Keep a Log Before You Keep a Journal

The man who trained me kept two notebooks in the same bag for forty years and never once let their contents mix, and I did not understand why until I had ruined enough of my own writing to need his answer.

I want to describe his method in full, because it is not mine, I did not invent it, and I think crediting it accurately matters more than folding it quietly into my own practice as though I had arrived at it alone. His name was Torbjørn, and by the time I worked under him he had been counting waders on the same stretch of coast for longer than I had been alive.

The two notebooks

The first notebook was the log. Every entry had a time, a location, a count, a weather reading, and nothing else. No adjectives, no interpretation, no sentence longer than the facts required. If a rare bird turned up, the log recorded the sighting the same way it recorded a routine one: time, species, number, conditions. The log did not care whether a day felt significant. It recorded what was true regardless of how the day felt.

The second notebook was the journal, and he did not open it in the field at all. It came out in the evening, at a desk, and it was where he was allowed to be wrong, uncertain, moved, speculative, all the things the log deliberately excluded. He once told me the journal was where he was allowed to guess, and the log was where guessing was forbidden, and the entire method depended on never letting a guess from the journal quietly migrate back into the log disguised as a fact.

What happens when the two get mixed

I did not follow his split for the first four years I kept field notes, and I can show you exactly what it cost me. In a single notebook, I once wrote: "0640, low tide, three godwits, seems like fewer than last spring, probably the cold snap in March." By the time I came to write the book that used those notes, eleven years later, I could no longer tell which part of that sentence was the count and which part was my evening speculation about why the count was what it was. "Fewer than last spring" was an impression, not a comparison against the actual number from the previous year, which I had also, that same spring, failed to log precisely because I had been writing impressions instead of counts on the days that felt uneventful.

Torbjørn's log would never have produced that sentence, because his log entry would have been three numbers, this spring's count, an unambiguous location, a weather code, and his journal entry that evening could have speculated about the cold snap all it wanted without threatening the log's integrity, because the two lived in different books and nobody, including him eleven years later, would ever confuse a guess for a fact.

The disagreement he and I actually had

I should say plainly that Torbjørn and I did not agree on one part of this, and I lost the argument for years before coming around. My honest objection was that the split was overcautious, that a good enough memory could keep guess and fact separate without two physical books, and that carrying two notebooks in bad weather was one more thing to lose or ruin. He argued, and I now think correctly, that memory is exactly the thing that cannot be trusted to keep guess and fact apart, because memory is itself already a journal, already interpretive, and asking it to also hold the log meant the log had already been contaminated before a single word reached paper. The physical separation was not fussiness. It was the only mechanism that reliably worked, because it did not depend on the one faculty, memory in the moment of writing, that the whole problem was caused by in the first place.

What I kept from him

I now keep two files, not two notebooks, but the split is exactly his. The log has dates, counts, weather, page numbers if I am tracking a manuscript's chapter word counts, nothing else. The journal has everything the log refuses: guesses, moods, half formed theories about why a chapter is not working. When I eventually write the book, I go to the log for what actually happened and the journal for what I thought it meant, and I no longer confuse the two, because they have never, since I adopted his method, been allowed to sit on the same page.
