 storm cloud is passing over, only to awake to active flight al- 

 most the instant that the sun comes out again. 



The dirty, smoky city covers a great deal of ground and it 

 is something of a walk from the " up town " hotels into the 

 wooded hills which rise on every hand. The large timber, if 

 there ever was much of it, is now mostly gone and the re- 

 maining trees are chiefly so dwarfed or undersized as to be of 

 no use for commercial purposes. To this they owe their ex- 

 istence and as they still support some insects let us hope that 

 they may long remain undisturbed. Many of the large ra- 

 vines and gulches have been ruined entomologically by exten- 

 sive mining operations but a few spots were- found which 

 yielded tolerably well. The stony porous soil of most of the 

 hillsides holds but very little water and supports a fauna, 

 which is in strong contrast to that of the marshy valley region.

 valley from Buena Vista, where it was seen rather abun-

 near enough to Leadville to make the summit, though far 

 above timber line, tolerably easy of access on foot, we took

 with a good deal of bodily discomfort, owing to the rains and

 up. 



Following the ravine we finally emerged from the timber 

 and found ourselves on the bald, rocky head of the mountain, 

 where no trees grow, for after leaving the fringe of gnarled,
