In China there is a strong belief that spots in rivers, creeks, and ponds where people have been drowned are haunted by devils that, concealing themselves either in the water itself or on the banks, spring out upon the unwary and drown them. To warn people against these dangerous elementals, a stone or pillar called "The Fat-pee," on which the name of the future Buddha or Pam-mo-o-mee-to-foo is inscribed, is set up near the place where they are supposed to lurk, and when the hauntings become very frequent the evil spirit is exorcised. The ceremony of exorcism consists in the decapitation of a white horse by a specially selected executioner, on the site of the hauntings. The head of the slaughtered animal is placed in an earthenware jar, and buried in the exact spot where it was killed, which place is then carefully marked by the erection of a stone tablet with the words "O-me-o-to-fat" transcribed on it. The performance concludes with the cutting up and selling of the horse's body for food. Amongst the numerous other creeks that have witnessed this practice in recent years are those adjoining the villages of Tsze-tow (near Whampoa) and Gna-zew (near Canton). Various of the lakes, particularly the crater lakes of America, were once thought to be haunted by spirits or devils of a fiery red who raised storms and upset canoes. _Sirens_ But by far the most fascinating of all the phantasms of the water are the sirens that haunted (and still occasionally haunt) rivers and waterfalls, particularly those of Germany and Austria. Not so very long ago on my travels I came across an aged Hungarian who declared that he had once seen a siren. I append the story he told me, as nearly as possible in his own words.
