So Ramon, after a little, stole away to his own camp quite satisfied.
The next night, when he stood in the shadow of the rock ledge and waited, he was not startled by the unexpected presence of the person he wanted to see.

For although Bill Holmes came as cautiously as he knew how, and avoided the wide, bright-lighted stretches of arroyo where he would have been plainly visible, Ramon both saw and heard him before he reached the ledge.

What Ramon did not see or hear was Annie-Many-Ponies, who did not quite believe that those two wished merely to talk about a silver bridle, and who meant to listen and find out why it was that they could not talk openly before all the boys.
Annie-Many-Ponies had ways of her own.

She did not tell Ramon that she doubted his word, nor did she refuse to deliver the message.

She waited calmly until Bill Holmes left camp stealthily that night, and she followed him.
