By this time our young friends had reached the foot of the ridge, on whose top it had been agreed they were to say farewell to one another; and the thought of the nearness of the parting was suddenly pressed home to each heart, and they rode to the top of the ridge without speaking a word. Here they pulled up their horses; and, for a moment, their eyes looked wistfully into one another's faces, while they sat silent in their saddles.
"Oh, come, let's have the agony over!" and Bud tried to make his voice sound cheery and unconcerned. "Good-by, Ruth," and, urging his horse up close to the side of his sister's horse, he leaned over, threw his arms around her neck and kissed her. Then he turned and quickly served Iola in the same way; and, striking spurs into his horse, started off, his pack-horse tugging at the rope behind him.
Thure hesitated a moment; and then, following Bud's example, quickly kissed Iola and Ruth good-by, and started after Bud.
"Don't forget that you have promised me the first gold nugget that you pick up in the cave!" called Ruth.
"Nor the gold necklace!" warned Iola.
Thure and Bud waved their hands and shouted in reply; but rode steadily on.
The two girls sat on their horses and watched them, until, with final shouts and the waving of their hats, they passed over the top of a distant ridge and vanished from sight. Then Iola and Ruth turned their horses homeward and rode silently down the other side of the ridge. They did not care to talk, even about the wonderful Cave of Gold, just then.
They had ridden something like a couple of miles on their way homeward and their tongues were just beginning to wag, girl-like, again, when both were considerably startled by a loud hallo, coming from behind. They turned quickly and saw two horsemen, who had just ridden out from behind a small grove of trees, some twenty rods back and to the right, and who were now riding toward them.
"I wonder who they can be!" exclaimed Ruth. "I am sure that I never saw them before; but I suppose we had better wait and find out what they want. They might be lost. They look like strangers to this part of the country," and she pulled up her horse.
"Yes," agreed Iola, halting her horse by the side of Ruth. "They are probably foreigners on their way to the mines; and we had better wait to see if we can be of any help to them."
