They both turned to look at the king of day as though understanding that the Indian artist meant to call their attention that way.
"Well," remarked Sandy, "the old fellow does look angry this morning. And then the sky all around has a coppery hue. That must mean more dry weather, brother."
But Bob shook his head. He had seen something more in those queer picture paintings that caught his attention.
"No, I think you are wrong, Sandy," he observed slowly. "See, here is what he surely means for rain pouring down. And further along is what must be the river rushing along, bank-full. I begin to see what it is, brother."
"A warning to the white settlers?" said Sandy quickly.
"What else can it mean? And look at this figure standing here; what do you make of him?" asked the other, pointing.
"Oh! I know!" cried Sandy, his face lighting up. "See how he is decked out with all sorts of things, bells and such! And in his hands he holds gourds that contain dried beans, to rattle when he shakes them. Yes, that must be the old medicine man I told you about. But what has he got to do with the rains?"
"Now I understand it all," declared Bob, with a smile.
"Then I wish you would tell me," remarked his brother, "for to tell the truth I don't seem able to grasp it."
"The old medicine man has been talking again with the Manitou," said Bob, "and has learned that the rain will soon come along, making a flood of the river. Perhaps he knows this from some sign, like the angry sun; but he pretends that the information was given to him from the Great Spirit."
