During the fifteen years he had been working on his Spanish Adventurers in North America , this room had been his centre of operations. There had been delightful excursions and digressions; the two Sabbatical years when he was in Spain studying records, two summers in the Southwest on the trail of his adventurers, another in Old Mexico, dashes to France to see his foster-brothers. But the notes and the records and the ideas always came back to this room. It was here they were digested and sorted, and woven into their proper place in his history.
Fairly considered, the sewing-room was the most inconvenient study a man could possibly have, but it was the one place in the house where he could get isolation, insulation from the engaging drama of domestic life. No one was tramping over him, and only a vague sense, generally pleasant, of what went on below came up the narrow stairway. There were certainly no other advantages. The furnace heat did not reach the third floor. There was no way to warm the sewing-room, except by a rusty, round gas stove with no flue—a stove which consumed gas imperfectly and contaminated the air. To remedy this, the window must be left open—otherwise, with the ceiling so low, the air would speedily become unfit to breathe. If the stove were turned down, and the window left open a little way, a sudden gust of wind would blow the wretched thing out altogether, and a deeply absorbed man might be asphyxiated before he knew it. The Professor had found that the best method, in winter, was to turn the gas on full and keep the window wide on the hook, even if he had to put on a leather jacket over his working-coat. By that arrangement he had somehow managed to get air enough to work by.
He wondered now why he had never looked about for a better stove, a newer model; or why he had not at least painted this one, flaky with rust.
