Zuni, where the Paso de Zuni is still 7944 feet high ; Zuni Viejo, the old mined 

 Pueblo drawn by Mollhausen in Whipple's Expedition ; and the present inhabited 

 Pueblo de Zuni. Forty geographical miles north of the last-named place, there 

 is still a very small isolated volcanic district near Fort Defiance. Between the 

 village of Zuili and the slope to the little Colorado River (Colorado Chiquito), 

 there lies uncovered the " petrified forest," of which an excellent description 

 and drawings have been given by Mollhausen in 1853 in a memoir sent to the 

 Geographical Society of Berlin. Among the silicified coniferae, fossil tree-ferns 

 are also interspersed, according to Marcou (Re'sume' explic. d'une Carte geoL 

 p. 59).

 cited itinerary map of 1855. 



( 546 ) p. 398. The French names introduced by Canadian fur-hunters are 

 in general use in the country and in English maps. The relative positions of 

 the extinct volcanoes are, according to the latest determinations, as follows : 

 Fremont's Peak, 43 5' N., 110 8' W.; Trois Tetons, 43 38' N., 110 48' W.; 

 Three Buttes, 43 20' N., 112 40' W.; Fort Hall, 43 0' N., 112 23' W.

 Tinkham's account of the Three Buttes, in the same, p. 167 and 226 230;

 Monte Diablo Range which has broken through volcanic rock, see also John 

 Trask, On the Geology of the Coast Mountains and the Sierra Nevada, 1854,

( Mq ) p. 400. Dana (p. 615 and 640) estimated the volcano St. Helen's at 

 16.000 feet, and Mount Hood, therefore, at less than that height; according to 

 others, Mount Hood would have the great elevation of 18,316 feet, 2526 feet 

 higher than Mont Blanc, and 4746 feet higher than Fremont's Peak in the 

 Bocky Mountains. Thus, according to the latter statement (Landgrebe, Natur- 

 geschichte der Vulkane, Bd. i. S. 497), Mount Hood would, on the one hand, be 

 only 571 feet lower than Cotopaxi; while, according to that of Dana, on the 

 other hand, it would only be 2550 feet above the highest summit in the Rocky 

 Mountains. I always think it desirable to call attention to such " variantes 

 lectiones."

 feet according to Wilkes, and 13,535 feet according to Simpson.
