"Goo-day," he said, with a grin of delight at being noticed; but he at once became serious, and continued, speaking especially to Sax: "Me go 'way.... Me come back by'm by."

"Going away?" asked Sax. "Whatever for?"

"Me walk longa Musgraves.... Me come back by'm by," he repeated.

"But what'll Mick say?" asked Vaughan.

"Mick good fella," said the native simply. "Him real good fella, quite.... Him only little time boss longa me. Boss alday longa me (my real boss) sit down over dere," he pointed to the Musgrave Range. "Me yabber Boss Stobart." He said the name with pride.

"I'll go with you," said Sax, starting up as if he meant to set out immediately. "I'll go with you to find my father."

"By'm by," replied Yarloo. "White boy come by'm by. No come now. S'pose white boy come now, Boss Stobart, rouse like blazes (would be very angry). White boy sit down little time. Me come back by'm by."

"Well, at any rate, I'll send Father a note," said Sax, and he ran to Government House to get a pencil and some paper. He found an old diary, and tore a sheet out of it and wrote: "We're at Sidcotinga Station. I wanted to come out to you, but Yarloo would not let me. Tell him that we may come out. Love from Sax."

He ran back to the horse-gear room, but Yarloo had gone. The boy had evidently not understood what Sax meant and had already started out for the Musgrave Ranges. It was a great disappointment to the boys not to be allowed to go straight away and find the white drover, yet they had already experienced enough, both of the hatred of the Musgrave tribes and of the power of the desert, to convince them that they had better take the advice of those who knew the conditions so much better than they did. They talked a lot about the ranges which appeared to be so near, seen through the clear dry air, and they went over and over again the message which they had received in Oodnadatta from Boss Stobart, trying to find an explanation for the mystery.

"In difficulties. Musgrave Ranges. Tell Oodnadatta trooper, but no one else. He'll understand. Boy quite reliable. Don't worry. Get a job somewhere. "STOBART."
