XC17 NOTES. 



forces are very active in Bosotlan : it had a great outpouring of lava on the 20th 

 of July 1844. 



Volcano of San Vicente*, west of Rio de Lempa, between the towns of Sacate- 

 coluca and Sacatelepe. A great eruption of ashes took place, according to 

 Juarros, in 1643; and in January 1835, a very destructive earthquake accom- 

 panied an eruption of long duration. 



Volcano of San Salvador (N. lat. 1 3 47'), near the town of the same name. 

 The latest eruption took place in 1656. The whole district around is exposed 

 to severe earthquake-shocks; that of the 16th of April 1854, which was not 

 preceded by any noise, overthrew almost all the buildings in San Salvador. 



Volcano of Izalco*, near the village of the same name ; often produces mu- 

 riate of ammonia. The first historically known eruption took place on the 23rd 

 of February 1770; subsequent eruptions, of which the light was seen at great 

 distances, took place in April 1798, 1805 to 1807, and 1825. (See above 

 p. 255 256, and Thompson, Official Visit to Guatemala, 1829, p. 512.) 



Volcan de Pacaya* (N. lat. 14 23'), about twelve miles south-east of the 

 town of New Guatemala, on the little Alpine lake Amatitlan ; a very active, 

 often flaming, volcano ; an extended ridge with three rounded summits. It had 

 great eruptions in 1565,*1651, 1671, 1677, and 1775; the last of these, in 

 which much lava flowed, was described by Juarros, who himself witnessed it. 



Next follow the two volcanoes of Old Guatemala, named De Agua and De 

 Fuego ; in 14 12' N. lat., near the coast. 



Volcan de Agua : a trachytic cone near Escuintla, higher than the Peak of 

 Teneriffe ; surrounded by masses of obsidian (evidences of ancient eruptions ?). 

 This volcano, which enters the region of perpetual snow, received its name from 

 a great inundation which was attributed to it, and which, in September 1541, 

 destroyed the first city of Guatemala, and occasioned the foundation of the second, 

 now called Antigua Guatemala, which was built more to the N.N.W. (Was the 

 inundation produced -by earthquake and melting of snow ?) 



Volcan de Fuego*, near Acatenango, twenty miles W.N.W. from the Volcan 

 de Agua. For their relative situation see the rare map (engraved at Guatemala 

 and given to me from thence) of the Alcalde mayor, Don Jose' Rossi y Rubi, 

 entitled, Bosqufjo del Espacio que media entre los estremos de la Provincia de 

 Suchitepeques y la Capital de Guatemala, 1800. The Volcan de Fuego is still 

 active, though much less so than formerly. The earlier great eruptions took 

 place in 1581, 1586, 1623, 1705, 1710, 1717, 1732, 1737, and 1799 ; but it 

 was not so much these as the destructive earthquakes which accompanied them, 

 that induced the Spanish Government, in the second half of the last century, to 

 forsake the second site, where the ruins of La Antigua Guatemala now stand,
