TO EL PASO, . Bol 
I first went to Mr. Flotte’s mine. I presented my 
letter of introduction to the superintendent, a native 
Castilian, and was received by him with the politeness 
that characterizes his countrymen. After sitting a 
short time in his house near the entrance, we were 
each provided with torches; whereupon we descended 
the mine, following the footsteps of our guide, the super-

late rains. The shaft was between six and seven feet 
high, branching off in various directions. We traced 
it to its bottom, which was eighty varas, or about 240

son, and even then contains but little water. Half a 
dozen walnut trees of a small size, grow upon its 
banks, whence its name. After crossing this rivulet,
