IT WASN’T LONG before he had become a specialist in the field of distillation. He discovered-and his nose was of more use in the discovery than Baldini’s rules and regulations-that the heat of the fire played a significant role in the quality of the distillate. Every plant, every flower, every sort of wood, and every oil-yielding seed demanded a special procedure. Sometimes you had to build up the hottest head of steam, sometimes you just left it at a moderate boil, and some flowers yielded their best only if you let them steep over the lowest possible flame.

It was much the same with their preparation. Mint and lavender could be distilled by the bunch. Other things needed to be carefully culled, plucked, chopped, grated, crushed, or even made into pulp before they were placed in the copper kettle. Many things simply could not be distilled at all-which irritated Grenouille no end.

Having observed what a sure hand Grenouille had with the apparatus, Baldini had given him free rein with the alembic, and Grenouille had taken full advantage of that freedom. While still mixing perfumes and producing other scented and herbal products during the day, he occupied himself at night exclusively with the art of distillation. His plan was to create entirely new basic odors, and with them to produce at least some of the scents that he bore within him. At first he had some small successes. He succeeded in producing oils from nettles and from cress seeds, toilet water from the fresh bark of elderberry and from yew sprigs. These distillates were only barely similar to the odor of their ingredients, but they were at least interesting enough to be processed further. But there were also substances with which the procedure was a complete failure. Grenouille tried for instance to distill the odor of glass, the clayey,............
