On the same errand Mr. Frederick Walker, Commander of Native Police, was sent from Rockhampton to the Albert River by the Queensland authorities. Taking a party of mounted troopers, he proceeded to Bauhinia Downs, on the Dawson, where the expedition was finally organized on the 7th September, 1861. The River Nogoa was reached on the 16th, after which he pushed on through Walker's Pass to the River Nivelle. By the 27th he had made the Barcoo, which was followed down for three days, during which traces both of Gregory and Leichhardt were discovered. From the Barcoo a passage was made to the Alice through much spinifex country. After crossing the watershed between the Alice and the Thomson, a fine tributary of the latter, called the Coreenda, was met with. By the 16th of October they had got into a country of high mountains, where the natives were observed to be armed with iron axes and tomahawks. Some traces of Leichhardt were also found in this quarter. The advance was now continued through a hilly country in a north-west direction to lat. 21°, where they fell in with the head-waters of the Barkly, a large tributary, or a main section, of the Flinders River, which led them through splendid country. Another fine tributary of the Flinders was soon after discovered, and called the Norman, in honour of the captain of that name who was in command of the depôt on the Albert. Nothing further of special interest occurred till the 30th of October, when they were attacked by a large party of armed natives. Walker commanded his men to fire upon them, when a dozen of these unfortunate creatures fell under his guns. There is reason to fear that the leader's experience as an officer of black troopers had led him to hold the lives of the aborigines too cheap and to forget that they were human beings, of the same blood and brotherhood as ourselves. The explorers now followed the Norman River, but had to dig in its channel for water. On the 25th of November they reached the junction of the Norman and the Flinders, the latter of which being a large and beautiful river. Here the track of Burke and Wills was discovered, leading south, but could not be followed till fresh supplies were obtained from the depôt on the Albert. Early in December the expedition came on to the Leichhardt, and then to the Albert River, the latter flowing over plains and flooded low flats, where the tracks of several other explorers were seen. On the 7th the depôt was reached and found to be under the superintendence of Captain Norman. Walker had thus made the journey in three months and twelve days from Rockhampton. In point of celerity, our annals of exploration contain nothing to beat this record. After passing thirteen days at the depôt, Walker started anew to follow up the track of Burke and Wills which he had been fortunate enough to discover. He succeeded in running it southward to the ninth camp of the missing expedition,
