There is an interesting mention of this incense in the Chinese book, _Shang-hai-king_. It was called _Fwan-hwan-hiang_ (by Japanese pronunciation, _Hangon-kō_), or “Spirit-Recalling-Incense;” and it was made in Tso-Chau, or the District of the Ancestors, situated by the Eastern Sea. To summon the ghost of any dead person—or even that of a living person, according to some authorities,—it was only necessary to kindle some of the incense, and to pronounce certain words, while keeping the mind fixed upon the memory of that person. Then, in the smoke of the incense, the remembered face and form would appear. [Illustration: The Magical Incense] In many old Japanese and Chinese books mention is made of a famous story about this incense,—a story of the Chinese Emperor Wu, of the Han dynasty. When the Emperor had lost his beautiful favorite, the Lady Li, he sorrowed so much that fears were entertained for his reason. But all efforts made to divert his mind from the thought of her proved unavailing. One day he ordered some Spirit-Recalling-Incense to be procured, that he might summon her from the dead. His counsellors prayed him to forego his purpose, declaring that the vision could only intensify his grief. But he gave no heed to their advice, and himself performed the rite,—kindling the incense, and keeping his mind fixed upon the memory of the Lady Li. Presently, within the thick blue smoke arising from the incense, the outline, of a feminine form became visible. It defined, took tints of life, slowly became luminous, and the Emperor recognized the form of his beloved At first the apparition was faint; but it soon became distinct as a living person, and seemed with each moment to grow more beautiful. The Emperor whispered to the vision, but received no answer. He called aloud, and the presence made no sign. Then unable to control himself, he approached the censer. But the instant that he touched the smoke, the phantom trembled and vanished. Japanese artists are still occasionally inspired by the legends of the Hangon-ho. Only last year, in Tōkyō, at an exhibition of new kakemono, I saw a picture of a young wife kneeling before an alcove wherein the smoke of the magical incense was shaping the shadow of the absent husband.[6] [6] Among the curious Tōkyō inventions of 1898 was a new variety of cigarettes called _Hangon-sō_, or “Herb of Hangon,”—a name suggesting that their smoke operated like the spirit-summoning incense. As a matter of fact, the chemical action of the tobacco-smoke would define, upon a paper fitted into the mouth-piece of each cigarette, the photographic image of a dancing-girl.
