'And you think that—'

'I think that Indians are not far away, and that—but come, let us saddle our mules and be off.'

It was high time, for at that very moment over a dozen pairs of fierce eyes were watching them from the cactus jungle. Spears were even poised ready for an attack, and only perhaps the sight of that ferocious-looking dog restrained them.

No one could come more speedily to a conclusion than Moncrieff. He hardly waited to hear Dugald's story before he had summoned Yambo, and bade him get ready with five trusty Gauchos to accompany them to the hills.

'Guns, señor?'

'Ay, guns, Yambo, and the other dog. We may have to draw a trigger or two. Sharp is the word, Yambo!'

In two hours more, and just as the winter's sun was at its highest, we all reached the cactus near the old monastic ruin. Here a spear flew close past Moncrieff's head. A quick, fierce glance of anger shot from the eyes of this buirdly Scot. He called a dog, and in a moment more disappeared in the jungle. A minute after there was the 243 sharp ring of a revolver, a shriek, a second shot, and all was still. Presently Moncrieff rode back, looking grim, but calm and self-possessed.

There was no one near the ruin when we advanced, but the Indians had been here. The grave was a grave no longer in shape, but a huge hole.

'Set to work, Yambo, with your men. They have saved us trouble. Dugald and Archie and Donald, take three men and the dogs and scour the bush round here. Then place sentinels about, and post yourselves on top of the red dune.'

Yambo and his men set to work in earnest, and laboured untiringly for hours and hours, but without finding anything. A halt was called at last for rest and refreshment; then the work was commenced with greater heart than ever.
