easy stages to the head of the Bogan River, which had been partly traversed the year before by surveyor Dixon.  It was during this expedition that Richard Cunningham, brother of Allan, was murdered by the natives.  He had not been long in Australia, and had been appointed botanist to the expedition.  On the morning of April 17th, he lost sight of the party, whilst pursuing some scientific quest, and as the main body were then pushing hurriedly over a dry stage to the Bogan River, he was not immediately missed.  Not having any bush experience, he lost himself, and was never seen again.  A long and painful search followed, but owing to some mischance, Cunningham’s tracks were lost on the third day, and it was not until the 23rd of the month that they were again found.  Larmer, the assistant-surveyor, and three men were sent to follow them up until they found the lost man.  Three days later they returned, having come across only the horse he had ridden, dead, with the saddle and bridle still on.  Mitchell personally conducted the further search.  Cunningham’s tracks were again picked up, and his wandering and erratic footsteps traced to the Bogan, where some blacks stated that they had seen the white man’s tracks in the bed of the river, and that he had gone west with the Myalls, or wild blacks.*

[Footnote.] Lieutenant Zouch, of the Mounted Police, subsequently found the site of his death, and recovered a few bones, a Manilla hat, and portions of a coat.  The account afterwards given by the natives was to the effect that the white man came to them and they gave him food, and he camped with them:  but that during the night he repeatedly got up, and this roused their fears and suspicions, so that they determined to destroy him.  One struck him on the back of the head with a nulla-nulla, when the others rushed in and finished the deadly work.

As is often the case with men lost in the bush, the unfortunate botanist, by wandering on confusing and contradictory courses, had rendered the work of the search party more tedious and difficult, thus sealing his own fate.  A rude stone memorial has since been erected on the spot, and a tablet put up in the St. Andrew’s Scots Church, Sydney.  The death of Cunningham, who was a young and ardent man with the promise of a brilliant future caused Mitchell much distress of mind.  He did all he could to find his lost comrade, and jeopardised the success of the expedition by the long delay of fourteen days.

He resumed his journey by easy stages down the Bogan, and on the 25th of May came to the Darling.  This river was at once recognised by all who had been with him on his former trip as identical with the Karaula as Mitchell had supposed; but he found the country in a different condition from that presented by it when Sturt and Hume first discovered the river at nearly the same place.  The water was now fresh and sweet to drink, and the flats and banks luxuriant with grass and herbage.
