The explorations of Mr. John McDouall Stuart may truly be said, without disparaging his brother explorers, to be amongst the most important in the history of Australian discovery. In 1844 he gained his first experiences under the guidance of that distinguished explorer, Captain Sturt, whose expedition he accompanied in the capacity of draughtsman. Leaving Lake Torrens on the left, Captain Sturt and his party passed up the Murray and the Darling, until finding that the latter would carry him too far from the northern course, which was the one he had marked out for himself, he turned up a small tributary known to the natives as the Williorara. The water of this stream failing him, he pushed on over a barren tract, until he suddenly came upon a fruitful and well-watered spot, which he named the Rocky Glen. In this picturesque glen they were detained for six months, during which time no rain fell. The heat of the sun was so intense that every screw in their boxes was drawn, and all horn handles and combs split into fine laminae. The lead dropped from their pencils, their finger-nails became as brittle as glass, and their hair, and the wool on their sheep, ceased to grow. Scurvy attacked them all, and Mr. Poole, the second in command, died. In order to avoid the scorching rays of the sun, they had excavated an underground chamber, to which they retired during the heat of the day.
