of Elizabctli. The coals and tiuxes brought from Enghmd, the anvils and 

 trenches, the blooms made in testing for gold, the i)rospecting-holes, and the masses 

 of the ''black stone like unto coal," which the London jewelers had declared 

 to be gold-bearing, and the full traditions of the natives, all seem like a cliaptei- 

 out of our own Western history. "His long and intimate association with the 

 Innuit makes his book a mine ot information in Ethnology, and the geological 

 collections made by him give us the only information concerning the occurrence 

 of the Lower Silurian in the whole of Ai-ctic America north of Kui)ert's Land, 

 with the single exception of the fossils collected by Captain McClintock and 

 described by Houghton.*" These were : 



1. Maclurea arctica, Houghton, near M. magna, in white Silurian dolomite from 



Depot Bay, in Bellof s Straits, 72° N., 94° W. 



2. The same with Chcetefes lycoperdon, H., associated with Upper Silurian fossils 



at Fury Point, 72o 50' X., 92° W. 

 r5. ^[. arctica, Hough., Ormoceras crebriseptum, H., Huronia vertebralis, Stokes, 



Orthoceras Canademe, B., Receptacidetes neptuni, Def., from the west coast 



of King William's Land. 

 4. Orthoceras moniliforme, H., Cape Riley, Xorth Devon. 



These localities lie many hundred miles to the northwest of Frobisher Bay, 

 and are characterized over wide areas by buft' and cream-colored dolomites and 

 limestones, are succeeded by the limestones of the Upper Silurian and Carbon- 

 ic. A reddish-gray quartzite in contorted layers, the ends of the laminse coated with a 

 curious coraloidal deposit of brick-red limonite. Locality, Etah Bay. 



14. Beautiful milky quartz, limpid, with pale purple opalescence. Locality, Etah Bay. 



15. Coarse garnetiferous gneiss. From Sontag's grave, at Port Foulke, North Greenland. 



16. Many fragments of same opalescent quartz as above (5). From Sontag's grave. 



17. Coarse granite ; gray translucent quartz ; flesh-colored feldspar in large crystalline 

 masses, and no mica. Locality, Esquimaux Point, North Greenland. 



18. Flesh-colored garnetiferous gneiss, black mica. Esquimaux Point. 



19. A very even-bedded friable quartz sandstone, splitting in laminae 17™™ thick, and quite 

 free from any impurity. The specimen is pure enough for the manufacture of glass, resembling 

 <losely the St. Peter's sandstone at St. Paul. 



It is labeled, "From Cape Alexander, L. 78° 20' N., L. 7.3° W." 



These sandstones are mentioned by Sutherland as stretching from Wolstonholme Sound to 

 (Jape Alexander, nearly always horizontal (Proc. Geo. Soc. ISo^, p. 298), and are compared by 

 McClintock with Ihe sandstone from Byam Martin's Island from the l)ase of the Carboniferous. 

 (Journal Roy. Dublin Soc. 1857, p. 199.) 



20. Coarse granitoid gneiss with large red garnets (12-14'"™). Locality, Cape Isabella, 

 Grinnell Land. 



21. Laminated garnetiferous gneiss banded with Idack mica. Cape Isabella, 



22. Gray granular quartzite, the grains separated by films of kaolin. Cape Isabella.
