breadth. On weatlic'rc(l surfaces tlie l)aii(ls show ]ilainly, Init on fresh sur- 

 faces they are often scarcely perceptible. Where ini(listurl>ed by granite 

 intrusions the bands strike about northeast and dip northwest at a very high 

 ande. Near the contacts with the granite they are much contorted. The 

 horublendic schists are sometimes banded, Ijut the l)anding is not so regular 

 as in the case of the micaceous rocks. 



There can be no (piestion that the granite is intrusive in the schists. 

 Its dikes and veins cut the schists in all conceivable directions. Perhaps 

 more frecjueutly than otherwise the dikes run parallel to the banding ol the

intruded rocks, but they nevertheless often cut across them, crumpling and 

 contorting the bands. The most easily accessible locality at which tliese 

 relations may be seen is on a little knob just south of the middle shaft of 

 the Champion mine, where the coarse ^vhite granite, so abundant farther 

 south, sends broad dikes with branching arms into a black, glistening 

 mica-schist (fig. 7). The same granite a little to the southwest contains 

 numerous large, sharp fragments of a similar scliist, which it has e^ddently 

 taken up in its passage to its present position.
