TO THE COPPER MINES. 231 
rance of the vegetation, together with the moisture 
which prevails in such mountainous regions, I have no 
doubt the experiment would be successful. 
We reached this district on the 2d of May. Vege- 
tation was then forward, though there had been no 
rain. But it must be remembered that during the

impassable for wagons, or even mules. The dry 
gullies became rapid streams, five or six feet deep, and 
sometimes fifty feet or more across. On this day, a

after rains, I found a fire quite agreeable. The party
