exceedingly cold from the sudden decrease of the temperature.
31st.] We moved onwards a few miles, but encamped at an early hour.
September 1st.] We proceeded about 10 miles over wooded hills, with the expectation of soon arriving at the Salt river, which we imagined to lie before us, either to the west or south-west, but were entirely deceived, and my companion now appeared to be ignorant of the country.
