"Yes, we chased volcanoes. I became used to camping between sample hells of all known varieties. I got so that the fumes of a sulphur match seemed like a draught of pure, fresh air. Wherever any of the earth's pimples showed signs of coming to a head, there were we, taking part in the trouble. By and by the doctor got so thoroughly poisoned that he had to lay off. Back to Philadelphia we came. There an aged seafaring person, temporarily stranded, mulcted the Professor of a dollar--an undertaking that required no art--and in the course of his recital touched upon yonder little cesspool of infernal iniquities. An uncharted volcanic island: one that he could have all for his own; you may guess whether Dr. Schermerhorn was interested. "'That iss for which we haf so-long-in-vain sought, Percy,' he said to me in his quaint, link-chain style of speech. 'A leedle prifate volcano- laboratory to ourselves to have. Totally unknown: undescribed, not-on-the- chart-to-be-found. To-morrow we start. I make a list of the things-to- get.' "He began his list, as I remember, with three dozen undershirts, a gallon of pennyroyal for insect bites, a box of assorted fish hooks, thirty pounds of tea, and a case of carpet tacks. When I hadn't anything else to worry over, I used to lie awake at night and speculate on the purpose of those carpet tacks. He had something in mind: if there was anything on which he prided himself, it was his practical bent. But the list never got any further: it ceased short of one page in the ledger, as you may have noticed. I outfitted by telegraph on the way across the continent. "The doctor didn't ask me whether I'd go. He took it for granted. That's probably why I didn't back out. Nor did I tell him that the three life insurance companies which had foolishly and trustingly accepted me as a risk merely on the strength of a good constitution were making frantic efforts to compromise on the policies. They felt hurt, those companies: my healthy condition had ceased to appeal to them. What's a good constitution between earthquakes? No, there was no use telling the doctor. It would only have worried him. Besides, I didn't believe that the island was there. I thought it was a myth of that stranded ancient mariner's imagination. When it rose to sight at the proper spot, none were more astounded than the bad risk who now addresses you.
