 familiar with the ah-i-ining sight* returned to their huts, 

 and went down to the mountains of Aguasarco ami Santa 

 Ines, to admire the sheaves of fire thrown out by an infi-

exaggeration in the report of some of the oid Indians, who 

 say, that the plains of Jorullo were uninhabitable for seve- 

 ral years, and even to a considerable distance from the 

 ground raised up, on account of the excessive heat. 

 Two rivers Near the cerro of Santa Ines t ! .e traveller is still shown 



lost, the rivers of Cuitimba and San Pedro, the limpid waters 



of which formerly refreshed the sugarcanes on the estate 

 of Don Andrew Pi mantel. These springs were lost in the

 xrmchltrattd" [ near 22.00 yards] to the westward, in the soil that has been 

 elevated, two rivulets are seen to break out of the clayey 

 dome of the furnaces, exhibiting themselves as thermal 

 waters, in which the thermometer rises to 52*7° [1 26*80 D F.]. 

 The Indians still give these the names of San Pedro and 

 Cuitimba, because in several parts of the Malpays large 

 bodies of water are supposed to be heard running from east 

 to west, from the mountains of Santa Ines to the estate of 

 the Presentation. Near this estate is a brook, that emits, 

 Sulphurous" sulphuretted hidrogen gas : it is more than 7 met. [near 8 

 yards] wide, and is the most copious hidrosulphurous spring 

 I ever saw.

 thermometer rose to 8">° [l8.5°|. From these cracks, and ire heaps 

 of scoria* that cover considerable hollows, the descent into the crater 

 is not without danger.
