Fig. 17 represents a third one, eight incheswide, and also divided into three bands, the outer ones being texture is uniform. The schists are succeeded by black, jointedslates, much contorted, and having the stratification often contain hard, bowlder-like masses of dark rock (272), some ofwhich are over a foot through, and evidently of foreign material. Inplaces they are almost numerous enough to form a west the slates show more of their usual bedded structure,though there is no regularity. On the east side of the vein there is about one hundred feet of hard,chloritic schist, strike north 15 degrees west. Beyond this the countryrock is a chloritic felsite schist (273).
