It was all dark and still in the car, and nobody came in, but the noise kept up outside, and I knew something had gone wrong with the train.

Perhaps Miss Laura had got hurt.

Something must have happened to her or she would come to me.
I barked and pulled at my chain till my neck was sore, but for a long, long time I was there alone.

The men running about outside must have heard me.

If ever I hear a man in trouble and crying for help I go to him and see what he wants.
After such a long time that it seemed to me it must be the middle of the night, the door at the end of the car opened, and a man looked in "This is all through baggage for New York, miss," I heard him say; "they wouldn't put your dog in here." "Yes, they did I am sure this is the car," I heard in the voice I knew so well, "and won't you get him out, please?
He must be terribly frightened." The man stooped down and unfastened my chain, grumbling to himself because I had not been put in another car.
