Pinky was very anxious to go, but where he went he did not care. He left the trail almost at once and cantered through a pasture where the scattered clumps of brush and greasewood soon hid him and his rider from the sight of anybody on the wagon-trail. At least, they were quite hidden from Russ Bunker when he rode back to look for his sister.

Rose did not at first worry at all about where she was or where Pinky was taking her. She listened for the expected "boom!" of the dynamite explosion. But as minute after minute passed and the explosion did not come, Rose began to wonder if she had made a mistake.

Pinky kept right on moving, just as though he knew where he was going and wished to get there shortly. But when Rose looked around she knew she had never been in this place before. And, too, she discovered that Russ had not followed her.

This last discovery made Rose pull up the pony and think. It alarmed her. She was not often frightened when Russ was by, although she had given way to fright on this particular occasion. But she knew she would not have been afraid had her brother been right here with her.

As it was, Rose was very much frightened indeed. She did not know where Russ was, nor did she know where she was. Therefore it was positive that she was lost!

Now, Pinky was a very intelligent pony, as was afterward proved. You will read all about it later. But he could not know that Rose wished him to find his way home unless she told him as much. And that Rose did not do.

She just burst out crying, and the pony had no idea what that meant. He turned to look at her, tossed his head and pawed with one dainty hoof. But he did not understand of course that the girl on his back was crying because she was lost and was afraid.

Perhaps, too, if Rose had let the bridle-reins alone Pinky would have remembered the corral and his oats and have started back without being told that the ranch house was the thing Rose Bunker most wanted to see. But the little girl thought she had to guide the pony; so she grabbed up the reins at last and said:

"Come up, Pinky! We have just got to go somewhere. Go on!"

Pinky naturally went on the way he was headed, and that chanced to be in a direction away from Cowboy Jack's home, where the Bunkers were then visiting. Nor did the pony bear her toward the place where the moving picture company was at work.
