had walked the whole distance through this defile, 
which is known as the Guadalupe Pass, reaching this 
point inadvance. When all had come up, both men and 
animals were glad to hear the order to unhitch the 
mules and encamp for the night, which we did near a 
small rivulet, though our day’s journey could hardly 
have exceeded twelve miles. 
For the last three days we have noticed the tracks 
of several mules, all of which were shod, accompanied
