"It's Old Billee," answered Bud. "He's going to be with us out at Flume Valley. Did dad tell you of the new venture?" he asked his cousins.

"Yes, and it sounds good. Must have been quite a trick to bring water from Pocut River, Bud."

"Well, it would have been if Professor Wright hadn't showed dad how to use an old underground water course for part of the way. Then it was easy. And say—you ought to see what a difference water has made in that valley! It was almost a desert before we irrigated."

"I'm anxious to see it!" said Nort.

"We can't get there any too soon to suit me," added Dick. "Just think! We're going to be our own bosses—boy ranchers for fair!"

"You intimated plenty that time!" cried Bud. "Well, let's hit the trail!"

The three boy ranchers started off, Nort and Dick accompanying Bud back over the way the latter had come. As they rode up the hill Old Billee passed on down another trail, leading to Diamond X proper.

"Howdy, boys!" called the old cowboy from the distance to Nort and Dick. "See you a bit later over at your own ranch!" he added, and then, with a friendly wave of his hand, he went down into a little swale, or valley, and was lost to sight.

"Now for some good times!" cried Bud, as he rode between his two eastern cousins, who had again come to spend the summer with him in the great western outdoors.

"If it's anything like last year we sure will have a bang-up vacation!" declared Nort.
