sap. On one estate near Petorca they tried to count them,

It was indeed a black man, as we saw when the moon came out of a cloud. His head was on his breast, and he walked round the fire with measured, regular steps. At intervals he would stop and raise both hands to the sky, and bend his body in the direction of the moon. But he never uttered a word.

'It's magic,' said Archie. 'He's going to raise Satan. We must bide here and see what happens, for he'll grip us if we try to go back. The moon's ower high.'

The procession continued as if to some slow music. I had been in no fear of the adventure back there by our cave; but now that I saw the thing from close at hand, my courage began to ebb. There was something desperately uncanny about this great negro, who had shed his clerical garments, and was now practising some strange magic alone by the sea. I had no doubt it was the black art, for there was that in the air and the scene which spelled the unlawful. As we watched, the circles stopped, and the man threw something on the fire. A thick smoke rose of which we could feel the aromatic scent, and when it was gone the flame burned with a silvery blueness like moonlight. Still no sound came from the minister, but he took something from his belt, and began to make odd markings in the sand between the inner circle and the fire. As he turned, the moon gleamed on the implement, and we saw it was a great knife.

We were now scared in real earnest. Here were we, three boys, at night in a lonely place a few yards from a savage with a knife. The adventure was far past my liking, and even the intrepid Archie was having qualms, if I could judge from his set face. As for Tam, his teeth were chattering like a threshing-mill.

Suddenly I felt something soft and warm on the rock at my right hand. I felt again, and, lo! it was the man's clothes. There were his boots and socks, his minister's coat and his minister's hat.

This made the predicament worse, for if we waited till he finished his rites we should for certain be found by him. At the same time, to return over the boulders in the bright moonlight seemed an equally sure way to discovery. I whispered to Archie, who was for waiting a little longer. 'Something may turn up,' he said. It was always his way.

I do not know what would have turned up, for we had no chance of testing it. The situation had proved too much for the nerves of Tam Dyke. As the man turned towards us in his bowings and bendings, Tam suddenly sprang to his feet and shouted at him a piece of schoolboy rudeness then fashionable in Kirkcaple.

'Wha called ye partan-face, my bonny man?' Then, clutching his lantern, he ran for dear life, while Archie and I raced at his heels. As I turned I had a glimpse of a huge figure, knife in hand, bounding towards us.
