The young man gave me his report; but what counted was the way he had gone after his material, his curiosity, his conviction that it was important since I wanted it. I thought I had my man. A few more trials convinced me John M. Siddall was a find. He at that time was an associate of Frank Bray in the editing of _The Chautauquan_, the headquarters of which had been shifted to Cleveland from Meadville. When Siddall once understood what I was up to he jumped at the chance—went to work with a will and stayed working with a will until the task was ended. He was a continuous joy as well as a support in my undertaking. Nothing better in the way of letter writing came to the _McClure’s_ office. In time everybody was reading Siddall’s letters to me, whether it was a mere matter of statistics or a matter of the daily life in Cleveland of John D. Rockefeller, the head of the Standard Oil Company. If anything in or around Ohio interested the magazine the office immediately suggested, “Ask Sid.” And Sid always found the answer. Mr. McClure and Mr. Phillips began to say, “We want Sid as soon as you are through with him.” Sid saw the opportunity, and as soon as I could spare him in Ohio he joined the _McClure’s_ staff. I had been at work a year gathering and sifting materials before the series was announced. Very soon after that, Mr. McClure dashed into the office one day to tell me he had just been talking with Mark Twain, who said his friend Henry Rogers, at that time the most conspicuous man in the Standard Oil group, had asked him to find out what kind of history of the concern _McClure’s_ proposed to publish. “You will have to ask Miss Tarbell,” Mr. McClure told him. “Would Miss Tarbell see Mr. Rogers?” Mark Twain asked. Mr. McClure was sure I would not ask anything better, which was quite true. And so an interview was arranged for one day early in January of 1902 at Mr. Rogers’ home, then at 26 East Fifty-seventh Street. I was a bit scared at the idea. I had met many kinds of people, but this was my first high-ranking captain of industry. Was I putting my head into a lion’s mouth? I did not think so. It had become more and more evident to me that any attempt to bite our heads off would be the stupidest thing the Standard Oil Company could do, its reputation being what it was. It was not that stupid, I told myself. However, it was one thing to tackle the Standard Oil Company in documents, as I had been doing, quite another thing to meet it face to face. And then would Mr. Rogers “come across”? Could I talk with him? So far my attempts to talk with members of the organization had been failures. I had been met with that formulated chatter used by those who have accepted a creed, a situation, a system, to baffle the investigator trying to find out what it all means.
