Towards evening, one of the horses having broken his hobbles, and got alarmed, galloped off, taking the other with him.

Tired and wet as I was, I was obliged to go after them, and it was some miles from the camp, before I could overtake and turn them back.

Our latitude was 30 degrees 55 minutes S.
July 15 .-- This morning was misty and clondy, and dreadfully cold.

We set off early and commenced tracing up and examining as many of the watercourses as we could; we did not, however, find permanent water.
Under one low ridge we met with what I took to be a small spring emanating from a limestone rock; but it was so small as to be quite useless to a party like mine, though the natives appeared frequently to have resorted to it.

Finding the courses of the main channel become lost in its many branches, I ascended the dividing ridge, and crossed into the bed of another large watercourse, in which, after travelling but a short distance, I found a fine spring of running water among some very broken and precipitous ranges, which rose almost perpendicularly from the channel; in the latter, high ledges of a slaty rock stretched occasionally quite across its bed, making it both difficult and dangerous to get our horses along.
