quartz is present, but very little biotite is found and apparently 

 no feldspar. Instead of the last named mineral, however, a great 

 number of brown garnets occur to such an extent as to give the 

 rock a brownish appearance. The largest ones are more than one 

 eighth of an inch in diameter. Among the whitish quartz and 

 between its layers they produce a very striking appearance, ly- 

 ing mostly separated from each other. On the surface, where 

 the rock is disintegrated, the garnets number about fifteen to 

 eighteen to the square inch, lying in grooves of greater or less 

 depth, thereby giving the surface of the rock a dotted appearance.
