The plants were found near the mouth of Fraser’s River, and 
indicate probably the commencement of the deposits of the 
coal strata, which are largely developed in the neighboring 
island of Vancouver, and along the coasts and islands of Russian 
America. ee 
The interior of Russian America, like that of Oregon, is unex- 
plored ; but, in the work of Grewingk (Beitrag zur Kenntniss 
der orographischen und geognostischen Beschaffenheit der Nord- 
West Kuste Amerika’s), and in the Geological Appendix to Capt. 
Beechey’s Voyage to Behrings Straits, by Dr. Buckland, we have | 
a tolerably complete account of the chief formations occurring 
along the coast, and on the neighboring islands, from 52° N. lat. 
to ring’s Straits.
