"Thunder-maker!" he exclaimed. "The treacherous hound! This is his work. I was wakened by something before. He must have been letting loose his vile creatures."

Just then the snakes returned unpleasantly near to the men's heads again, so further conversation was impossible, for it is remarkable what little sound will attract a serpent's attention, and the nature of a rattler is to regard every sound and movement as something dangerous to be fought.

For more than an hour the men lay in strained positions, watching the writhing movements of the ugly creatures, and wondering how long the position could be sustained.

And then, just when it seemed that the situation could not be supported another minute, they became aware of a sound of soft whistling at no great distance from the rear of the tent. At first the sound was quite low, and barely audible, but gradually it increased in volume until it took the form of a sort of minor tune of barbaric rhythm played on some sort of reed instrument.

At the beginning the music was unheeded by the serpents, but as it became more distinct it was observable that the creatures became restless and uneasy. Now and then one would raise its head and begin to sway gently to and fro, in agreement with the rhythm. But gradually each seemed to be irresistibly drawn towards the back of the tent, as the spell of their master's music fascinated them. One by one they passed in one direction—moving slowly yet steadily in obedience to the call.

And as the last of the reptiles passed beneath the edge of the tent-cloth both men sprang from their couches and rushed round to the teepee that was pitched a little way behind their own.

But they found Thunder-maker reclining on a heap of robes and apparently asleep; and not a sign was seen to suggest the presence of a "rattler."

So much for the art of the snake-charmer and the craft of an evil man.
