"I'm sorry he killed the horse," said Donald. "We need him."
"Perhaps he didn't," suggested Adrian. "Suppose we ride over and see."
Suiting the action to the word, the boys rode out into the open, much to the newcomer's surprise and consternation.
"Señors," he exclaimed, as he came running toward them, "I am sorry I had to hurt your horse; but I couldn't lose my brother."
"Your what?" asked Billie.
"My brother. My little brother. Could I, Ambrosio?" and he patted the ape on the cheek.
"What do you call him?" asked Donald.
"I call him Ambrosio because he is so sweet."
"Bah!" exclaimed Billie. "I called him Ab, but he ought to be named Diabolo. But how about the horse?"
"I am afraid I have rendered him quite useless for the present, Señor. I may have broken his leg."
