For some seconds Dick stood in front of Arthur, pointing his finger straight at him, while Arthur sat there in silence gazing steadfastly at Dick. Suddenly, the young Spaniard jumped up, stepped forward, and slapping my partner on his chest with the back of his hand, exclaimed:

"Look here, old man! I believe you are right. I believe there is a stream somewhere which those old Pueblos used for irrigating their farms. It has somehow been switched off and lost. It ought to be found and brought back. Now, look here! I can't stay here to hunt for it myself: I must get home right away. But I'll make a bargain with you:—You find that stream and provide a way of getting the water back to Hermanos, and I'll give you a half-interest in the grant—when I get it. There, now! There's a chance for you!"

"Do you mean that?" cried my partner.

"I certainly do," replied Arthur. "The grant is without value as it stands: if you can get water on to it and give it a value, it would be only just that you should have a share in the profits. Yes, I mean what I say, all right. If you'll supply the water, I'll supply the land. There! What do you say? Is it a bargain?"

For a moment Dick stood staring thoughtfully at our friend, and then, turning to me, he exclaimed sharply:

"Frank! Let's do it! Here we are, out for the summer. It's true we came out to hunt for a copper mine, but that scheme being 'busted' at the very start, let us turn to and hunt for water instead. What do you think?"

"I'm agreed!" I cried.

"Good! Then we'll do it! And the very first move——"

"The very first move," interrupted Arthur, laughing, "the very first move is—to bed! It's after eleven!"
