46 12' K, at least upwards of 15,000 feet high, 

 according to Dana ( 551 ) ; still burning, always send- 

 ing forth smoke from the summit-crater : a volcano 

 covered with perpetual snow, of very fine and 

 regular conical form: on the 23d of November, 

 1842, a great eruption took place, which, according 

 to Fremont, has covered the country all around for 

 a great distance with ashes and pumice. 



Mount Adams, in 46 18' K, almost due east of Mount 

 St. Helen's; more than 112 geographical miles 

 from the coast : the last-named still-burning moun- 

 tain being only 76 miles therefrom. 



Mount Reignier *, also written Mount Eainier, in 

 46 48' N. ; E.S.E. from Fort Nisqually on Puget's 

 Sound, which is connected with the Fuca Strait; 

 a burning volcano : according to Edwin Johnson's 

 map in 1854, 12,330 feet high: it had violent 

 eruptions in 1841 and 1843 



Mount Olympus, in 47 50' K, only twenty-four 

 geographical miles south of the strait of San Juan 

 de Fuca, so long celebrated in the History of Dis- 

 covery in the Pacific. 



Mount Baker*; a great and still active volcano in 

 the territory of Washington (in 48 48'), rising to 

 a great height (? not yet measured), and of very 

 regular conical form. 



Mount Brown (16,000 feet?), and a little to the east 

 of it Mount Hooker (16,730 feet?), are, according 

 to Johnson, lofty mountains of ancient volcanic 

 trachyte in New Caledonia, in 52 N. and 118 

 and 120 W., remarkable therefore for being more 

 than 300 geographical miles from the coast.
