Thursday, 15th July, Mulga and Gum Creek. Left the camp at 9 a.m. on a bearing of 190 degrees for two miles, thence 230 degrees for one mile and a half, thence 250 degrees for four miles and a half, thence 286 degrees for two miles, thence 290 degrees for one mile, thence 270 degrees for five miles, thence 320 degrees for one mile, to camp at some mallee. The country on both sides of the creek is good, but subject to be flooded; the width of the plain is about fifteen miles, bounded on the south side by bare stony rises, and on the north by scrubby rises. The creek spreads itself all over the plain, which seems to be very extensive. It has been excessively cold to-day: wind from the west. Distance to-day, seventeen miles.
