210 J. D. Dana— Geological Relations of the 
jifty feet ; and the more eastern portion is shown in figure 14. 
The strike is the same as that of the schi 
gneiss, with black mica, many visible grains and octahedrons 
ward and also to the westward ; the rock is quartzose, garnet- 
iferous, and includes chloritic magnetite with fibrolite, and 
other materials of the schist. 
ight to nine yards farther north, in the soda-granite, another 
band (d) exists, with the same strike—that of the schist— 
which outcrops for two hundred feet, or as far as the rocks in 
the direction are uncovered. This band is gray, like the last, 
and sparkles with the same pearly mica, but it is made up 
largely of brown staurolite in a half-granular form, showing 
but rarely SS remem faces, and contains also disseminated 
som 
another band (e), which contains much chloritic magnetite ; 
and a hundred beyond, another thin, gray, micaceous band re- 
ward in the granite (100 feet) is an assumption in this section; 
but considering that probably 5,000 feet, and more likely
