"Whaur hae the black deevils gaun to?" Mac demanded indignantly, as if a considerable breach of etiquette had been committed by the rapid flight of our prospective hosts.

Then Stewart proceeded to poke among the scattered ashes, and soon discovered several still glowing logs well sunk beneath the surface. "Mac," said he solemnly, when we clustered round to examine his find, "we'll hae tae ca' canny; the deevils are no defeecient in strategy, an' it's plain they dinna want oor guid company."

Stewart was right; the blacks must have observed our approach, and being unwilling to meet us, had hastily decamped, first taking care to cover up any clue that might have aroused our curiosity. "That field-glass of yours has done good work, Phil," I said, when we turned away. "If you had not noticed the smoke we should never have dreamed that there had been any one here for at least a year, and goodness knows what might have happened if we had gone to sleep in this district without keeping a watch."

Mac chirruped to his patient charge. "Gee up, Slavery," said he, "ye'll get a drink the nicht."

In spite of our most strenuous efforts, however, we were unable to reach the timber belt that day, and darkness closed over and compelled us to camp while we were yet a good way out in the open. For the last several miles the camels had literally to be dragged over the ground by a constant pressure on their nose ropes, and when we halted our weary caravan and unloaded the suffering beasts, they sank upon their knees breathing heavily, and made no attempt to search for anything to eat. It was plain that, should another day pass without water being discovered, our four-footed companions must give up the struggle, which in turn would mean that we should all be doomed to a most unenviable fate.

"Ma puir animile," said Mac, stroking "Slavery's" quivering nostrils, "ye've been nine days withoot a drink, but ye'll get a' ye can tak' the morn."

"Slavery" seemed almost to understand the sympathetic words, and grunted feebly in reply; then I was surprised to see him struggle to his feet and proceed to feed on the spinifex tufts growing around.

"He kens I'm tellin' the truth!" shouted Mac delightedly; and there was much joy among us when "Misery," determined not to be outdone, after several efforts succeeded in rising shakily and joining his neighbour.

"There's life in auld 'Misery' yet," applauded Stewart with hearty satisfaction; and the wonderful endurance shown by the dumb animals made me somewhat ashamed of my own collapsing resolution.

"Let's be happy, boys," counselled Phil in most lugubrious tones. "Life is short, you know, and we'll be a long time dead."
