"But, of course, not being fish, we cannot get down into the hole to see whether or not there is gold in it, as long as the water runs over it; and so we are making this wing dam up here above the elbow, to turn the stream into a new channel and send it flowing kitti-corner-wise across the opening between the two arms of the elbow and back into its own channel below the elbow, which, of course, would leave the elbow dry and give us a chance to clean out the hole and get all the gold there is in it." "Oh, I see now!" exclaimed Thure, his eyes beginning to shine with excitement. "And you call it a wing dam, because you have to make a sort of a wing to the main dam, extending for quite a ways out on the dry land, in order to give the water a sufficient turn to keep it from flowing back into the old channel until you are ready to have it." "Exactly," and Mr. Conroyal smiled. "And, if the good Lord will only keep it from raining until we get the dam finished, all of us might make our fortunes right here; and, again, we might not find a cent's worth of gold. It's all a speculation," and he shrugged his big shoulders. "But--but what difference could a little rain make? You are not afraid of getting wet, are you?" and Thure smiled at the thought of these hardy men standing in dread of a little rain. "No, son, we are not afraid of getting wet," and Mr. Conroyal smiled grimly. "But a big rain up there in the mountains where this stream comes from, would mean that in less than no time a flood of water would come a-tearing down this narrow gulch that would sweep our dam off its feet quicker than you could wink an eye--and us along with it, if we didn't get out of here about as lively as the Lord would let us. Howsomever we are not counting much on a rain, seeing that the dry season has got a fairly good start; but it might come," and his eyes turned a little anxiously toward the snow-covered mountains to the northeast, whence came the little stream of water running through Holt's Gulch. "But, come, we must get busy. Now, the first thing for us to do is to figure out about how much longer it will take us to finish the dam. I calculate that we have the dam about two-thirds done; and, since we have now been at work twelve days, I think we can count on finishing it in another six days." "That's 'bout my idee, Con," agreed Ham. "Another six days otter see th' finish of th' job; an' then--maybe it will be gold an' maybe it will be jest a lot of durned hard work for nothin'; but it shore looks good; an' I'm in favor of seein' this dam through afore tacklin' th' Cave of Gold propersition."
