At Hall's Creek Carnegie heard of the misfortune that had befallen Wells, in the loss of two of his party, and he at once volunteered his assistance; but as search-parties had already started out, his aid was not required. He therefore rested for a short time before again trying conclusions with the desert on the return journey. Sturt's Creek was by this time occupied and stocked, and the party followed it down until they arrived at its termination in Gregory's Salt Sea. From this point Carnegie kept a southerly course to Lake Macdonald near the South Australian border, passing on his way a striking range which he named the Stansmore Range, after his unfortunate companion. Lake Macdonald was long thought to be a continuation of Lake Amadeus, until the exploration of Tietkins in 1889 proved its isolation. From Lake Macdonald, Carnegie, who had now three horses in his equipment, kept a more south-westerly course towards the Rawlinson Range, the endless sand-dunes still crossing his track in dreary succession. So persistently did they rise across his path that, on one day, eighty-six of them were crossed by the caravan during a progress of eight hours. From the Rawlinson Range they kept on the same south-west course until they struck their outward track at Alexander Spring. A fall of rain fortunately replenished the spring shortly after the arrival of the party. They reached Lake Darlot on the 15th of July, and their desert pilgrimage was ended. Not only did Carnegie get safely across the dreaded desert, but he returned overland to his starting-point by a different route. He wrote a book, Spinifex and Sand, which contains a most interesting account of this journey, as well as a graphic and picturesque description of the physical features of the Great Sandy Desert. Carnegie died before he had made more than this one contribution to Australian geography. Like the ill-fated Horrocks, he had the explorer's ardent spirit. His restless and adventurous soul ever leading him onward to the frontiers of settlement and the outskirts of civilised life, he fell beneath a shower of poisoned arrows at Lokojo in Nigeria, on the west coast of Africa, on the 27th of November, 1900. 20.4.
