July 31.—Having remained all day in camp to rest the party, I found that the horses had again made a great diminution in the depth of the water in the rock, I therefore had the drays all prepared in the evening, intending to move away to the other water–course in the morning; but the next day the horses had unfortunately strayed, and it was late before they were brought up, so that we could not get away. Upon watering them when they arrived, I found that less impression was made upon the water than on the previous days; and after an anxious consultation with my overseer, I decided upon leaving the party in camp at Depot Pool until I could reconnoitre further north and return.
