But this language had not remained stationery since the period of 1830. It had continued to evolve and, patterning itself on the progress of the century, had advanced parallel with the other arts. It, too, had yielded to the desires of amateurs and artists, receiving its inspiration from the Chinese and Japanese, conceiving fragrant albums, imitating the _Takeoka_ bouquets of flowers, obtaining the odor of _Rondeletia_ from the blend of lavender and clove; the peculiar aroma of Chinese ink from the marriage of patchouli and camphor; the emanation of Japanese _Hovenia_ by compounds of citron, clove and neroli. Des Esseintes studied and analyzed the essences of these fluids, experimenting to corroborate their texts. He took pleasure in playing the role of a psychologist for his personal satisfaction, in taking apart and re-assembling the machinery of a work, in separating the pieces forming the structure of a compound exhalation, and his sense of smell had thereby attained a sureness that was all but perfect. Just as a wine merchant has only to smell a drop of wine to recognize the grape, as a hop dealer determines the exact value of hops by sniffing a bag, as a Chinese trader can immediately tell the origin of the teas he smells, knowing in what farms of what mountains, in what Buddhistic convents it was cultivated, the very time when its leaves were gathered, the state and the degree of torrefaction, the effect upon it of its proximity to the plum-tree and other flowers, to all those perfumes which change its essence, adding to it an unexpected touch and introducing into its dryish flavor a hint of distant fresh flowers; just so could Des Esseintes, by inhaling a dash of perfume, instantly explain its mixture and the psychology of its blend, and could almost give the name of the artist who had composed and given it the personal mark of his individual style. Naturally he had a collection of all the products used by perfumers. He even had the real Mecca balm, that rare balm cultivated only in certain parts of Arabia Petraea and under the monopoly of the ruler. Now, seated in his dressing room in front of his table, he thought of creating a new bouquet; and he was overcome by that moment of wavering confidence familiar to writers when, after months of inaction, they prepare for a new work. Like Balzac who was wont to scribble on many sheets of paper so as to put himself in a mood for work, Des Esseintes felt the necessity of steadying his hand by several initial and unimportant experiments. Desiring to create heliotrope, he took down bottles of vanilla and almond, then changed his idea and decided to experiment with sweet peas. He groped for a long time, unable to effect the proper combinations, for orange is dominant in the fragrance of this flower. He attempted several combinations and ended in achieving the exact blend by joining tuberose and rose to orange, the whole united by a drop of vanilla.
