Pretty soon it was spring, and sunny and pleasant and lovely, and the sweet mother and the children patted me and the puppy good-by, and went away on a journey and a visit to their kin, and the master wasn't any company for us, but we played together and had good times, and the servants were kind and friendly, so we got along quite happily and counted the days and waited for the family. And one day those men came again, and said, now for the test, and they took the puppy to the laboratory, and I limped three-leggedly along, too, feeling proud, for any attention shown to the puppy was a pleasure to me, of course. They discussed and experimented, and then suddenly the puppy shrieked, and they set him on the floor, and he went staggering around, with his head all bloody, and the master clapped his hands and shouted: “There, I've won--confess it! He's a blind as a bat!” And they all said: “It's so--you've proved your theory, and suffering humanity owes you a great debt from henceforth,” and they crowded around him, and wrung his hand cordially and thankfully, and praised him. But I hardly saw or heard these things, for I ran at once to my little darling, and snuggled close to it where it lay, and licked the blood, and it put its head against mine, whimpering softly, and I knew in my heart it was a comfort to it in its pain and trouble to feel its mother's touch, though it could not see me. Then it dropped down, presently, and its little velvet nose rested upon the floor, and it was still, and did not move any more. Soon the master stopped discussing a moment, and rang in the footman, and said, “Bury it in the far corner of the garden,” and then went on with the discussion, and I trotted after the footman, very happy and grateful, for I knew the puppy was out of its pain now, because it was asleep. We went far down the garden to the farthest end, where the children and the nurse and the puppy and I used to play in the summer in the shade of a great elm, and there the footman dug a hole, and I saw he was going to plant the puppy, and I was glad, because it would grow and come up a fine handsome dog, like Robin Adair, and be a beautiful surprise for the family when they came home; so I tried to help him dig, but my lame leg was no good, being stiff, you know, and you have to have two, or it is no use. When the footman had finished and covered little Robin up, he patted my head, and there were tears in his eyes, and he said: “Poor little doggie, you saved _his _child!”
