Analytical data

Result THREE ZONES CONTAIN THE PRINCIPAL ASBESTOS OF THE FIBER-BEARING HORIZON. THE FIBER OF THE LOWER VARIES IN LENGTH FROM 4 INCHES TO LESS THAN 3/4 INCH. AND, AS A RULE, IS OF VERY EXCELLENT QUALITY. THE MIDDLE ZONE IS USUALLY LESS THAN 6 INCHES THICK, BUT A LARGE PROPORTIONS OF ITS FIBER IS OF CRUDE NO. I AND NO. II LENGTH AND QUALITY. THE FIBER OF THE UPPER ZONE IS SLIGHTLY HARSH AT THE SURFACE, AND , DUE TO THE PRESENCE OF NUMEROUS, MINUTE SERPENTINE LENSES THROUGHOUT ITS VEINS, ONLY A MINOR PERCENTAGE OF THE MATERIAL EXPOSED IS OF CRUDE NO. I OR NO. II LENGTH.
