Laughing Jack shook her head, crowned with gold brown hair; she was without a hat, after her old custom.

"You know the answer to that question as well as I do, Jim. Jimmie adores the ranch. He is named for you, and you have done everything in your power to make him love it. Then I must have implanted my own affection for the freedom of our western life in my little son. Jimmie insists that he wants nothing better in the future than to stay on here and run the ranch and the mine when you and I have grown too old to be troubled with such responsibilities. He is only eight years old at present and so we need not feel laid on the shelf at once."

"No, but I am not young as I was, Jack, hair is turning pretty gray these days," Jim Colter answered. "I have never mentioned this to the boy, but I have wanted the same thing he does. I would like Jimmie to live here and perhaps marry one of my four girls and keep the old ranch in the family through another generation or so. Sentiment of course, yet so far Jimmie is the only son on the horizon! Here I am with four daughters, Jean and Ralph Merritt with two, Olive and Captain MacDonnell with no children, and Frieda's and Professor Russell's little girl so frail that it is hard to count on any future for her."

At this Jack's expression clouded. A moment later she again arose in her saddle, this time pointing toward the eastern portion of the Rainbow ranch. To the west and north lay the gold mine discovered years before, though no longer yielding a supply of gold as in its early days.

The mine had never interested either Jacqueline Ralston or Jim Colter as it had the other members of the family. They had been horse and cattle raisers before a mine was ever dreamed of, and it was the rearing of the livestock for which Jim and Jack cared intensely to this day.

Riding through the ranch, every half hour or so they had passed a herd of cattle browsing amid the purple alfalfa grass, seen the sleek brown cows standing with their young calves close beside them. Less often they had run across a small drove of horses and young colts, as horses were no longer so good an investment as in the old days. Yet the present Rainbow ranch owners would prefer to have lost money than be without them, the horses having always received Jack's especial affection and attention as a girl and upon her occasional visits home to the ranch after her English marriage.

"Can that be a herd of horses or cattle stampeding there toward the east, Jim? We are too far off to see distinctly; suppose we ride in that direction," Jack said unexpectedly.

Wasting no time in words Jim Colter nodded. The following moment both horses, their noses pointing eastward, were galloping across the open prairie fields and away from the road.

Experienced ranchmen, he and his companion appreciated that the cloud of dust and the grouping of dark bodies advancing toward them with unusual rapidity represented trouble of some kind. At this time of the year it seemed scarcely possible that a wolf had stolen from the pack and frightened one of the herds. Yet there was no accounting for the tricks of nature. Moreover, frequently a number of horses or cattle suffered from group fear, the one transmitting the fright to the other without apparent reason.

Half a mile away the drove of young horses, which Jim Colter had finally located with his field glasses, turned and swerved south.
