Hitherto their progress had been slow and discouraging. They had travelled 1,700 miles, but were yet at no great distance from Alice Springs. Nor was the outlook any more encouraging. Day after day it was the same weary journeying over spinifex ridges and sandy valleys, without any indication of the fine country they had hoped to discover; but, to their credit be it said, no one even hinted about giving up the enterprise. By the 17th of August a notable stage in their progress was reached. Warburton ascertained that he could not be more than ten miles distant from the most southern point reached by Mr. A. C.
