This section of the book is from the "Stories of Animal Sagacity" book, by William Henry Giles Kingston.
A terrier, which lived at Dunrobin Castle many years ago, had a family of puppies, which were taken from her and drowned. How she mourned for her offspring, and wondered why her owner had been so cruel as to allow them to be earned away! Her maternal feelings were as strong as those of other creatures, and she felt a longing to exercise them. At length she caught sight of a brood of young ducklings. They were young, and required care just like her own dear little whelps; so, seizing them, she carried them off one by one to her kennel, and would allow no one to take them away. They seemed to understand that they had obtained a very good nurse, and she watched them with the most affectionate care. When, however, they made their way to the water and plunged in, she exhibited the greatest alarm, believing that they would be drowned, as her own puppies had been. No sooner had she reached the shore than she picked them up in her mouth, and carried them off to her kennel, resolving, probably, never to allow them to run into the same danger again.
After the ducklings grew up, and were no longer willing to submit to her canine style of nursing, she again became the mother of another litter. On this also being destroyed, she seized two cock chickens, which she reared with the same care that she had done the ducklings. When, however, the young cocks began to try their voices, their foster-mother was as much annoyed as she had been by the ducks going into the water, and invariably did her best to stop their crowing.
You will never want objects on which to exercise your kind feelings. “The poor you have always with you.” You must not be disheartened or dissatisfied if they persist in following a different course from that which you think they ought to do. How often, when a baby, have you cried lustily when your mother or nurse heartily wished you to be silent; and as you grew older, perversely ran away into danger when they called after you! Through life remember that little terrier, and like her persevere in befriending those in need.
