“1. _Batu bintang_, or star-stone. A small, transparent stone rounded by the action of water till it was almost spherical, with a rather rough surface. The _manang_ looked upon it as his badge of authority, and told the following story of the way he became possessed of it. Many years ago, in the interval between harvest and the next seed-time, he was working as a cooly in Upper Sarawak. There he had a dream in which he was visited by the being whom he looked upon as his guardian spirit. As in all cases when this spirit has had any communication to make to him, it appeared in the form of a tortoise. It told him that he must forthwith put himself under instruction in order to be qualified for the office of a _manang_; and that if he neglected this command all the spirits would be angry, and death or madness would be the penalty. When he awoke he found the _batu bintang_ by his side, and had no doubt it was the gift of the spirit. Accordingly, he did as he was bidden without loss of time. He acquired the professional knowledge and the stock-in-trade which were necessary, and was at last duly initiated with all the proper rites and ceremonies. “2. _Batu krat ikan sembilan_, or the petrified section of the Sembilan fish. This was a curious object which I could not quite make out. It was oblong in shape, about two inches long, one inch broad, and half an inch thick in the middle, but getting suddenly thinner towards the two edges till it became not more than one-sixteenth of an inch. The thick part was hollow, having a large, oval-shaped perforation going through it. It resembled a section from the middle of a large winged seed, but heavy for its size, and feeling like a stone. I could not of course test this by cutting or scraping. When used it is soaked for a time in water; the water is then given to the sick man to drink, or is rubbed gently upon the part of his body which is affected. “3. _Batu lintar_, or thunderbolt. A small, dark-coloured stone, about an inch and a half long and a quarter of an inch thick at the base, tapering to a sixteenth of an inch at the point, curved, and rather like a very small rhinoceros horn, and highly polished. It was probably the same kind of stone as that of which the stone implements found in the Malay Peninsula are made, which is also called _batu lintar_. It is pressed firmly against the body wherever pain is felt. “4. _Batu nitar_, another name for thunderbolt. A minute, four-sided crystal, half an inch long and about two lines thick. A charm to be used only in extreme cases. It is dipped in water and then shaken over the patient. If he starts when the drops of water fall upon his body he will recover, otherwise he will die.
