"He is trying it by his universal test--his all-sufficient crucible," said the Doctor. "Everything must go into that mouth. It is his only medium for acquiring knowledge at present. If it was large enough and he could reach far enough, he would investigate the nature of the solar system by means of it. It is lucky for the world that he is not sufficiently big to put the sun in his mouth. We should certainly find ourselves in darkness--not to mention that he might burn himself. My dear, I am afraid he will swallow some of the leaves," he added. "We must interfere. This is one of the emergencies when a grandfather has a right to exercise authority." The rose was gently detached from Ravvie's fat grasp, and stuck in his little silk bonnet, his eyes following it till it disappeared. "You see he is an eating animal," continued the Doctor. "That is pretty much all at present, and that is enough. He has no need of any more wisdom than what will enable him to demand nourishment and dispose of it; and God, in his great kindness towards infants, has not troubled him with any further revelations so far. God has provided us to do all the necessary thinking in his case. The infant is a mere swallower, digestor, and assimilator. He knows how to convert other substances into himself. He does it with energy, singleness of purpose, perseverance, and wonderful success. Nothing more is requisite. In eating he is performing the whole duty of man at his age. So far as he goes he is a masterpiece." "But you are making a machine of him--an oyster," protested Lillie. "Very like," said the Doctor. "Very like an oyster. His existence has a simplicity and unity very similar to that of the lower orders of creation. Of course I am not speaking of his possibilities. They are spiritual, grand, perhaps gigantic. If you could see the inferior face of his brain, you would be able to perceive even now the magnificent capacities of the as yet untuned instrument." "Oh don't, papa!" implored Lillie. "You trouble me. Do they ever dissect babies?" "Not such lively ones as this," said the Doctor, and proceeded to change the subject. "I never saw a healthier creature. I shouldn't wonder if he survived this war, which you used to say would last forty years. Perhaps he will be the man to finish it." "I don't say so now. I didn't think my husband would be on the Union side when I said that. I think we shall beat them now." "Since the miracle all other things seem possible," philosophised the Doctor.
