The Chamberlain tried to explain, and was delighted to make a proposal to visit this exhibition. The Prince expressed his assent by a slight nod, looked at his watch, and went up to his room to go through his three hours' morning course: one for the science of politics, one for mythology and aesthetics, and one for tactics and strategy; then he accompanied his attendant to the exhibition. Even the Chamberlain was bored as he followed his young master through the great rooms, in which stood countless inexplicable machines. The agent of the manufacturers began his explanations; the Chamberlain asked such questions as would show a fitting love of knowledge; the Prince went patiently from one unintelligible object to another, and heard something of plows, scarifiers and rollers. At last, at the great threshing-machine, the expounder had to call a workman to bring a step-ladder, by ascending which they would be enabled to admire the internal mechanism. The Prince left this labor to the Chamberlain; played meanwhile with his lorgnette, and asked the agent, in the low tone in which he was wont to speak: "Have you any butter-machines?" "Yes," was the reply, "several different kinds." The Prince then quietly turned his attention to the great threshing-machine, and learnt to value the beautiful arrangement by which it threw out the straw into an invisible hayloft. At last they came to the row of machines on which he had set his heart--the modern successors of the old time-honored churn. There they stood beside each other--the little hand-chum, by which, if the assertion of the guide was to be trusted, a housewife could make her butter in an incredibly short time; and the great machine, which could work sufficient to supply the needs of the largest dairy. It was described to the Prince how the cream, when poured in, was put in quick circular motion, and how, as a result of this, the butter was separated from the milk. He had already heard this much more agreeably told; but it gave him pleasure to see the advantages of the modern invention, and he became thoroughly convinced of its superiority. To the astonishment of his attendant he asked intelligent questions, and took hold of the crooked handle, endeavoring to turn it a little, but withdrew his hand with an embarrassed smile. At last he inquired about the price. The Chamberlain had rejoiced at the laudable desire of knowledge which his young master had shown, but was much humiliated when the Prince turned to him and said, in French, "What do you think? I have a mind to buy this little machine." "For the sake of turning the handle," thought the Chamberlain, with an inward shrug of the shoulders. "How is it that your Highness takes an especial interest in this?" "It pleases me," replied the Prince, "and one ought to buy something of the man."
