"Why, his duties in the store have not been so onerous of late," said Mr. Ludolph, in some surprise. "It is not der vork in der store, but he vork nearly all night too. Den he haf had trouble, I know he haf. Do he say no vort about him?" Dennis gave Mrs. Bruder a sudden warning look, and then, through the strong instinct to guard his secret, roused himself. "Is it anything serious, doctor?" he asked. The physician looked grave, and said, "Your pulse and whole appearance indicate great exhaustion and physical depression, and I also fear that fever may set in." "I think you are right," said Dennis. "I feel as if I were going to be ill. My mind has a tendency to wander. Mr. Ludolph, will you permit me to go home? If I am to be sick, I want to be with my mother." Mr. Ludolph looked inquiringly at the doctor, who said significantly, in a low tone, "I think it would be as well." "Certainly, Fleet," said his employer; "though I hope it is only a temporary indisposition, and that you will be back in a few days. You must try and get a good night's rest, and so be prepared for the journey in the morning." "With your permission I will go at once. A train leaves now in an hour, and by morning I can be at home." "I scarcely think it prudent," began the doctor. "Oh, certainly not to-night," said Mr. Ludolph, also. "Pardon me, I must go at once," interrupted Dennis, briefly and so decidedly that the gentlemen looked at each other and said no more. "Mr. Bruder," he continued, "I must be indebted to you for a real proof of your friendship. In that drawer you will find my money. The key is in my pocketbook. Will you get a carriage and take me to the depot at once? and can you be so kind as to go on home with me? I cannot trust myself alone. Mrs. Bruder, will you pack up what you think I need?" His faithful friends hastened to do his bidding. "Mr. Ludolph, you have been very kind to me. I am sorry this has occurred, but cannot help it. I thank you gratefully, and will now trespass on your valuable time no longer." Mr. Ludolph, feeling that he could be of no further use, said: "You will be back in a week, Fleet. Courage. Good-by." Dennis turned eagerly to the doctor and said: "Can you not give me something that will reduce the fever and keep me sane a little longer? I know that I am going to be delirious, but would reach the refuge of home first." A prescription was given and immediately procured, and the doctor went away shaking his head. "This is the way people commit suicide. They know no more about, or pay no more heed to, the laws of health than the laws of China. Here is the result: This young fellow has worked in a way that would break down a cast-iron machine, and now may never see Chicago again." But Dennis might have worked even in his intense way for months and years without serious harm, had not a fair white hand kept him on the rack of uncertainty and fear. Not work, but worry, makes havoc of health.
