This is a dog story book. Rover was a grand old dog, large and strong enough to carry a much heavier miss than Jessie. He was good-natured too. Still he had no notion of being used for a pony. So, after standing quite still for a moment or two, he suddenly started and sent Jessie sprawling on the piazza, while he trotted down the steps and made a bed for himself in the greensward, on the lawn, as quietly as if nothing had happened. A knowing old dog was Rover. Jessie picked herself up and began singing again. Scarcely had she trilled out two lines before she saw Guy coming towards the house.
