"I do, sir, most heartily, most heartily," Jack said as he grasped the hand which Mr. Merton held out, but his voice quivered a little and tears stood in his eyes. "I am glad, indeed, although I shall miss you so terribly, you have been so good to me," and Jack fairly broke down now, and cried silently.
Mr. Merton put his hand on his shoulder: "Jack, my work is nearly done, so far as you are concerned. You have worked nearly as far as can be of any use to you in pure mathematics. For the next few months you may go on; but then you had better turn your attention to the useful application of what you have learned. You want to fit yourself to be an engineer, especially, of course, a mining engineer; still the more general your knowledge the better. You will have, therefore, to devote yourself to the various strains and stresses in iron bridges, and the calculation of the strength of the various forms of these structures. Then all calculations as to the expenditure of heat and force in steam engines will be quite material for you to master. In fact, there is work before you for another four or five years. But for much of this you will not require a master. You will find the practical part easy to you when you have a thorough knowledge of mathematics. At the same time if you will once a week send me your papers, noting all difficulties that you may meet with, I will go through them and answer you, and will also give you papers to work out."
"You are very, very kind, sir," Jack said; "but it will not be the same thing as you being here."
"No, not quite the same, Jack; still we can hardly help that."
"Oh, no, sir!" Jack said eagerly, "and please do not think that I am not glad to hear that you have got a place more worthy of you. It was a blow to me just at first, and I was selfish to think of myself even for a moment."
"Well, Jack, and now about this question of the soup dinner?"
"Oh! it does not matter, sir. I had forgot all about it."
"It matters a little, Jack, because, although I did not promise to keep silence, I should certainly have respected your wish, had it not been that it seemed to be a far more important matter that the truth should be known."
"More important, sir?" Jack repeated in a puzzled tone.
"More important, Jack. My successor has been chosen. He is just the man for this place—earnest, well trained, a good disciplinarian. He will be no help to you, Jack. He is simply taught and trained as the master of a national school, but he is thoroughly in earnest. I have told him that his most efficient assistant here will be yourself."
