13. In the "London Quarterly Journal of the Geological Society for 

 August, 1851," there is a notice of the work of Dr. C. Grewink on the 

 Orography and Geognosy of the North-west Coast of North America, and the 

 outlying Islands. This article gives an account of Mastodon relics recently 

 discovered at Unal, &c, on this coast, and is of great interest, as it serves 

 to confirm the statement, long since made, that the relics have been found 

 as far north as the sixty-fifth degree of latitude ; a statement, the exactness 

 of which has been doubted. 



"Diluvial formations were recognized,, by means of their Mastodon 

 remains, at LTnalaschka, the Pribulow Islands, Norton Bay, Kotzebue Sound, 

 and the coast further north of this ; and indications of these deposits were 

 observed at Cook's Inlet, and on the Aliaska Coast. The distribution, 

 however, both of alluvium and diluvium, can only be correctly defined when 

 the country is better known." 



The banks of the Shawangunk and Yfaalkil rivers in Orange County, 

 New York, situated to the west of the Hudson river, as we have elsewhere 

 said, are the fertile beds of Mastodon skeletons. Three out of five of the
