"Gazers" use different methods. Some look into water contained in a vessel, some into a drop of blood, some into ink, some into a round opaque stone, some into mirrors, and many into some form of crystal or a glass ball. Indeed, the "gazer" seems to be quite independent as to the medium of his sight-seeing, so long as he has the "power." This "power" is put also to a great variety of uses. Australian savages depend on it to foretell the outcome of an attack on their enemies; Apaches resort to it to discover the whereabouts of things lost or stolen; and Malagasies, Zulus, and Siberians to see what will happen. Perhaps its most general use has been to discover lost objects, and in this practice the seers have very often been children, as we shall see was the case in the exhibition which gave Joe Smith his first idea on the subject. In the experiments cited by Lang, the seers usually saw distant persons or scenes, and he records his belief that "experiments have proved beyond doubt that a fair percentage of people, sane and healthy, can see vivid landscapes, and figures of persons in motion, in glass balls and other vehicles." It can easily be imagined how interested any member of the Smith family would have been in an exhibition like that of a "crystal-gazer," and we are able to trace very consecutively Joe's first introduction to the practice, and the use he made of the hint thus given. Emily C. Blackman, in the appendix to her "History of Susquehanna County, Pennsylvania" (1873), supplies the needed important information about Joe's visits to Pennsylvania in the years preceding the announcement of his Bible. She says that it is uncertain when he arrived at Harmony (now Oakland), "but it is certain he was here in 1825 and later." A very circumstantial account of Joe's first introduction to a "peep-stone" is given in a statement by J. B. Buck in this appendix. He says:--
