564 Professor Emerson on HalVs GeolofficaJ Collections 



Labeled, '' Azoic Rocks, Frobisher Bay." 

 C7. Hornblende schist. 



Several j)ieces resembling GO, but finer grained and more scbistose. 

 Labeled, " From various places uj) Bay of Frobisher and near head of it." 



G8. QUAKTZITE. 



Three large masses of a compact jaspery quartzite of deep red color and 

 broad conchoidal fi'acture. They are only slightly banded by a slight concentra- 

 tion of the iron in broad bands, and are remarkably homogeneous, and free from 

 any other impurities except the red oxyde of iron. They were marked (1) in ink, 

 and seem to me to have been gathered by Hall during his first long excursion 

 along the north shore of Frobisher Bay, but of this I cannot be certain. 



69. QUAETZITE. 



Several pieces of a rusty-red quartz sandstone, which seem to be only 

 weathered pieces of the same kind as 68. 



70. Quartzite. 



A water-worn pebble of a similar deep red quartzite, slightly micaceous, 

 from French Head, Field Bay. 



The rocks described under the last three numbers might almost as well 

 have been associated with the Devonian sandstone of Lupton Sound, described 

 later (]Slo. 108), or the sandstone from Cape Alexander (vide ante No. 19). It is, 

 however, much more indurated, especially l!^o. 68, and has a much older look.
