“Eh? Oh, no; but no fear of that. I can lick our keeper; pretty sure with a gun. Want to see my tongue and feel my pulse?” “Well, no,” said the Doctor, with a slight shrug of his shoulders. “I can pretty well tell.” “How?” “By your looks.” “Eh? Don’t look bad, do I?” “Rather.” “Something nasty coming on?” said the young man nervously. “Yes; bad bilious attack, if you are not careful. You have been drinking too much beer and smoking too many strong cigars.” “Not a bad guess,” said the young man with a grin. “Last boxes are enough to take the top of your head off. Try one.” “Thank you,” was the reply, and a black-looking cigar was taken from the proffered case. “Mind, I’ve told you they are roofers.” “I can smoke a strong cigar,” said the Doctor, quietly. “You can? Well, I can’t. Now then, mix up something; I want to be off.” “There is no need to give you any medicine. Leave off beer and tobacco for a few days, and you will be all right.” “But aren’t you going to give me any physic?” “Not a drop.” “Glad of it. But I say, the yokels down here won’t care for it if you don’t give them something.” “I have found out that already. There, sir, I have given you the best advice I can.” “Thankye. When am I to come again?” “Not until you are really ill. Not then,” said the Doctor, smiling slightly as he rose, “for I suppose I should be sent for to you.”
