Excerpts from the novel:
The horses brought an excellent price; they were young, perfectly matched, and spirited, yet gentle. Parting from them was perhaps the hardest pang Barbara had to endure. Castor and Pollux were really her friends—as, indeed, any animal she came in contact with was sure to be. But she derived a grain of comfort from the promise, which she went personally to obtain from their new owner, that even if they began to break down he would never allow them to be sold into hardship—a promise which, it is to be hoped, was kept for the sake of the girl who had tried to protect the creatures she loved.
