it was quite impracticable to move on the party until after having
previously ascertained where they could be taken to with safety. Upon
examining the barometers to-day, I was much concerned to find that they
were both out of order and useless; the damp had softened the glue
fastening the bags of leather which hold the quicksilver, and the
leathers that were glued over the joints of the cisterns, and so much of

other I could not get repaired in a satisfactory manner, not being able,
after all my efforts, to get rid of some small air bubbles that would
intrude, in spite of every care I could exercise.

August 2.--Leaving early, I took with me a native boy, and a man on

advancing. In following down the Depot watercourse to the plains, we
found a fire where the natives had encamped the previous night. This
surprised us, because we were not aware that there were any so

vigilance and circumspection in our future movements.

however, in the plains, we were fortunate enough to discover a puddle of
rain water, and at once halted for the night, though the feed was
indifferent. We had travelled twenty-eight miles, and the pack-horse
