Interspersed here and there among them we find the two species of the Mesquite tree, the "Algarobia glandulosa" and the "Strombocarpa pubescens", and finally along the margin of "lagunas" the most substantial of the Colorado timber, the willow and Cottonwood. 
The largest of these last, in the entire course of the river, are on what is called "Cottonwood Island" between Camp Mohave and the Grand Cañon where they have attained a size which may be styled majestic when the nature of the surrounding country is taken into consideration and this is due to the per-
