According to the Annual Register, 1832-447, the fields of Kourianof, Russia, saw a fall of a combustible, resinous, yellowish substance which, when torn, had the tenacity of cotton. It covered an area of 600 or 700 square feet to a depth of at least two inches. In water, it had the consistency of resin, and was described as being the color of amber, elastic and smelled like “prepared oil mixed with wax.”
